[English naphthyl, and amine.] Na-piër', subst . [John Napier, of Merc hist on, in Scotland, a celebrated mathematician, known also as the inventor of logarithms.] (See the compounds.) Napier's bones, Napier's rods, s . pl . Math.: A set of rods contrived by Baron Napier, and first described by him in 1617, for the purpose of facilitating the numerical operations of multiplication and division. They consist of pieces of bone, or ivory, in the shape of a parallelopiped on, about three inches long and three-tenths of an inch in width, the faces of each being divided into IMG:content-1561.png:[ocr errors][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][ocr errors][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small][merged small] manner that the numbers at the top shall exhibit the multiplicand, and on the left of these rods place the rod of units. In the rod of units seek the right hand figure of the multiplier, which, in this case, is 7, and the numbers corresponding to it on the other rods. Be- 53802 ginning on the left add the digits in each parallelogram, formed by triangles of ad- jacent rods, and write them down as in ordinary multiplication; then take the sum of the several products as in ordinary multiplication, and it will be the product required. From the outer most triangle on the line with 7, write out the num ber there found, 6; in the next parallelogram on Crime an war, and afterward adopted by various European nations, and by the United States.
