Wilhelmshaven, a seaport town of Germany, in the former territory and at the N. W. end of the bay of Jade, since 1873 part of the Prussian province of Hanover, 40. m. N. W. of Bremen; pop. about 10,000. It grew up around the naval dockyard and military post inaugurated in 1869, and since used as the main station of the German navy. The port was laid out on swampy land purchased in 1853 from Oldenburg, and is diked against the sea. It has an inner and an outer basin, the latter flanked by piers 4,000 and 10,000 ft. long, and there are three dry docks for building and repairing ironclads, and factories for steam engines. The total cost of all the works when completed will probably reach $40,000,000.

Willebrord Snell

Willebrord Snell, a Dutch mathematician, born in Leyden in 1591, died there, Oct. 31, 162G. He studied law, but devoted himself principally to mathematics. When 17 years old he published an essay in which he endeavored to restore a lost treatise of Apollonius. He travelled in Germany, and won the friendship and esteem of Kepler. In 1613 he succeeded his father as professor in the university of Leyden. He was the first to make a trigonometrical measurement of an arc of a meridian, and thence to calculate the size of the earth. His result was erroneous, on account of the imperfection of the instruments then in use; but he himself discovered the errors. He also discovered the law of the refraction of light (see Light, vol. x., p. 438), and improved the methods of approximating to the ratio of the radius to the circumference of the circle. His most important work is Eratosthenes Batavus, sive de Terroe Ambitus vera Quantitate (Leyden, 1617).
