After a few years s])ent in general practice. Milchell turned his attentiim almost entirely to diseases of the nervous system, a field in wliidi he early achieved eminence. His special title to fame is derived from his elal)0- ration of the system of '"Ri'st Treatment" which has torne liis name for many years ami has been adopted, with modifications, the woild over. His earliest work of importance consisted of re- searches upon the chemical composition and pliysiological action of the venom of snakes, in ISOfi. and later. He was assistant surgeon to the I'. 8.

Dr. Jlitchell first turned his attention to fic- tion and general literature during the Civil War, when he wrote The Children's Hour, to be sold during the great fair of the Sanitary Commission in Pliiladelphia. Among other pieces of juvenile fiction was Tiic Wonderful Stories of Fuz-hus, the Fly. and Mother Grabcni, the Spider ( 1867). Of his short stories, the most notable was The Case of George Dedlow (1803). His first nov- els were He/ihzibali Guinness (1880).

Others followed, including: In War Time (1885): Roland lilake (1SS6); Far in the Forest (1889); Character- istics (1892) : 117ic;i .4// the Woods Are Green ( 1894) ; Hugh Wynne. Free Quaker (1897) ; The Adventures of Francois (1899) ; Dr. North and His Friends (1900) ; and Circumstances (1901). These stories deal with different historical and contemjiorary types of character, and are to be distinguished from the popular novels of their class by rather more insistence than is common on psychological and pathological analysis. Hugh Wynne is generally conceded to rank among the best stories of the American Revolu- tion yet written. MITCHELL, Sir Thomas Livingstone (1792- ls5.")i. An Kiiiilish explorer.
