THE DIVISION OF TIME. j Many ages must luu'e elapsed after the, creation of the world before any meshed of, computing Time, or of dai'ng events, was; brought into cstnblislied use. Atu very ■ early period, time was measured by the rovpjutions of the moon, the seasons sue-| 'i'jCesaiyo returns of labor and rest; but so tMe os the age of.Honier tv formal calender seems to Imvo been unknown to history, or a register of events. The division of days into weeks is the most ancient way of waking time, probably took pinqc at the Creation. The next di yiaipp wns lint of montin, which uppen ml fo hnvc been in iisc-befnn; the: r’luoil. — 1 *Tho months were rnarked bv the ri-vuki tions of the moon, consequently were cal-* led lunar months. The highest natural division of time is into years. At first a year consisted ol only twelve lunar months. It is supposed that this method of reckoning was in use ns early as the Lelugo, and tlmt it con tinued lor many ages after, lint this was n very imperfect mode of computing time, for a luner your was nearly eleven days shorter then a solar year; hence the months conid not very long correspond with the season, liven in the space of 17 years tjie winter months would have changed places with those of summer. The calender which is now generally ‘ndoplcd in the Christian world was institut ed by Romulus. [lis y ear began on the 1 st of March and continued only ten months, or about 30-1 days, hence was ypry imperfect. Numn gave tho year 33$ days, added two months, and transfer red tho beginning of the year to the 1 st pf January. But this was still making the yenr too short. When Julius Cresnr obtained the sover eignty of Rome, he found the months had changed from the seasons, and in order to bring them forward to their places, he fowled P long year of If) months or -CIO ijliiys, -..This has been called the year ol ieponfusion. It ended January 1 st, forry five years beforo Christ. From this period Jho Julian year of 305 day 9 and 0 hours commenced, The common years contain ed Stif) days, bu' once every fuiir years ,lhe six hours amounted to nnother duy, -pnd this was added to the twenty-eighth ol February, or the sixth calends of March, yvhirjh yvus to be reckoned twice, hence Jhis year was stvled Bisscxile, or Leap year. The Julian yenr, however, wus still im perfect, for the earth performs its, nnnuul circuit round the sun in three hundred and sixty-five days, five honrs and forty-eight minutes, forty-five and a hnlf seconds; ‘"hence the solar venr was shorter tlinn Ju- lian, or civil year, hv elevon minutes, and fourteen nnd a half seconds, which in two hundred and thirty years amounted to a day. In the course of time this inconvenience becoming 100 considerable to bo unnoticed, Pope Gregory, XIII, substituted a new cal ender, called the Gregorian Calender or new style. It was published in March, A. D. 1582. Ten days hud now been gained by ihe old mode of reckoning, and theso were struck out of,the month of Oc- Jobcr following, by reckoning the fifth day of that month the fifteenth. And in order to prevent the occurrence pf n similar variation in time to come, he ordained that one dny should be added to every fourth year as before, and that front the year 1680 every fourth centenial year should bo reckoned ns a leap year, and the Other three centenial years ns common ones. Thus the years 1700, 1800, IBOu, 8100, 2500, etc., are to be reckoned ns common oneS, and 1600,2000, 2400, etc., as leap years. Even this correction is not absolutely exact, yet tlje error is so small ns !o hardly vary one day in over a thou sand years. The mndo of computing time as estab- lished bv Gregory is called New Style, and that by Julius, Crnsar, Old Style. The new style wns adopted by Spain, Portugal and part of Italy on the snmo day ns Rome, and in France on the tenth of December following which was reckoned the twenti eth dnv. But in Grunt Britain this change wus not adopted until September, 1752, when 170 years had elepsed since tho Gregori an alterations, consequently a little more than another day had been gained. It was therefore enacted by Parliament thut elev. en clays instead of
