COIT, Henry Augustus, educator, born 20 January, 1831. He was educated at St. Paul's school in College Point, Long Island, and at the University of Pennsylvania, but was not graduated. He entered the ministry of the Protestant Episcopal church, and on the foundation of St. Paul's school, in Concord, New Hampshire, by Dr. George Shattuck, was chosen its first rector. The school, opened in 1856 with five or six boys, has since grown to be one of the largest in the country, numbering about 300 pupils and twenty masters, and occupying twenty buildings. Its rector was made a doctor of divinity by Trinity College in 1863, and the success of the school is largely due to his efforts. In 1868 he visited England, and studied the workings of the large public schools there, many features of which he has introduced into St. Paul's. Dr. Coit has been a trustee of Trinity College for four years, a delegate to the general convention of his church for many years, and is a preacher of much power. He has published numerous sermons and addresses, and has contributed to periodical literature.--His brother, Joseph Howland, was professor of mathematics and natural science in St. James's College, Maryland, until the closing of that institution in 1865, when he became associated with his brother in St. Paul's school, Concord, of which he is now vice-principal. He has edited a "Life of Bishop Ker-foot."--Another brother, James Milnor, chemist, born in Harrisburg, Pennsylvania, 31 January,-1845, was educated at St. Paul's school, Concord, New Hampshire, and at Hobart College, Geneva, New York, where he was graduated in 1865. In 1881 he received the degree of Ph.D. from Dartmouth. During 1873-'5 he was the general manager of the Cleveland tube-works, but has since given his attention to the teaching of chemistry and the natural sciences, principally at St. Paul's school. Dr. Colt has devised several improved forms of chemical apparatus, and has published "A Short Manual of Qualitative Analysis" (Concord, New Hampshire, 1883), and "A Chemical Arithmetic, with a Short System of Qualitative Analysis" (Boston, 1886).
