TROY WEIGHT.

Note.-Most children have very erroneous or indistinct ideas of the weights and measures in common use. It is, therefore, strongly recommended for teachers to illustrate them practically, by referring to some visible object of equal magnitude, or by exhibiting the ounce ; the pound; the linear inch, foot, yard, and rod; also a square and cubic inch, foot, and yard; the pint, quart, gallon, peck, bushel, &c.

148. Troy Weight is used in weighing gold, silver, jewels, liquors, &c., and is generally adopted in philosophical experiments.

OBS. 1. Troy Weight was formerly used in weighing articles of every kind. It was introduced into Europe about the time of the Crusades from Cairo in Egypt, and was first adopted by the city Troyes, in France, from which some suppose its name was derived. Others think it was derived from Troy-novant, the former name of London.*

2. The standard of Weights and Measures is different in different States of the Union. In 1834, the government of the United States adopted a uniform standard for the use of the several custom houses and other purposes.

3. The standard unit of Weight adopted by the Government is the Troy Pound of the United States Mint, which is identical with the Imperial Troy pound of England, established by Act of Parliament, A. D. 1826.t

QUEST.-148. What is Troy Weight? Repeat the Table. Obs. When was Troy Weight introduced into Europe? From what was its name derived? Do all of the States have the same standard of weights and measures? What is the standard unit of weight adopted by the government of the United States?

3. Gross weight is the weight of goods with the boxes, casks, or bags which contain them.

Net weight is the weight of the goods only.

4. Formerly it was the custom to allow 112 pounds for a hundred weight, and 28 pounds for a quarter; but this practice has become nearly or quite obsolete. In buying and selling all articles of commerce estimated by weight, the laws of most of the States as well as general usage, call 100 pounds a hundred weight, and 25 pounds a quarter.
