ANTHONY, William Arnold, physicist, born in Coventry, Rhode Island, 17 November 1835. He was educated at the Yale (now Sheffield) scientific school, and received his degree in 1860. From 1857 to 1860 he was principal of a graded school in Crompton, Rhode Island During 1860-'61 he taught the sciences in the Providence Conference Seminary, East Greenwich, Rhode Island, after which, from 1861 to 1863, he followed his profession in various capacities and in different localities. Again, from 1863 to 1867, he taught the sciences in Franklin, New York, and in 1867 he became professor of physics and chemistry in Antioch College, where he remained until 1870, when he was called to occupy a similar chair in Iowa Agricultural College. During 1872 he accepted the professorship of physics in the then recently established Cornell University, which he still occupies. Although his work has been principally that of teaching, he has found time to gratify his fondness for mechanics. He designed and constructed, during the year's 1857-'61, two turbines, one of which gave an efficiency of 87 per cent., whose floats were carefully formed to curves deduced from a mathematical investigation of the flow of fluids. In 1875 he constructed a Gramme dynamo-electric machine for 25 amperes and 250 volts. This was built at a time when only the most general descriptions of such machines were at hand. He has also made a large tangent galvanometer, which measures accurately currents from 1/10 to 250 amperes. Professor Anthony is a member of the American Association for the Advancement of Science, and of the American Institute of Electrical Engineers. His published papers include contributions read before these societies, and other numerous scientific articles which have appeared in the "American Journal of Science," "Journal of the Franklin Institute," the "Popular Science Monthly," and several electrical journals. He is joint author with Professor C. F. Brackett of an "Elementary Text-book on Physics" (New York, 1885). ANTONELLI, Juan, engineer, born in Gaeta, Italy, about the middle of the 16th century" died in Spain in 1616. He went to Cuba in 1584, where he made the plan and superintended the construction of the Morro Castle and Punta Fortress in Havana, in 1589. Before they were finished he went to Vera Cruz, Mexico, and planned the famous fortress of San Juan de Ulna. He returned to Cuba, and afterward went to Spain, where he died.
