6. MEASURE OF TIME. 1 Pennyweight 24 gr. DIVISION II-TROY WEight. 24 Grains These are the denominations of Troy Weight when used for weighing gold, silver, and precious stones (except diamonds). But Troy Weight is also used by Apothecaries in compounding medicines, and by them the ounce is divided into 8 drams, and the dram into 3 scruples, so that the scruple is equal to 20 grains. For scientific purposes the grain only is used; and sets of weights are constructed in decimal progression, from 10,000 grains downwards to of a grain. The carat, used for weighing diamonds, is 3 grains. The term, however, when used to express the fineness of gold, has a relative meaning only. Every mass of alloyed gold is supposed to be divided into 24 equal parts; thus the standard for coin is 22 carats fine, that is, it consists of 22 parts of pure gold, and 2 parts of alloy. 1 Hour 1 Day 1 Week 1 Lunar Month 1 Calendar Month 1 Year 1 Common Year 1 Leap Year In 400 Years, 97 are leap years, and 303 MEMORANDA FOR NEXT YEAR, 1859.
