Dio Lewis, an American physician, born at Auburn, N. Y., March 3, 1823. He was educated at Harvard medical school in Boston, and practised medicine at Port Byron and at Buffalo, N. Y. He published a monthly medical magazine at Buffalo, in which he constantly deprecated the use of dr,ugs, and advocated the introduction of physical exercise as a part of public education. In 1863 he settled in Boston, and founded an institution for training teachers in his new system of physical education, which since 1855 he had been engaged in advocating and introducing throughout the country; and in 1864 he established in Lexington, Mass., a school for young women, in which all rules of government were abandoned. In September, 1868, the buildings were burned, and a year later the school was given up. Since then he has lectured frequently, principally on hygienic topics, and is now (1874) engaged in the temperance reform. He has published "New Gymnastics" (Boston, 1862); "Weak Lungs, and how to make them Strong' (Boston, 1863); "Talks about People's Stomachs" (1870); "Our Girls" (New York, 1871); and " Chats with Young Wo-men" (New York, 1874).
