SMALLWOOD, Charles, Canadian meteorologist, born in Birmingham, England, in 1812; died in Montreal, 22 December, 1873. He became a physician, and, emigrating to Canada in 1853, settled at St. Martin's, Isle Jesus, Canada East, and acquired a large practice. He soon afterward established his meteorological and electrical observatory, a description of which was given in the "Smithsonian Reports." He discovered the effects of atmospheric electricity on the formation of snow crystals, and investigated the action of ozone in connection with light, and that of electricity in the germination of seeds. In 1858 Dr. Smallwood received the honorary degree of LL.D. from McGill college, and was appointed professor of meteorology in that institution, to which was subsequently added the chair of astronomy. In 1860 the Canadian government made him a grant for the purchase of magnetic instruments, and in August, 1861, he began making observations. When the United States signal-service system was established, Dr. Smallwood arranged for stations in connection with it in Montreal and other Canadian cities. He was one of the governors of the College of physicians and surgeons, of Lower Canada, and was a member of many scientific and literary societies in America and Europe. He was the author of numerous articles in scientific periodicals and the "Smithsonian Reports," and of contributions to Canadian meteorology furnished to various magazines for more than twenty years.
