His father, James, held several offices in the state during and after the Revolution, and was a dele- gate to congress in 1777-8. The son studied at Williams college, and afterward attended medical lectures at Philadelphia. After four years' prac- tice at Cambridge, Md., he returned to Dover, where he became renowned as a surgeon. Prom 1814 till 1820 he resided in New York. He was often a member of the state senate, over which he presided for nearly fifteen years, and he was acting governor of Delaware in 1801-'2.


SYLVESTER, Herbert Milton, author b. in Lowell, Mass., 20 Feb., 1849. He was fitted to en- ter college at Bridgeton academy, Bridgeton, Me., but entered the law-office of William Pitt Fessen- den in Portland, and was admitted to the bar in April, 1872, and settled in Boston, Mass. He has the reputation of being a good landscape artist. He has published " Prose Pastorals " (Boston, 1887) And " Homestead Highways " (1888), and is now (1888) engaged upon a novel descriptive of New England country life.

SYLVESTER, James Joseph, English author, b. in London, England, 3 Sept., 1814. He was graduated at Cambridge, became a professor of natural philosophy at University college, London, and was made a member of the Royal society in 1839. He came to this country and held the chair of mathematics in the University of Virginia in 1841-'2, and was appointed to a similar profes- sorship at the Royal military academy, Woolwich, in 1855. He was professor of mathematics at Johns Hopkins university, Baltimore, in 1876-'83, and in December, 1883, was elected Savilian pro- fessor of geometry at Oxford. He is a member of many learned societies both in Europe and this country, received the medal of the Royal socie- ty in 1860, and the Copley medal in 1880, and has been the recipient of honorary degrees from various colleges. He was the founder and the first editor of the " American Journal of Mathe- matics," is the author of a large number of im- portant scientific memoirs, 112 of which, published previous to 1863, are in the Royal society's index of scientific papers. He has given a theory of versification in a volume entitled " Laws of Verse " (London, 1870) ; has invented the plagrograph, an instrument which, in addition to altering the mag- nitude of an object, possesses the property of rotat- ing its image through any desired angle ; the geo- metrical fan, which has been applied to the con- struction of a cheap astronomical spectroscope; and other geometrico-mechanical instruments. He has developed a method of transferring circular into rectilinear or parallel motion, based upon the discovery of a French engineer, thereby adding immensely to the resources of the mechanician. In December, 1885, Prof. Sylvester made known his theory of reciprocants, which, it is claimed, more than doubles the resources of algebra.


SYLVESTER, Nathaniel Bartlett, author, b. in Denmark, Lewis co., N. Y., 22 Feb., 1825. Both his grandfathers were soldiers of the Revolution. He received his early education at the Denmark academy, studied law at Lowville, N. Y., and was admitted to the bar at Oswego, N. Y., 5 April, 1852.

SYLVIE, Edouard (sil-vee), French naturalist, b. in Riom, Auvergne, in 1670; d. in Lyons in 1739. He studied in the College Louis le Grand at Paris, entered the church, and was appointed by the king to a rich abbey in Lyons. Devoting his leisure time to the study of mathematics and natu- ral history, he presented several valuable memoirs to the Academy of sciences, which induced that body to propose him to the king for a mission to South America. Louis XIV. placed a man-of-war at Sylvie's disposal in order to facilitate his work, and from 1701 till 1703 he visited Santo Domingo and several ports of the Caribbean sea, prepared a chart of the Gulf of Mexico, and made valuable observations. In the following year he visited Guiana, Brazil, Montevideo, and Buenos Ayres, landed on Staten island, and made the ascent of its snowy range of mountains. Doubling Cape Horn, he coasted Chili and Peru to Callao, and, penetrat- ing into the interior, explored the Andes. Sylvie afterward returned to the West Indies, and so- journed several months in Santo Domingo, occu- pied in drawing a map of the French part of the island. His vessel arrived at La Roche! le, 15 Oct., 1710, and Sylvie's valuable collections were pre- sented to the Academy of sciences, which elected him a corresponding member. His works include "Explications de l'herbier et des collections rap- portees d'Amerique par l'Abbe Edouard Sylvie " (3 vols., Paris, 1711-13) ; " Relation d'un voyage de la mer du Sud aux cotes de la Guiane, du Bresil, de la Terre des Etats, du Chili et du Perou, avec une description de la cote septentrionale du detroit de Le Maire " (3 vols., 1714-'16) ; " Voyage a travers le Golfe du Mexique, suivi d'une description des lies Antilles de l'Amerique, et en particulier de l'ile de Saint Domingue (2 vols., 1720-'l); and " Journal des observations d'un voyage au Perou et au Chili " (5 vols., 1726-'8).

Chadbourne, of Williams college, on a visit to Iceland, and gave the results of his journey in " Pen and Pencil Sketches of Faroe and Iceland " (London, 1861).
