Mr. William Terrell, an American meteorologist of world-wide reputation, died in Kansas City, Mo., September 18th, about seventy-four years old. He was graduated from Bethany College in 1844, became assistant in the American Ephemeries and Nautical Almanac in 1857, and held the place for ten years; was then appointed on the staff of the United States Coast Survey, when he invented the machine for predicting the maxima and minima of tides; was made assistant, with the rank of professor, in the Signal-Service Bureau in 1882; and retired from that position in 1886 to make his home in Kansas City. He published many works, large and small, of researches on the tides or pertaining to meteorological problems; a volume on Recent Advances in Meteorology (1888); a Popular Treatise on the Winds in 1889; and contributions to scientific journals and societies on such topics as thermal radiation, cyclones, tornadoes, and related subjects of terrestrial physics. His earliest scientific writings were contributed in 1856 to the Nashville Journal of Medicine and Surgery. He was a member of the National Academy of Sciences, and an honorary member of the meteorological societies of England, Germany, and Austria.
Prof. Martin Duncan, F. R. S., whose death has been recently announced, was a special student of fossil corals and echinoderms, and published some valuable memoirs upon them.
