Eagle E. * The following account is abftracted from the "Act establishing a Mint, and regulating the Coins of the United States," paffed April 2nd, 1792. The money of account of the United States fhall be expreffed in dollars or units, difmes or tenths of a dollar, cents or hundredths of a dollar, and mills or thousandths of a dollar, The coins of gold, silver, and copper of the U. S. shall be of the following denominations, viz. Cop. per. Silver: Gold. 1. EAGLE, of the value of ten, dollars. 2. HALF EAGLE J. QUARTER EAGLE five dolls. wo and a half dolls. 6. QUARTER DOLLAR One fourth the dollar. The ftandard for all gold coins of the U. S fhall be eleven parts of pure gold and one part of alloy in twelve parts of the coin. The alloy is to be filver and copper, but the filver is not to exceed one half in the alloy. The Eagle fhall contain two hundred and forty feven and a half grains of pure gold, or two hundred and seventy grains of standard gold; and the other gold coins in the fame proportion. The fandard for all filver coins of the U. S. fhall be one thousand four huadred and eighty five parts of pure filver and one hundred and seventy nine parts alloy; and the alloy shall be pure copper. The Dollar fhall contain three hundred and feventy one and one fourth grains of pure filver, or of four hundred and fixteen grains of standard filver; and the other filver coins in the fame proportion. The Copper coins are to be pure copper. The Cent is to contain eleven penny weights of copper; and the Half Cent in proportion. The proportional value of gold to filver in all coins current by law in the U. S. fhall be fifteen to one, or fifteen pounds weight of pure filver shall be equal. to one pound weight of pure gold. All coins of gold and filver, iffued from the Mint of the U. S. fhall be a lawful tender in all payments at the preceding values when of full weight, and if cot of full weight, of proportional values. By this weight are weighed Gold, Silver, Jewels, Electuaries, and all liquors. An ounce of gold is divided into 24 parts, called carats, and an ounce of filver, into 20 parts, called pennyweights; therefore, to diftinguith fineness of metals, fuch gold as will abide the fire without lofs, is accounted 24 carats fine: If it lofe 2 carats in trial, it is called 22 carats fine, &c. A pound of filver which, lofes nothing in trial, is 12 ounces fine; but, if it lofe 3 pennyweights, it is 11 oz. 17 pwts. fine, &c. Alloy is fome bafe metal with which gold or filver is mixed to abate its fincnefs; 22 carats of gold, and 2 carats of copper, are esteemed the true standard for gold coin in England, the alloy being one eleventh part of the fine gold: and 11 oz 2 pwts. of fine filver, melted with 18 pwts. of copper, make the true ftandard for filver coin. NOTE. 175 Troy ounces, are precisely equal to 192 Avoirdupois ounces, and 175 Troy pounds are equal to 144 Avoirdupois. lb. Troy = 5760 grains, and 1 lb. Avoirdupois 7000 grains. ↑ By Avoirdupois are weighed all coarse and droffy goods, grocery and chandlery wares; bread, and all metals, except gold and filver. A barrel of pork weighs 200 lb.

Avoirdupois. 12 particular things make one dozen; 12 dozen 1 gross, and 144 dozen 1 great grofs. 20 particular things make a score, * All the weights now used by Apothecaries, above grains, are Avoirdupois. The Apothecaries' pound and ounce, and the pound and ounce Troy are the fame, only differently divided and subdivided. † All Scotch and Irish linens are bought by the English or American yard, which is the fame, and all Dutch linens by the Ell Flemish; but are all fold in America by the American yard; though the Dutch linens are fold in England by the Ell English, and the Scotch and Irish linens, as in America. The Scotch allow one English yard in every score yards. The ufe of Long Measure is to measure the distance of places, or any other thing, where length is confidered without regard to breadth. NOTE. 60 geometrical miles make a degree. 4 inches a hand. 5 feet a geometrical pace. 6 points make 1 line, 12 lines an inch, 12 inches a foot, and 6 feet one French toife, or Fathom, equal to 6 feet 4 inches, 8,812,875 lines, English measure. 1 English foot equal to 11 inches 3.1154 lines French. 66 fect, or 4 poles, make a Gunter's chain. 3 miles make a league. By the Calendar, the year is divided in the following manner : Thirty days hath September, April, June, and November; February twenty eight alone, and all the reft have thirty one. When you can divide the year of our Lord by 4, without any remainder, it is then Biffextile, or Leap Year, in which February has 29 days. 1296000 21600 360 = 12 = Zodiack. 10.

On this account, Julius Cefar ordained that one day fhould be added to February, every fourth year, by caufing the 24th day to be reckoned twice; and because this 24th day was the fixth, (fextilis) before the kalenda of March, there were in this year, two of thefe fextiles, which gave the name of Biffextile to this year, which being thus corrected, was from thence called the Julian year. A juft and equal measure of the year is called the periodical year, as being the time of the earth's period about the fun; in departing from any fixed point in the heavens, and returning to the fame again. The feveral points of the ecliptick having a retrograde, or backward motion, the equinox will, as it were, meet the fun; by which mean the fun will arrive at the Equinox, or first point of Aries, before his revolution is completed, and this space of time is called the tropical year. The Zodiack is a great circle of the fphere, containing the 12 figns, through which the fun paffea. |
