We issuewith_this_ninxiber of our jnarnal a supplemental sheet for the purpose of calling the attention of our readers to the works and products of the celebrated Philadelphia House of Harrison Brothers & Co., who have op od a Branch plaice in Now York, at No. 1.6 Burling Slip, S. E. corn of Water Street. and in Chicago,' with Rockwood & Blocki; No. 192 Lake st. and No. 20 Wells st. Teo writer of this article has been privileged to visit their exten sive works at Gray's Ferry and .lieneington in Philadelphia, and .11:om personal observation and data courteously furnished by the oroprietors, has prepared this sketch, which we trust will be found interesting to the general reader, as well as to those concerned as dealers or consumers in the various important products of this iirm. It will not be inappropriate, before speaking of the Kensington and the Gray's Ferry Works, to make some ' briof mention of John Harrison, who built the Kensington Laboratory and founded the present house of Harrison Brothers le Co. John. Harrison having received a scientific oduoation .in this country, finished his studies under John Priestly, the celebrated chemist, in England. He was from the first much 'interested in practical' ohemistry, and was impreesod with the belief that many productS whiob we had alwbys precured Iftom abroad could be manufactured successfully hero, and thus' accomplish the two-fold advantage of rendering us less dependent upon Great BKitian, and opening up a new and important source of national wealth. . Prominent among those, and of incalculable value in the Lilts, --Sulphuri.e..A.cisl or Oil Vitriol, whirl has been not inaptly termed the king of acids, arrested his a entiOn t riiiiiiit - tillyTtirerefore r hi: first effort was in the production-of this important article, and as early he 1793 ho-met with marked success. Looking back through the lengthening vista of years to the dim twilight of those remote days of American manufacture, We contemplate this enterprising pioneer advancing with no uncertain steps towards the assured success which his exertions merited, and we can appreciate in some measure the feelings with which his successors may be sup posed to cherish his memory, and the satisfaction with which they may justly regard the Substantial supel'structure which has been retired upon a foundation so ample andsecure. In this connection we quote a short extract from a letter, ad , dresseein November, 1808, by John llurrison to his_friend`plunnas Jefferson, the President of the United States. At-this time it will lie seen that he_was largely engaged in the manufacture of various chemicals at the Kensington Works, and the letter is extremely in- -teresting, as it gives in _his_own _words some_sketch_of_his-early career,: "In the years 1793-4, I commenced a series of experinients for the preparation of Sulphuric, Nitric and Muriatic Acids on, a practical scale. In this attempt I succeeded so far as to prepare them to the utmost perfection; but the high - price of the raw_ma lerials,- (Sulphur and Saltpetre) the want of sufficient - dem - a - All; and the easy intercourse with Great Britian, froit whence we ob • tained our supplies, occasioned me to abandon the undertaking, though at considerable loss; and from that time till 1804 I con- tinuedin ray profession as chemist, content with preparing only such of them as were necessary for the supply of my immediate customers. _At this period, believing the consumption of the United States to bO t sufficient foi: the support of the undertaking, I relin antsbedmy business and devoted' the whole of my :attention to this importhnt subject. t In order to perform it with effect both capital and enterprise were requisite.) I employed $5OOO in the construction of apparatus alone, which, had 1 failed in my en deavors, would not have produced me 82000; but I succeeded. It became necessary, of course, to increase-the works fel the purpose of doing business on a large scale; because I could not expect the' support of the venders or consumers of tlrse articles unless I could give them assurances ormy ability to supply all their wants. I consequently enlarged them to such an extent as-I believe to bo equal to the supply of the whole of the United States, att ,I Lave never yet had a demand for more than one-fourth of the quantity lam capable of producing. I have since added to my establish ment the different preparations of Mercury, AntitUti . n):, Copper and many other articles of lesser . consequew3e, and have employed - aEravapital 840,3002? ' From that time (1804) the work, went on successfully. The-- Acid depr"tment, however, was once entirely destroyed (it was Supposed by an incendiary,)-but immediately rebuilt upon .a larger scale,: To the products already named was added, shortly after.' ~ wards, the corrosion on an extensive scale of White Load, of which . he was the second to manufacture in this country. Pyroligneons or Acetic Acid apparatus was next constructed - , and front that time, either by; him or his successors, Harrison B'rothers, the works have been increased as fasCas the trade demanded for the produotionof Colors, Rod Lead, Litharge, White and Brown Sugar of Lead, Alum, Copperas, Acetate of Limo, and of chemicals.. - We close this preface with extracts from Freedley's "Philadel- , 'phia," a work of standard excellence and authority, devoted to the interests of that city and its manufactures: , "The manufacture oLehomicals in the . f :United States may he said- to date from the war of 1812.1 The commercial restrictions "that Precededthat war caused such a scarcity and dearnesi of Chemicals that the preparation of:the more,prominent articles offered an attractive field for enterprise. Previous to that period, however, a Philadelphian had established successfully a manufac tory of 'Sulphuric Acid?this was Mr. John Harrison, the first sue:: coastal manufacturer of Oil Vitriol in the United States, and the founder of the well known house of Harrison Brothers & Co., the present proprietors of the 'Kensington' and `Gray's Ferry' Chem cal, 'White Lead and COlor establishments.

On the completion of their Gray's Ferry Works, now • rapidly approaching perfection,. they will have the facilities for producing about 4000 tons per anmim, which we believe exceeds the abilities of any establish ment in this country or Europe. The productions at Gray's Ferry will be in addition to those made at Kensington: In connec tion _With_the; Lead Works is the Color Department, when) * they Manufacture extensively Vermilions, Carmines, Wood-lakes, Blues, ,Yellows, Greens, Dry BlaCks, &c., &c.

KENSINGTON • •, B. • :J 4 CHEMICAL WORKS. We now proceed to give some account of the oldest of the two establishments of this firm, namely, the Kensington Work; and of the leading products which for three-quarters of a century have been here prepared, and which, are recognized a'.:k.s„Aandards in point of quality. We must premise, however, that our limits will admit, only Of a cursory sketch, touching upon the more kaliont points which met our observation while treading the numerous, avenues intersecting the extended grounds of the Kensington en closure, and passing .through its Series of buildings, the number aAd:extiiiit of which may be inferred from; the fact that the aggro- - gate roofage covers a total area of 'three and three-quarters aeres." The first_step in the manufacture of Carbonate. of Load consists in melting pig lead (of that quality which is deemed the best for t e pro nation of VliitoLead) in-a-large-cast iron boiler or-kettlei firmly set in masonry.. The melted - metal, sluiced off ( through an aperture - at the bitse; is fed by a - trOugh into a series of iron imnil6 revolying on an endless chain; the lead is thus cast into tho firm . of grates, :technically called buckles, weighing about 4 pound each; and by -means-of-this arrangement-of revolving-mouldti-as much can be done in nn hour as in an entire day by the old Method of casting by hand. These buckles, as they fall from the moulds, aro transferred by an attendant to a 'heap at the further end of the foundry, to be convoyed thence-to ranges of buildings called • STACKS OR BEDS, occupying about the whole of -the lower part of the yard, where may be found Load in the various stages of corrosion, all tightly fastened up; and to be opened and emptied in turn, as the process of carbonization is perfected. Some account of the - . may here be fitly introduced. Those consist of frame structures,— roofed in, and provided with double walls, the space between which is loaded with tan. .In front.of each a , door rises the whole height of the stack, to Ihcilitate Ito introduotjffr-of the materials, but whit:ll is closed by boards placed cwwise tis the several beds are erected. The method of 'ratting in a bed is as follows :—A layer of. tan is spread evenly upon the bottom. On this aro placed, strong ealqben pots,' which aro about 10 to 12 inches deep, and say six inches in. diameter Lit the top, each glazed within, and moderately tapering towards the base. Within thesp pots, at a sufficient height from the bottom, project ledges or nipples,'upon Which aro tiered the buckles of lead. In each pot is deposited beneath these ,buckle:3 about a pint of acetic acid of proper strength. Over the first tier of pots thus prepared boards aro placed, find on therie' a layer of tan, fidlowed by a second tier of.pots, and this process is comb:tied until the stack Is filled, when it is tightly shut up and• the chemical—Trio:is take place. At the end of a period varying from 10 toll weeks; the beds are opened, amt .- the, metallic Lead, 'transformed into a beautifully whit& Carbonate .and much . augmented in hulk; is taken to the arid passed through a long revolving screen, slightly inclined, thi•otigh the meshes of which the Cnrbonitte fulls like snow into bins prepared for, its reception; while the Blue Load, which the beds hnd failed to convert into Carbonate, is discharged at the lower end into a' separate bin. It wore tedious minutely to follow the various succeeding manipulations, and we will merely remark that the ,Carbonate, after being ground in burr-stone mills, and floated through various rectangular cisterns for purposes of leviga tion, &0., is finally gathered and spread' in the form of pulp upon immense drying-pans in the • Deprived here of its water, the product of these manifold pro cases assumes the shape of Pure Dry White Lead of Commerce. The process described above is knoWn as the Dutch Method, and has been found to produce this invaluable pigment in its utmost perfection.. Up to this time no pigment lies boon discovered to take the place of pure White Lead, and no mode of manufacture, except as above described, has produced-a good and wearing paint. NoW and quick processes" !have been , invorited,t. but all - have proved failures and of short lifetiiii - prodtict pleasing the eye, but lacking body or opacity, and durability. The Carbonate slowly - formed in beds is more finely divided and presents a larger number of `Parti elefi in a given bulk than by any other Ametlio ‘ d..

It is dried, and`then ground and calcined in reverberatory furnaces. When thoroughly calcined and purified it is next, while hot, digested for some hours in immense vats of dilute Oil Vitriol. It . is then washed with water, and concentrated—sulphate of ammonia having been pre viously introduced—in suitabien.iparatus.. It is next, washed again and freed from any remaining impurities, and- being thus double refined and then boiled by steam in a Roching Kettle to a high 1- ilereo of concentration, it is finally transferred to the crystallizing tubs. These are about eight foot high, and nititre of strong staves; which are go put together in sections as to be easily separated. At the end of eight or ton days,.these actions being removed, a cylin drical mass of apparently solid.- ; alum is revealed. This being pierced near the bottom, the mother-water at the centre flows off along the sloping floor into vast leaden subterranean cisterns - - whence it is subsequently pumped and variously utilized. Those '"Pillars of Salt," or, rather, ,of Ammonia Alum, as the product ,is, called in commerce (it will be perceived from this very cursory and imperfect sketch of its manufacture -that the article may be, more accurately termed a double sulphate of Alumina "and Ammo nia); these hollow cylinders of Alum, when pierced and cleft, are suffiito stand tilFtho mdttWliquor hasu 7 tffilly drier 1 ott, and aro th'en broken up and barreled for i the market.

This article is largely used by Calico Printers in thflireparation of the mordant for their dyes, (for which purpose freedom from iron is essential,) by paper and color makers, by tanners, &c., and in medicine. A very ingenious and important use to which Alum has been -put deserves special mention in this connection : we refer to the Alum and Dry Plaster Safes, made by Marvin & Co., at• their ex tensive'works in thii . city; a combination for which a patent has been secured. Dry Plaster is an excellent nOn-conductor of heat. Alum, which is broken up and mixed with .the plaster in these safes; contains a very large per centago of water of crystallization, which is liberated at 'a temperature somewhat above 212°, and affords thus..the most efficient protection - to tlie cenTentg ortt safe that has ever been devised. About 25 to 30 barrels of Alum per week are used by Marvin & Co. in the manufacture of their safes. COPPERAS OR SULPHATE OF IRON Contiguous to thd . Aliim grounds stand the Copperas Works. Much of the Copperas found in. the market is of interier quality, being mado from refuse liquors, such as the„spent acid from coal oil' refineries and other impure materials: The - article- produced at these - Works is made from iron turnings and shavings, acted upon by dilute Oil Vitriol ; this solution is concentrated by evapor ation and then transferred to _ a . . series of crystallizing tanks.

To make those oxides pig load, selected 'l:,om the product of the purest ores, is thrown upon the spacious hearth or bed of largo reverberatory furnaces, of which there are four with capacity to produce over a ton a day in each. The Lead is melted by fires playing over it, and is kept constantly agitated to expose new surfaces to the air which imparts oxygol to the metal. (At the Gray's Ferry Works an improvement in the oxidizing of lead is in use, which will be described hereafter.) This operation is continued till nearly the whole of the lead is oxi dized and a yellowish powder of oxide results, which is called lifassicot. - This is taken out, ground and washed, and during the process of levigation the oxidized particles 'l.)e:slg floated off from. the blue or metallic lead which has escaped oxidation are put back as pulp into the furnaces, dried; and then pulverized in burr-stone mills. This-product is Litharge. By subjecting the pulp to the action of the furnaces for a longer- time it absorbs more oxygen, asAnines, a bright red him, and-is-converted into Red Lead, which when properly powdered is ready for the market. . It is a specialty' with this establishment to prepare these oxides for Potters' uses, and for Varnish, Glass and Rubber manufacturef.s. Their trade in these oxides,- is' more extensive than that of any other firm in the country, and their brands readily command I to cent per pound (anti ii :some districts by - a difference in freight, as high as ono cent,) more than those of other makers.,Each package, is indorsed Potters, Varnish-makers, or Glass-makei.s, accordtng to its quality. And these evidencie of„quality aro- not placed upon the packages,'nor aro the .goods sent into 0 market under this " impriaiiitifr"”of Harrison . Brother s .& Co.,leintil the following pre cautions have boon taken. They buy only the best brands of Lead. Not satisfied with the trade reputation of these brands, they are carefully analyzed. If they pass ,-11. satisfactory examinativthey are then oxidized. To prevent even a possibility of error, a &Utica]. test is then made 7411 - OilAtind Gums' for Varnish, &c.; also on Earthenware or Bisch , it, and with Glass in a retort. Ilavi,ng passed these tests, theyltro--eonSidered applicable for the uses specified and aro so indorsed.. The trades:spoken of; therefore, may fuel in using the Red Load and Litharge, prepared by this firm, that they do so absolutely-without risk, and With acertainty that their pro-' duct, whether Flint Glass, Earthenware, Rubber or Varnish,.will have proper justice done it. -It is a too prevalent custom with White Lead tnanufacturers, whoso metal ,has escaped complete corrosion in the beds, to.work up the Blue Load which remains into Red Load and Litharge. ,These--refuse -scraps-may-not-ho- fit- for 'such-purposes, and con sumers using products - thus made expose themsolveii to' serious risks. They-are cheap-at , no price for consumption , unless accom panied by a written guaranty against damage.

Much skill and experience are necessary in the preparation of these important Pyrolignates of Lead, and the products of this department of the works of Harrison Brothers & Co. always command a preference by reason of their superior excellence. This firm was the first, and for many years-the only manufacturer of Pyrolignates of Lead in .thaUnited States.

Wood Al cohol (Methyl Spirits) is much used.in lieu of grain Alcohol (Fithyl Spirits) by Varnish Manufacturers as a solvent for Shellac, also by Dyers for Aniline Colors, for• which latter purpose it seems to be specially adapted, owing, as has been suggested, td acertain simi larity of origin. In fact twenty parts are found to becqUal as a solvent to thirty parts of alcohol, butte must be very, pure and perfectly white. The article produced here is specially adapted to this end. PAINT GRINDING DEPARTMENT In the second story of this . sectfon of the - Worms - are placed the mixers, in which by machinery the White Lead is kneaded with a suitable quantity of pure Linseed Oil. When thoroughly mixed the pasty mass descends to the first story, where, after being finely ground through two mills, ono of which empties into the. other's hopper, it - is'discharged.into tubs and is ready for packing. There are two tiers - of those mills, (those iu the upper being fed from the story above, and grinding into the lower,) having an aggregate capacity of seven to ten tons per day. Here are stacks of cans of all sizes,-of—me;tallie pails, kral of wooden -kegs,- for _receiving, the White Load. The wooden kegs are carefully protected by an interior coating of Shellac Varnish,.which in a great Measure pre,- vents absorption of oil. The patent iron: ehns, hoWever, which are used by this firm appear to be, as regards the quality of work manship, strength and durability of material', eXcoedingly'de, , iirable, and the oil not being, absorbed, as in the wooden kegs, paints of all kinds can be kept for years -unimpaired; so strong are they, too, that shipments unprotected by packing may be f3afel3 made to any distance. We were much interested in observing the unerring celerity with which, by an, exceedingly ingenious but simple ma chine, these metallic pails, when tilled, were in the twinkling of an eye topped and securely sealed with strong tin lids. , OR PAINT AND VARN,TKI ItEMOVER This article was invented and patented by Howard C. Kearny, and the patent and eXclusive right to manufacture were purchased by Harrison Brothers & Co. It is prePared in-a building adjoining the Brown Sugar of Lead Works, which is properly equipped with apparatus for making the -necessary mixtures. This substance is in the form of a paste., It is easily applied and will remove the harvest- and oldest paint from any surlhce in abc4d, thirty, uninutes, without scraping, and without injuring the wood or making it unfit ( to receive fresh paint. It will remove varnish from elaborately carved furniture and prepare it for Mi.( The cost of removing paint from old shutters,-&c., by burning, is about twenty-five cents per foot, and the'wood is apt to be damaged by charring; by this Resolvent, the work can be done, in much' less time and without the slightest possihility,of damage to the wood, fbr three to -four cents per foot.
