carapegua, an interior town of paraguay, 37 m. s.e. of asuncion on the old route between that city and the missions. pop. (est.) 13,000 (probably the population of the large rural district about the town is included in this estimate). the town (founded in 1725) is situated in a fertile country producing cotton, tobacco, indian corn, sugar-cane and mandioca. it has two schools, a church and modern public buildings. carat (arab. _q[-i]r[-a]t_, weight of four grains; gr. _[greek: ker['a]tion]_, little horn, the fruit of the carob or locust tree), a small weight (originally in the form of a seed) used for diamonds and precious stones, and a measure for determining the fineness of gold. the exact weight of the carat, in practice, now varies slightly in different places. in 1877 a syndicate of london, paris and amsterdam jewellers fixed the weight at 205 milligrammes (3.163 troy grains). the south african carat, according to gardner williams (general manager of the de beers mines), is equal to 3.174 grains (_the diamond mines of south africa_, 1902). the fineness of gold is measured by a ratio with 24 carats as a standard; thus 2 parts of alloy make it 22-carat gold, and so on.
