TUTTLE, Charles Wesley, astronomer, born in Newfield, Maine, 1 November, 1829; died in Boston, Massachusetts, 17 July, 1881. He was educated in the schools of his native town and in Dover, where he learned the trade of a carpenter with his uncle, devoting his leisure to study. While still a lad he constructed telescope, which was a remarkable piece of mechanism considering that he had never seen such an instrument. He removed to Cambridge in 1849, in 1850 entered the observatory at Harvard as a student and was in 1851 appointed assistant observer. Owing to impaired eyesight, he was forced to resign his post, and then studied law at Harvard. He was admitted to the bar in 1856, and practised in Newburyport, and afterward in Boston until his death. In 1855 he was sent to England in charge, with his friend Sidney Coolidge, of a chronometric expedition of the United States coast survey for determining the difference of longitude between Liverpool and Cambridge. Harvard gave him the degree of A.M. in 1854, and Dartmouth that of Ph.D. in 1880. His leisure was devoted to historical and antiquarian research, and he won a high reputation as an original investigator. He was active in procuring the act of incorporation of the Prince society, of which he was treasurer and corresponding secretary, and was a member of various historical societies, before which he frequently read papers. He delivered the bi-centennial address before the New Hampshire historical society in 1880, in commemoration of the establishment of the first civil government over that province in 1680. He frequently delivered lectures upon astronomy, and contributed largely to astronomical journals. He was the author of a monograph on "Captain John Mason, the Founder of New Hampshire," edited, with historical illustrations, by John Ward Dean, and published by the Prince society (Boston, 1887). --His brother, Horace Parnell, astronomer, born in Newfield, York County, Maine, 24 March, 1839, was educated by his brother in Cambridge. He entered the United States navy, and became acting assistant paymaster, 17 February, 1863, assistant paymaster, 2 July, 1864, paymaster, 4 May, 1866, and was honorably dismissed on 3 March, 1875. In 1857 he invented a method of inserting a steel rifled core into brass or iron cannon, which method is extensively used by European governments, but a patent for which was refused by the United States patent-office. In 1861 he devised a method of signalling at long distances by using flashes made by a Drummond light, to correspond with the dots and dashes of the Morse telegraph system. He discovered thirteen comets between 1857 and 1866, and in 1861-'2 the asteroids Maia and Clytie. At present he is assistant computer in the United States naval observatory. Mr. Tuttle has computed "Pay Tables of the United States Navy " (Washington, 1872).
