MaeARTHUR, Arthur, jurist, born in Glasgow, Scotland, 26 January, 1815. He came to this country when a child with his parents, spent a year in Wesleyan university, Connecticut, studied law in New York, and was admitted to the bar in 1841. He began practice in Springfield, Massachusetts, and in 1843 was appointed public administrator for the county of Hampden, and judge-advocate for the western division of the militia. In 1849 he removed to Milwaukee, Wisconsin, and in 1851 was elected city attorney of that city, in which office he served one term. In 1855 he was elected lieutenant-governor of the state and served a part of his time as governor during a vacancy that was created by the resignation of Governor Barstow. In 1857 he was elected judge of the 2d judicial circuit, and he was reelected in 1863. He was appointed a United States commissioner to the Paris exposition of 1867. In 1870 he was appointed associate justice of the supreme court of the District of Columbia, which place he resigned on 1 April, 1887, under the act of congress permitting Federal judges to retire on full pay after reaching the age of seventy. He has been for many years president of the Washington humane society, and occupies a similar post in the associated charities for the district. He is also president of the board of regents of the National university at Washington. Judge MacArthur has published four volumes of reports containing the more important decisions of his court (Washington, 1875 et seq.), and is the author of " Education in its Relation to Manual Industry" (New York, 1884). He has now (1888) nearly ready for publication a work called the " Biography of the English Language." He has for many years delivered lectures on historical and literary subjects which will probably be gathered into a volume soon.
