Ttii. r Horace 'VT. Beet, of Chicago, is the origi nator of the Ox ord initiate, which has the approval of the American Association of Professors of Dancing. At a Kenwood man sion last week, says the Chicago Times, the new dance was tried od and accepted hy the ultra-fashionables. "Position as for minute, 1.2, 3, 4," said Prof. Beek, who was present on the occasion, and off the company glided, as accustomed dancers will. Ihen immediately the gallop balance and gallop in waltz position lollowed. The dance was accepted and the professor was so lupp that he wanted to go ou on the street and call every man "brother." "I have so Irequently been asked to in troduce the minuet and everyone seemed so axious to dance it," said Mr. Beek, "I was convinced that the minuet would be a popu lar ballroom dance if relieved of part of its slowness or pokyness. It required more tnan two to dance it, and hence could not be popular at large gatherings. I set my self to overcome both these difficulties, and the Oxford is the resuit. One couple or 100 couples may dance it, the beauty of the dance is increa-ed by the concerted motion i a larse company. All must be together for minuet with the music, and then off for the galop. It :s thus stately enough to be enjoieu by ladies and gentlemen who conld not and would not dauce anything in poor lasts. The minuet and also the galop have always been popular in good societv, and I am aware that no matter how strongly our society o: teachers recommend a dance society itselt must put its stamp of approval or disapproval upon it to make or luin it." Tnc Laughing Daxce The "Jline haha," or laughing dance, is Prof. Augustus Bournique'o latest. Its name is intended to indicate its peculiar motion. It is a ver sion of the glide-mazurka, and is danced to mazurka time in the first movement, in cither military schottuche or Berliu posi tion. The tempo is of a polka-redo wa order, to which, i wished, the plain polka may be danced. Prof. Bmirnique believes that the already existing 1,100 figures oi the german will be increased by several hundred Unique End pretty ones this siason. Insane Asyivum Danced Every large and well equipped insane asylum of this countrv has a dancing hall for its inmates. It furnishes recreation lor those who are not entirely uncontrollable, and is approved bv the most eminent of insanity specialists. Tne great State asylum at Columbus, 0., with its thousands ot un oriunates, has a large hall with a fine waxed floor, which on every Thursday evening presents an inter esting scene. At S o'clock the ballroom doors are thrown open. Down the halls, in cuarge oi attenaants. come the guests. The men come irom one part o the liniiding, and from an opposite direction march the women. "W'il!i all their queer notions and weak fcrjins the female portion o( an iusane asy- lUTuTetains one nev;r to be effaced idiosyn crasy. They love finery and dress. So'me of the costumes are fearfully and wonderfully arrauged. But alter all it is not a scene lor mirth, for of all sad places in the world that within the walls of &uch an institution is the saddest. But a burden oi sorrow brought the motley gath ering here! What tales oi woe in thecauses for all this mental wreck! The lunntics seem to realize that the balls are 'or their good. Slanv of them are in sane only on some particular subject, and to tiietn an evening with muMc, bright light, flowers and company is an eujoyment. Others look forward to the affair as a chance for a good romp, and some seem to believe that tnev are going to dance simply because it is a partol their punishment and take it liken child does castor oil. Hound dances lo not succeed. Lunatics don't like them. Quadrille alter quadrille rounds out the ceaiug of recreation. The Belle ok London The full dress is not the proper thing lor the belle of the ball in London this season, says a lady cor respondent of the St. Louis Post-Dispatch. Pretty., dimpled, rounded arms are to be covered. At country-house dances and in nil our preparations tor later winter festivi ties, we are going in for pure womanliness in the thapeoi white crepe or embroidered Bull from wrists to shoulders. The new lancing dresses are really pretty, with flower carlands looping their flounces and sprinkled with jewels. The pessimists say that the large sleeves will be bothersome in the dance. This may lie, but they are certainly quaint and charm ing, especially as a reliel from the familiar perspect ve ot scrawny arms. By the way, it seems to be generally conceded that women are a great deal better looking now than they used lo be, but after all one is forced to allow that it doesn't yet need any large al lowance of beauty to win for a girl with good backing tne reputation of a reigning belle. Fad or the Season. Kach season brings with it its own particular "fad." Tne "lad" of the social season of 1890-91, says the Iew York Telegram, is an ankle lcind of fold fetuddtd with gems for the beauty oi the ball room. These ankle orna ineuts are decided novelties. Within the past week or two several have been made by leading jewelers. The anklet o Cleopatra's realms gathering reputation in East India and Persia Irom Circassian, Turkish and Egyptian women h.s at last established itsel among our own sisters, who, of all women, possess the .acuity o. quick appre ciation of the beauti-ul. The ornaments of modern construction difler widely from the well-known bracelet, m the act that they do not unclasp by simply touching a spring, being provided with an ingenious slidiug tube at each side oi tne circle, allowing the anklet to expand J Mimcienuy to pass over tne loot and then to clasp at any sze necessary to please the wearer. This contrivance is adapted so that should the piece of jewelry come undone accidentally it d-es not lalfto the floor, to be kicked away in the dizzy whirl of the ball room, but remains in position on the foot. A rare piece of ankle jewelry, by Tiffany, is worn by His? Vesta Hastings, who is well known lor her exquisite taste in her great variety o costumes, rarely appearing in the same oue twice throughout an eutire month. This one is surely the handsomest one ever proaucea. .iiuougn apparently large it is very light in weight, the wearer hardly noticing the round band of cold, studded with immense Persian turquoise. To the front and posed between six rampant lion heads is another and very important tur quoise, secured in a beautiful setting of laminated gold ornament. The whole sur face of the metal is a mass ol carved dec oration. It must be admitted that well shaped ankles are necessary to support such extrav agant playthings, but New York is noted for its women of good taste, and they can well adorn themselves u far as their pock ets will permit It is needless to say that fine shoes and the best stockings must be taken into consideration by the wearers. There is no limit to the proportion for ankle ornaments. From the tiny wire ringlet, with but a singlo gem, to the beautifully pierced and enameled circle of gold. The Skirt Dance. I hope I shall not be considered egotistical, writes Amelia Glover, the popular danseuse, in the New York Horning Journal, if I say that skirt dancing is now the popular fad. We have outgrown that period in which the ballet used to engross the whole attention of the play-going public Nowadays, if I gauge the taste o! the pitrons of the play cor rectly, a modest dance is preferred to that which leaves nothing to the imagination. Grace modest grace, I mean is now pre ferred to short skirts, tinsel and a wealth of lace. The success of the skirt dance is largely due to the sinuous, intoxicating, rhythmical movement employed. But it is also necessary that the dancer should be in per ect sympathy with her art. To attain success in skirt dancingthe dancer must not have the slightest suspicion of embonpoint. She must above things possess not only the quality o being able to dance artistically, lut must also use a smile, a bit of gesticula tion, an undefinable something such as .trench danseuscs use in their art No artist of to-day can expect success fully to compete with Taglioni and Fanny Elssler, who 40 years ago were the rage. I have seen pictures of the skirts worn by them, and 'find they are no longer than those used by the skirt dancers of to-day. Orthe two I pre er the long skirt dance to the short one, not because I consider the latter in the slightest degree immodest, but for the reason that it folds and un olds itself in unison with the dancer's body, and multi plies the grace of every movement. The Dress Coat Must Go The young men of the Equestrian and Kenwood Clubs, says the Chicago Times, are a-weary of be ing arrayed in sad-hued garb like unto waiters. The clawhammer coat and doeskin trousers Have become unspeakably common, and at their private balls this season they will appear in silken"tockings and knee breeches, fancy coats aad waistcoats of rich brocade, and low shoes, with massive steel, silver or jeweled buckles. They have wisely decided not to adopt the Parisian waistcoat of bright scarlet. They rrefer being gen teel and English to being French and loud. Their waistcoats will, therefore, be gor geous, but they will not scream and .inter rupt the flow of polite conversation with their diabolic noise. For the conversa-inn will be polite. There will be a studied effort to reproduce in the intercourse of the club members the same old-fashioned cour tesy and deportment that made the ancient days famous in history. In short. Beau Brummell is to be many times duplicated, and there is to be something "new under the sun," even though it is but a revival of the things that were. The Kenwood and Equestrian Clubs have many supporters in the East. At Tuxedo and at several private receptions of the "400" elsewhere the men sported knee breeches, splendid waistcoats and colored coats. In England the regulation court costume is much the same, the Windsor or royal nuiform being a blue coat worj over while satin waistcoat and knee-breeches, white silk stockings and diamond-buckled shoes. So far no special costume for ladies has been pronounced upon. Doubtless, the lair ones will not be outdone, but will honor the clubs on "ladies' evening" by appearing in the powdered hnir that heightens the charms of the complexion and the tiny "beauty patches" of the period. Oi course, they will look lovely. Otero Writes of Spain. All Span iards, it might be said, writes Otero, the popular dancer, in the New York Herald, are born dancing, and there would seem to be no need to apologize lor them on that ac count, for dancing has been popular in all ages ana among all nations. Evei the sav ages use their feet rather than their heads to express their ideas. Bushmen jump about to imitate calves. Hottentots go on all lours to imitate the baboon, and execute one movemeul in which they imitate the buzzing of a swarm of bees. "Other savage nations imitate by means of dancing hunts after wild animals, and in Tasmaui-- a dance by the women describes their hunt after the opossum, divmir alter shellfish. digging for roots, nursing children, while one very exciting movement describes a quarrel with a husband. Another dance is where by gestnie they taunt a chieftain with cowardice and urge bim to come lor ward to recount his courageous deeds. As 1 say, the Spanish people seem to be born with their dancing shoes on, and as a rule they aie good dancers, because, as the .French say, what we love to do we gener ally do well. The proverbs tell us that "A pair of light shoes is not all that is wanted lor dancing," and "if a bear will learn to dance he must go to school early." The taudango is the oldest national dance of Spain, especially in the district or Andalusia. Some say it was introduced by the Moors, while others claim it was there be ore they came to the country. This dance interprets what mar be called a pas sionate love sung. The opening, or invita tion, is a wild bit of music, accompanied by a Boisterous song, wjiich ends in a loud chorus ol abl all's! It is danced by couples male and female, in what is called three four time. The musical accompaniment is a guitar, a tambourine, sometimes castanets are used to keep time, or the spectators makeup for the omission of the latter by clapping their hands. ' Selecting New Dajtces. The meth ods of that grave and important body the American Association of Professors ot Dancing in determining the merits of newly invented steps, are very simple. This is the way they did it at their last meeting: Five of the 70 wise men were selected to act as judges, and tbejr duty was to pasB upon but one new dance. Alter this dance was presented, new judges were selected for the next one, and so on to the end. After the selection ot a committee, the discoverer, author and originator of the new dance mounted the stage, a pianist rattled off an appropriate air, and the other masters of dancing proceeded to tangle themselves up in the intricacies of the dance under the direction of the inventor. Atter the performance the dance was dis serted. If it resembled an old-timer it was killed, and the author was led ont in a state o collapse or remained in a state of indig nation. Bejections were many. The na tional society ol saltatorial matters evidently had the knee-breeches dignity in mind and refused to adopt any dances "but those be yond peradventnre those which might be danced with perfect propriety in parlor or ballroom and which were neither violent nor tiresome. The association put in four days of hard work, and selected lour round dances trom" the numerous ones presented. These were M. B. Gilbert's "L'KcIairei waitz. H.

Sew Theory of Seasickness That Sn&gests a Preventative. SEW DISCuYERItS AS TO THE H00N rr-RIrARED rOETHZDtSrATrn.J At the recent convention of the American Street Bailway Association at Buffalo, in many ways one ot the most important gath erings of the kind ever seen in tbis country, President Lowry congratulated the associa tion on the progress of which had been made in the work ot the association since its organization in 1882. He alluded to the fact that the United States Government had recognized the growing importance of city passenger traffic by incorporating in its census statistics for 1890 a report on street railways in cities of over 50,000 inhabitants. In this report 66 cities are included, and out of a total ot 3,150 miles of track possessed by them, 2,351 miles are operated by horses, 260 miles by electricity, 255 miles by cable and 221 miles by steam. In the smaller cities electricity js being generally adoi ted, and there are already in operation in cities and towns under 50,000 inhabitants about 1,600 miles of electric street railway. Mr. Lowrv added: I am so thoroughly convinced that elec tricity is the coming power for street rail ways (except heavy grade, where the cable is best suited), and that it will prove effect ive as a means of rapid transit lor cities, that I believe this is the last convention that will ever seriously consider horses tor the operation of street railwajs. When the people oi a city clearly understand the great benefits of rapid transit by electricity or other improved motive power over horses, they will demand that their city authorities grant snch rights as will enable street rail way companies to operate by the most im proved methods. Heretofore street railway securities have not been looked upon with avorhythe financial world. However, since they have been operated bv electricity, the financial men of the country are looking to its devel ment and application to street railways as an additional reliable security for the in vestment of savings and trust mndi. This should encourage street railway companies to give their various cities the most im proved and best possible service. Thev will not only please their patrons, but the invest ment will prove very profitable. If street railway companies do this, no better secur ity can be offered for the savings of the widow and orphan than a good street rail way bond in a thriving city. People have not vet begun to realize what an immensely important factor the increase of speed in city travel may become. It is estimated that had all the street railways in Boston been operated by electricity during the year 1889, it would "have resulted in a saving ol more than SI, 000,000 in money and an aggregate of 274 years' time to the patrons ot the roads, due solely to a 30 per cent increase in speed. It has been found that increasing the speed of the cars a given percentage inevitably increases the patron age in nearly the same ratio, while the oper ating expenses are increased by a very small traction of this percentage. An instance oi tbis has occurred at Davenport, la., where it has been lound, taking the record for one year, thit the total expense of operating five horse cars was $10,840, while five electric cars cost $11,270 to operate during the same time, or it cost to operate the same number of cars Zy4 per cent more by electricity than by horses. J. ne gross earnings ior ine xz months of the same equipments were: Horses, $15, 897; electricity, 823.670. It will thus be seen that although the operating expenses were increased 3J per cent where electricity was used, the earnings were increased very nearly 50 per cent, or, in other words, the substitution of electricity resulted in a net gain of more than 46 per cent, owing to the increased patronage induced by the im proved service. Best as a Medicine. A physician, writing of rest as a medicine, recommends a short nap in the middle of the day, for those who can take it, as a beneficial ad dition to the night's sleep. It divides the working time, gives the nervous system a fresh hold on lile and enables one to do more than make up for the time so occupied. A caution is given against the indulgence in too long a sleep at such a time, under a penalty of disagreeable relaxation. There has been mnch discussion regarding the alter-dinner nap, many believing it to be injurious, but it is, nevertheless, natural and wholesome. Improved Wood-Caevino 'Machih e. A wood-carving machine which possesses many radical improvements has been brought out. The machine is designed specially for nse inrfurniture lactones and in car, organ and piauo factories and other establishments where wood carving is done. It will carve four duplicate pieces anv length at one operatiou if not over 7J4 inches wide, or it will make two duplicate pieces any length if not overl5 inches wide, nnd if a greater width is desired, one piece can be carved of any length and from 15 to 30 inches wide. The bits can be handled conveniently and in any direction within an augli o 30. The top, or table, can be raised Or lowered to make thick or thin work, and will remain the proper height ior the operator; the table also rests upon slid ing ways, so that it can be adjusted ior the convenience ot the operator on different varieties of work. The driving pulley on the machine is 6 inches in diameter, with 3-inch face, and should make 1,400 to 1,500 revolutions per minute. Usefulness op India Eubbeb. The number of uses to which rnbber can be ap plied is constantly on the increase. The bnrnt rubber used for the final polishing of the gold lettering, etc, in the Government Printing Office, is simply India rnbber which has been subjected to a peculiar fire process that renders it very absorbent So remarkable are its powers of absorbtion that a piece the size of one's fingers will easily take up S5 worth of gold in iis pores. When such a piece ol rubber is loaded with all the gold it will fairly carry, it is sent, in com pany with others in the same condition, to the mint- to be assayed. Eubbei enters largely into the mauulacture of artificial flowers, considerable quantities of which are made in tbis country, nnd artificial limbs owe much of their xihility and adapta- uuuy in mis luuieriiii. it is me only bun stance that imitates the ankle action ot the bnman loot, and rubber hands are made so perfectly that many cripples are able to write by their use. The manu acture of smokeless powder has hitherto had most in jurious effects on the health ol those em ployed in irj-tjunow the men have been provided with rubber masks, which protect them- irom the fumes thrown off by the chemicals entering into the composition of the powder. One of the most admirable uses to which rubber has been put is for horseshoes; it is not only light and durable, but it markedly improves the hoof. Fibe-Besisting Bkicks. It is stated that an hotel has been built in Hamburg entirely of compressed wood as hard as iron, and rendered absolutely proof against both fire and the attacks ol insects by subjection to certain chemical processes. Iitranrous Cbayos A luminous crayon has been invented ior the purpose ot en abling lecturers to draw on the blackboard when the room is darkened for the use ol the lantern. The invention is likely to proTe of value not only to the lec turers who use a Itntera, but also (in an to those students who wish to The Electrician in War Lieutenant Fiske, in lecturing before the New York Electrical Societv, at Columbia College, de scribed the part that electricity would play in case ol an attack upon Hew York. Prom inent among the various appliances that would be called into immediate requisition would be the various systems of torpedoes, which would be launched from the prepar ing stations at Coney Island, Sandy Hook and elsewhere against the ironclads of the approachiog enemy. The question of ballooning, for observation and lor the dropping of explosives on the decks of the enemy, would be agitated anew over the question ot balloon propulsion by electric ity. Electric launclies,.arranged to carry torpedoes, would steal noiselessly out at nighton their errands of destruction. Elec tric picket boats of smaller size would scout the waters in pursuit of information or to convey dispatches numberless; electric sub marine boats would spring into being and, secure from detection below the suraceof the sea, they would carry enough explosives to utterly destroy the proudest war ship of the world". It being apparent that the reg ular army and. navy of the country would be unable, in tbeeventof a sudden war, to handle all the electrical wore: that would certainly be thrown on them, Lieutenant Fiske proposes the ibrmatiou or- a corps of naval and military electricians to assist the regular army and the navy in its worki Such a corps might exist in every principal seaport town on the coast. The Polymetee. An instrument termed a "polymeter" is now used for meas uring and regulating the requisite quantity of moisture, or so-called humidity oi the at mosphere. It is designed also to determine the vapor pressure and temperature. It is of special value in technical industrie. being largely used in cotton mills and paper starch acmries, as well as in hospitals and private honses. New Theokt op Seasickness. A new theory of seasickness has been recently offeied by Monsienr Rochet. Accepting the view that the symptoms are those of cere bral anaemia, he accounts lor this ausmia by the disorder brought into muscular coo tractions through not being used to such sudden movements as" those of vessels. Mon sieur Rochet's advice is,not to look to us thetius, soothing drugs, etc., for relief, but rather to muscular excitant3,.and, above all, to seek in voluntary movements a compensa tion for the reflex movements which are not produced. He recommends strychnine, veratrine, ergot of rye and drinks charged with carbonic acid. Spouting Cowls foe Steam Boilers. A novel appliance has been introduced in Eugland in the shape of a spouting cowl for promoting active water circulation in steam boilers fitted with Galloway tubes. The cowl is fixed on the top of each Galloway tube, without, however, interfering with the structure of the boiler. The cowl cuts off the local movement and causes the circu lation to become general. A certain quantity ol water escapes in a thin stream Irom the lips of the cowl, and there are special facilitiejjfor.the disengaging of the steam carried' up " in the .water. The amount of primiug is thus materially dim ished, aad the uniiarin. temperature secured in all parts ol 'the boiler conduces to its preservation and greatly diminishes the deposition ol scale. In addition to these advantages, the indirect effects of this ap pliance are economy of fuel, economy of time, reduction ot the cost oi repairs, and increased length of liie of the boiler. Value op Astbonoht in Numismat ics Dr. A. Vercoutre points out that a knowledge of the star maps may be a great help to the numismatist. Many of the coins and medals of the Roman Republic have the stars depieted in their proper positions relatively, and consequently enable the numismatist to decide tne date of the coin, and also help the astronomer to form some idea ot the proper motions of the stars. Progress of A SjIronomiual Pho tography. Prof. Holden gives an inter esting account of the photographic appara tus, and the work done in astronomical photography at the Lick Observatory. He states that the negatives t iken there bear easily an enlargement of 570 diameters, and even double that amount. From an exam ination of the best pictures taken at the ob servatory Pro'. Holden finds that parallel walls on the moon's suiface, whose tops are not more than 200 yams or so in width, and which are not more than 1,000 or 1,200 yards apart, are plainly visible. There is no doubt that enlarged photographs are ca pable ol affording more information regard ing the moon's surface than can be gained by years ot diligent observation, and when the larger lenses now found 'necessary are brought into use, marvelous strides in tbis direction may be looked .or. Tubular Bandages. The treatment of various lorms ot disease by surface appli cations o hot and cold water has been lound to be exceedingly success ul. An adapta tion of this ideainwhich the water in no way conies in contact with the person, but at the same time is made the vehicle by which the heat and cold are applied on the affected parts is a new tubular batidugp. It is made in fonr pirts, the first being a head bandage so arranged that a continuous stream of hot or cold water can be made to encircle the head and flow away, being all tne ume encmseu in me tnouiar vessel. Other bandages are specially adapted lor throat and spinal trouble. The Storm King. Captain Jorgensen. the inventor and navigator of the lifeboat Storm King, which has just made the voy age Irom England to Australia, stated in Melbourne that his invention was especially designed to be of service when vessels sank without warning "through collision, or in any case of sudden panic. It was impossi ble in large vessels carrying 1,000 or so, to have boats sufficient to accommodate the whole, and it ihere were, there would not be sailors enough to man" and navigate them. Such a vessel, however, could carry boats ready pieced together, after the Storm Kinir pattern, sufficient to arcomturdate 600 or 700 peoide.-Jand other separate sections conld be stowel in diflerent parts ot the ship. The value of these sections lay in the fact that they did not need to be put together ip order to be used. Each section would form a perfeit life-saving apparatus, and although it would not be possible 'to " navigate them until they were- joined together, each would contain water and provisions ior 14 days, and would suffice to " preserve life lor that period. SPECULATION OVEB EUTHS. Strange Story Surrounding the Discovery of . a Fortified City. Philadelphia Becord.l The strange story, told on good authority, or the ruins of a great fortified city, built of dressed granite blocks, found on the Mashonaland plateau, ihT. South Africa, has given m rise to a great deal ol curious speculation, for its historv is wholly unknown. Many of the walls are completely covered by the dense jungle and very old trees grow-on the top of the rains. If the city or lort was built by na tives, it must have"beeninremote periods of time, when there was a higher civilization than now; but it is just possible that the fort was constrnoted uuder the direction of early Portuguese explorers, and by the aid ol cheap slave lalior. Only a superficial view has been made of the ruins, but light may be thrown on the mystery when the houses themselves have been explored. Light is being rapidly turned on to the Dark Continent, and the stories that come from it are as Interesting as those sent to Europe irom this country 300 to 400 years ago. Then, however, the oi ws was not widely disseminated. Now every one who chooses can learn from day to day what Is going on in Afrioa si in other parti of the world. other form) take notes. ELECriqC CURRENTS. Their Nature iTade Clear by the Ac tion of Heat on a Bod. RECOGNIZED ONLY BY EFFECTS Units of Measurement Used in Speaking of the Condition. THEIR RELATION TO EACH 01 HER IWKITTES FOB THE DISPATCH. I Take a brass rod, say a yard long, give it a thin coating of wax, then place the rod on two supports (window panes turned on edge aie good), and underoneendplacea lighted Buusen burner; the coating of wax will be gin to jnelt, first directly over the flame, then lurther and further away. We can see the heat travel the entire length of the bar, till at last the entire bar is warm and the wax all melted. It we call that end of the bar under which we place the burner North, and the other end South, we would naturally say that the heat had traveled from the north end to the south end, and, as a matter of convenience, such language wonld be perfectly correct, but as a matter of fact, nothing has traveled irom one end otthebar to the other, for, if there had, this thing would, most likely, have dropped off at the south end, or the south end wonld at least have been heavier since 'bis thing got there, but no, nothing dropped off, and the end is not any heavier than it was betore .the heat crept over there. THE PHILOSOPHY OP HEAT. 'Heat is a condition ot things and cot a material thing. If a body oi matter is warm its molecules or small invisible particles, of wnu-n it is snpposed to be composed, are in rapid motion, and this rapid motion gives to the touch the sensation called heat It one body is warmer than another its mole cules are supposed to be in more rapid mo tion than those of the other I. a body is warmer at one time than it is at another, its molicules or particles are supposed to have been in more rapid motion the first time than the last, and this motion or condition ot the body gives to the touch the sensation we call heat. " uow' reerr'n2 to onr rd again, nothing that we can see, weigh or hold in our hands, has traveled from one end of the rod to the other. It is simply that the condi tion of the rod has been changed, and this change began at one end and crept over to the other. And we naturally say in ordi nary conversation that "the heat crept irom the north end to the south," and in saying this imply both an advancing motiou or flow and a direction, but as a matter of lact, we have just seen that there is no ad vancing motion or flow, but there is a direc tion, for we can see this with our eyes and we say it is irom north to south. KNOWN BT ITS EFFECTS. But after all it is only the effect that we see. Suppose that we could not see the Bunsen burner, and we simply had a por tion ol the rod before us, we would still know, by the gradual melting away of the wax from one end toward- the other, that beat was, being applied at oue end, and not only tbis, we could go lur ther aud lorm a rong'n estimate of the inten sity of the heat by the rapidity with which tne wix melted off. Or better still, if we should grasp the rod by the hand we would be able to form a very good idea o! what was going on. In other words without being able to see anything butthis wax-coated rod, we can, by observation and by noticing va rious effects, tell a great deal about what is going on there. Heat, therefore, is the name given to a condition ot thingstand we recognize this condition ol things called heat by its effects. Jf we see ice melting we say that there is a little heat there, because 'the condition of the iestis being changed, -and in-the melting rwe notice the familiar effect ol heat. But i we see iron melting we say there is ereat heat, for we know by experience that it takes great heat to melt the metals. Thus again, by the effect of heat we not only recognize its presence without be able to see it, but we also have a means ot comparison by observing its different effects. ANOTHEE KIND OF CUEEENT. And so it is with electricity. AVe often hear the expression "electric current" and 'electric fluid," but these are simply con venient names given to a certain condition ot things. Just as we say that the heat crept along the brass rod becanse it had that appearance', so we say there is a current of electricity in a wire when we notice a certain familiar appearance or effect evidently caused by the condition of the wire. Now, some ot these tff cts are such that there ap pears to be a flow or currentof something in the wire. ' For example, we can start a current of electricity in at one end of a wire and measure the time it takes to reach the other end. What more natural inference then than to think that electricity is a current or something flowing. But as with the heat and rod, nothing came out at the other end, so it is with the electric current, nothing comes nut at the otherend of the wire. In tact, nobody has been able to weigh electricity or see it or hold it in the hands. In other word-, it is not a tangible thing, but a condition ot things, a form of energy that we call elec tricity. But because it; like the heat in a rod, acts as though it could flow or travel, ue use the convenient term "electric cur rent;" and although there is no actual cur rent, yet, as with the heat and rod, so here, there is a direction, and this direction as well as different amounts of electricity, aud in fact its very presence, are all known and calculated FEOM FAMILIAB EFFECTS, and the observations made on them. For example, if we dip the two pohsol an elec tric circuit into a pail of water, the elec tricity will decompose the water. We thus at once recognize the presence of an electric current. But urther it we repeat this opera tion and find that in the second experiment twice as much water was decomposed as fn the first, we know then by making a com parison of the effects of electricity that there was twice as much enrrent in the second case as in the first, provided the time that the current was allowed to act on the water was the same in each case. Thus without seeing or bearing or touching anything we are able to recognize the presence of elec tricity by its well-known effects, and by comparing the effects ' we are enabled to make relative measurements. However, in order to be able to talk about such measurements and make practical use of them we mnstbave standard nnitsof measurement to which we can refer all other measurements just as in liquid measure, ior example, We must have some -standard unit of measure,-like the quart.by which we can compare all other liquid measures or vessels. Thus we can say that a certain bucket holds so many quarts, but we might ju-t aswell have takeu tbis bucket and called it the unit; then we would compare other vessels with the "bucket" and say, for ex imple, that a certain tub holds so many "buckets." MEASUBING ELECTEIO CUREENTS. Aud so with electricity we have standard units oi measurement by which, all other measurements can be compared, arid in this way we are enabled to converse and exchange intelligent ideas on the observed effects of the electric current. There are three stand ard units, viz., the volt, unit of pressnre; the ampere, unit of quantity, and the ohm, unit ot resistance. Aud from these all the others are derived, as lor example the Watt, or unit ol energy, which equals, one bolt multiplied by oue ampere. The legal ohm or unit of resistance, and to which all other resistances are compared, is the resistance ot a column oi pure mer cury 106 centimeters long, 1 square milli meter in sectional area, at a temperature of 0 C (zero degrees Centegrade). The volt or unit ot pressure, is tne pressure tnat will force one' ampere of current through one Lohm of reiiitanck-ud the ampere or unitjjsrholesale, according to quality. of quantity-is the amount of current that one volt will force through one ohm of re EELATION OF THE UNITS. And further, it has been found that the following law, or relation, exists between these three uuits, viz: The pressure in volts is always equal to the quantity in amperes multiplied Dy the resistance in ohms, from which, if any trio oi the above quanti ties are known, the third can alnays be calculated. The ampere or unit ol current is established by the amount of copper it will deposit in a copper bath (voltameter) in a'given time and under given conditions. Thus the-unit ampere isthat amount of cur rent which will deposit 0.00032959 gramme of copper per second. The needed appar atus and conditions for an accurate deter mination of this unit cm be found in al most any text book on the electric current. We have tnus established two out oi the three inndamental units o electricity, and fiom the above law culled Ohm's Law we can easily determine the third. Sciee Facias. THE ELECTRIC WORLD. New Applications of the Mysterious Current to Every-Day life. (WKItTFN TOR TUS DISPATCH. I A new adaptation of electricity has been made by a large publishing house. In the office of the superintendent are ten electric lamps, each having its distinctive color, Men are con nected bymeans of wires with the automatic counting machines on the ten large printing presses located in an adjoining building. When the presses are in operation the circuit is opened and closed by the working of the count ing machines, causing quirk flashing of light in the lamp Thus every t-heet ot paper printed In the establishment telegraphs its record to the office) where the operation of each machine can be seen and its speed or delay noted. An interesting pmbt in this connection Is that the speed ot the large perfecting press Is so great that it was found necessary to record each two sheets printed instead ot single sheets, and even then the flashes of Its lamps are almost continuous in appearance, showing that while the press Is not quite as quick as lightning, it is too fast for the eye to follow. Managers of large est.iblishments.uho wish to be able to see me operation or their machinery while worK ing at their desks, are likely to avail them selves of modifications of tbis new departure. . Attention has been drawn to the advisa bility of the adoption of early remedial meas ures by those who are suffering from the effects of a too long exposure to strong electric lights The "tired" sensation in the optic nerve, whlcn such exposnre causes, and the local inflamma tion which accompanies it, are both due to the fact that that the luminous waves proceeding from a powerful electric lamp aie not of very great intensity. The general symptoms in duced in the eyes of people who have been ex posed to the glare of unprotected lamps for too long a time are: (1) Transient irritability of the retina; (2) local Inflammation: (3) tears and "flashing" of light before the eye; (4) incipient paralysis of the eye. Usually people experi ence sensations which are analogous lo those which are felt when panicles of foreign mat ter are present beneath the eyelid. In order to prevent the sight being permanently injured, it i necessary to adopt hygienic shades, hough these do not act thoroughly in reducing the in tensity of the luminous waves. Rest must be sought, and the pain relieved dv the applica tion ot cold water compresses. When the pain is almost unbearable a calamity frequently suffered by those who h ive bean exposed for many hours a day to the glare of powerful lamps a medical man may relieve it by the in jection of cocaine and atropine. Tho French call this peculiar malady "electrical sun stroke." .. AN Interesting exhibition was given in the central station of the electric light company in Melbourne recently. A supper was served, all the viands of which were cooked by electricity. Tne culinary operations included the grilling ot beefsteaks, the making of toast and the boil ing of water. Clocks are being made for the towers of churches aud public builings which, instead of having an illuminated dial with dark hands, have a darn face with enormous pointers of light. These pointers are made ot glass, over an lion frame, and are rendered visible for miles by incandescent lights, whicb give them the appearance of slender white rods of Are. - A patent has been granted for an electrical drill for oil wells. The device consists of a series of motors in tandem, connected in snch a way as tomake one motor. The design has been to get the power within a six-inch diame ter, so that the entire mecbanixn, which much resembles a common boiler, can be lowered in the well, and too power can oe applied at the bottom. The drill bits are firmly fastened on the rod, which is worked rapidly in and nut of a cylinder, after the manner of a piston rod. . The primary battery bas been applied to the propulsion of invalid chairs in England. A strong chair, weighing about 200 pounds, is fitted with a battery at the back of the seat, and can be peeden up to about five miles an hour. As it is calculated that the cost of maintenance of the battery does not exceed 4 cents per honr, and as no renewal would be required during an ordinary da's use, the economy of this mode of propulsion for invalids is apparent. These are many indications tbatbefore long the electric light will be the only illuminant employed on railway trains. An important step bas been taken by the Russian Govern ment, which has decided that all the cars shall be lighted by toe electric light in future. CUBING C0NSTJMPTI0H. A Shop Experience That Points to Hydro cyanic Acid as the IJesult. The paper read by Koch at the Berlin congress on the treatment of consumption, of which I spoke at some length in one of my recent articles, says a writer in the Paris edition of the New York Herald, gives a certain value to a publication by Jir. KeuterJ and I think it quite probable that it may become the starting poiu't of a new treat ment of tuberculosis. Mr. lleuter has been for several years director of a factory in which all sorts ot metal objects are manu'actnred. In someot the workrooms the gilding and slivering is done by the galvanoplastic process. Mr. lleuter noticed that among the workmen employed in this part ol the factory those who had the appearance ot consumptives and who presented svmplnms of tuberculosis were considerably benefited by their work. that their cough diminished as well as the expectoration and dvspnai, while they in creased in weight He noticed, furthermore, .that the condition of these patients when they pa.'sed iuto other parts ol the factory grew worse again, although their new occu pation rMgbt be less fatiguing than the former one. .Under these conditions the question arose wliether the improvement noticed during their sojourn in the rooms given up to the galvanoplastic process had not some rela tion with the escape of hydrocyanic acid from the surface of the apparatus. Mr. lleuter is convinced that this is the true explanation- It might be feared that living dn that way in an atmosphere con taining an appreciable amount of .hydro cyanic acid would give rise to symptoms oi chronic' Doisoning,but after having ex amined over 100 persons who had been oc cupied in the above mentioned rooms during the last 30 years it was found that this apprehension was without foundation.

This year, how ever, only 25 bushels of New York nuts have been brought to market. This famine has created a market' here for Southern grown chestnuts, and the supply irom Vir ginia and neighboring States was so large that the NewYark market was almost flooded a few days ago.

MTSTEEI- OP THE DUKITE SNAKE rwErmu roif the pisrATCR.i A trip across the inland deserts of Aus tralia is interesting, but toilsome and dan gerous. Port Angusta, at the headL of Spencer Gnlf, in South Australia, is the starting point for two thnrougblares. One by the northeast to the great grazing downs of inner Queensland, oue by the north through dry valleys and across dusty mountains, hotter with every mile of north ing until it dips into the steaming jungles of the northern coast, close upon the equator, which seems hotter there than anywhere else within its torrid span. The Queensland road marks its track be yond mistaking in the bleaching bones of cattle that have talleu by the wayside, The great Northern road is marked "by a light thread oi wire strung overhead, lor it is the course of the overland telegraph, which links Australia and New Zealand with the world's news and daily cares. A railway is now building along this route and the work of construction is prosecuted from either end so rapidly that it will not be long before luxurious travel is possible over what is now the path of toil. TOBACCO A NECESSITY. The traveler's b iggage must be cut down to what can be carried in saddle bags. The wise traveler adopts the theory that a suf ficient snpply ol tobacco must be carried and as much of other things as space per mits. It is the only currency o the bush a good quality lor the white men to be met, rank blackstrap for theaborigiuels. Of course we took the new railroad as far as it was built. This was Baltana, a typi cal track town, which retained one of tne mushroom growths of the days when the Pacific roads were building. Here the real journey began aud the means of locomotion was the camel. It is barely possible that there exists some locomotive agent oue de gree more intolerable than the camel. If so it is not known. The wretched beast main tains a distiuct gait in each of its lour legs, it swings its head with the motions ot still a filth mode of progression, and the roll of its body is a resultant oi all three ar.d yet other lorces not clearly to be identified. Then the camel may crane his neck aud bite you and the general air ot wickedness of the Afghan driver keep you in suspense. BOTH ABE IMPORTATIONS. Camels and Afghans were imported by Sir Thomas Elder to develop his run, which begins at Baltaua aud extends far into the remote interior. Camels curry one over the salt desert where horses could not live and deposit the way.arer at the station at TJni born, where is a well, a shanty aud a col lection of horses which have more vicious tricks than any herd o. the equine sort ever bred to mischief and depravity. The most deceit ul of the herd was here acquired aud behaved lor a hundred miles beautifully and lor the next thousand miles fiendishly, until an iniquitous disposition killed him in the desert. Alter the new railroad, the camel, the horse, no more experiments offered any in ducements, and the remaining 500 miles were penormed with those only reliable ageuts of locomotion, one's own leet and legs; and these Ioug miles were the most en joyed. So much for the manner of making the journey. THE TELEGBAPH -WISE. The road is no road, it is not even a trail to sight less keen than the black fellow's eye. The plain direction is never to lose sight of the telegraph wire which sags be tween distant poles of iron pipe so slender that a mile away they can hardly be dis cerned. Following the faint shadow of the line upon the sand, one comes to springs or pools oi filthy water at long tintervals, and it is necessary to take the inland trip in Australia to discover how filthy water can be and yet tie greedily lapped un to quench tbint At intervals of about 159 miles are found the relay stations ot the telegraph, uni formly neat structures ol stone, where two men live in lonely company, watching that their wires work uninterruptedly, reporting once a day to the end ot the line that they are well, and .or the rest of the time listen ing to the click of the cipher which hides roni them the news of the world, which might alleviate the intolerable monotony of their lile. Sometimes there comes a break in the wire, and that breakb the mouutonv. lor it may mean that some starving wanderer has taken that means of summoning succor. NATIVES PEAK THE WIBE. A simple galvanometer test suffices to fix the exact position of the brea, and with his kit of repairing tools the operator carries food and drink to restore a lamished man There is no chance that it is a trick ot the wild natives, ior oue and all they dread the mysterious wire with a great lear and never dare to go beneath it except in the darkness ol night. In such gradual journeying the scenery changes but slowly. The first third of the way lies over deceptive plains which seem level and yet strangely bar the view with their unnoticed elevations. This is the land ol baked c'ay, of bine bush aud salt bush and the thorny spiniiex. Tbe-second third ot the journey is among mountains and rolling bills. Here are uogreat heights and no deep valleys, yet the change is an agreeable one; water begins to be more plen tiful and of a better quality; there are even traces ol rain in the shape of green vegeta tion. There are drv stretches between the ranges, bnt lor the first time clouds are seen in the sky with promise of moisture, a prom ise which every northward step brings nearer realization. X MYTHICAL SEBPEJIT. The final third of the way lies within the tropics, showers begin to come and soon de velop into down-ponrs. The dry plain changes to the rank sogginess of marsh land, there are suggestions ot alligators, there are mosquitoes and all manner of venemous flie. At last Palmerston is reached on the Bhore of Port Darwin, which opens into the Indian Ocean. The journey is over, and at the end no one thinks it in any way re markable. Nowbere has there been a sign of the Da kits snake, which alone could make it worth while to take such a trip. All believj in it. All are convinced that the man who kills one Dnkite snake must immediately kill its mate or be relentlessly bunted down and slain by the bereaved serpent. His habitat is loosely said to be up somewhere on the line of the telegraph. Three months' search tailed to discover even a single Dukite; faith in this serpent has gone with shattered taith in many another serpent who has proved himself a myth. His existence is confined to the musical verse of John Boyle O'Keilly, who heard of the Dukite when he wore fet ters in the bush. "William Chuechill. . COFFEE IS A FE0PHET.

Tea is not a lood. By a "food" one means any substance which can contribute directly to the nutrition of the body. Fat is a food in this sense: so is sngar, and so is starch. Minerals such as potash, Iron, lime, and so forth are also foods, becanse they assist in building up the natural structure of onr frames. Again, the nitrogenous substances albumen and casein and gluten, and tha like are foods, because they enter inti mately into the composition ot the most vital parts of animals. So that the list I have just given nitrogenous matters, fats, starches and sugars, and, finally, water in cludes really all our necessities in the way oi nutriment. It is true, of course, that the most of ths things we eat are in themselves combina tions of "foods." Be"f is -not-one food, bnt tour at least water, nitrogenous matters, fat and minerals. Let the chemist analyze tea ior ns. and tell ns of what things it consists. Here is his reply: Minerals, leaf-debris, tbs merest traces ot starch, and, finally, certain important bodies known as alkaloids, among wiich theine and caffein stand out promt nently. The theine and caflein are un doubtedly nerve stimulants in a very direct sense; aud the reviving effects ot a cup of tea are certainly dne to the presence oi these alkaloids. Have yon studied the nutrition of mill hands, milliners, and the great army of women-lolk who labor and toil in onr great centers of population? I. not, just think of the enormous nutritive waste, and of the terrible error in dietetic, which everyday' represents, when you find the working classes (and other classes as well) living chiefly on tea and bread. Ont of tea you'ean get practically no energy or force where with to do work. Ask any physician who labors in dispensary practice what he knows of the effects o nuder-uutrition as repre sented by tea (used as a "ood), and you will oe surprised to hear of the amount of dys pepsia lor which tea-drinking' is responsi ble. Take, away tea, and what is left then for the working man? I have no difficulty in replying cocoa. This last-is a true food. It contains starch and lat and sugar, along with nitrogenous matter, and also a stimu lating principle. A cup of tea is no fit breakfast or any man; bnt a enp of cocoa, with bread and butter, is really a meal on which the laborer may fitly begin the toif of the day. - The Austrian "Way.
