TYLER, Samuel, author, born in Prince George county, Maryland, 22 October, 1809 ; died in Georgetown, D. C., 15 December, 1878. His father, Grafton, was a tobacco-planter. The son was educated at Dr. James Carnahan's school in Georgetown, devoting himself especially to Greek. He studied at Middlebury in 1827, and, after reading law, was admitted to the bar in 1831, and began to practise in Frederick, Maryland In 1852 he was elected one of three commissioners to simplify the pleadings and practice in all the courts of the state, and rendered important service in this capacity. His report, a profound discussion on the relative merits of the common and civil law. won wide approbation. In 1867 he was elected professor of law in Columbian college (now university), Washington, D. C., which office he held until his death. He received the degree of LL.D. from the College of South Carolina in 1858, and from Columbia in 1859. Early devoting himself to metaphysics, he contributed articles on this subject to various magazines, one of which, a "Discourse on the Baconian Philosophy," published in the" Princeton Review," was afterward issued in book-form (Baltimore, 1844). This " Discourse" gained hint the friendship and correspondence of Sir William Hamilton, the Scottish philosopher, who wrote to the author in 1848, advising him to abandon the practice of law and to devote himself exclusively to philosophy. On the death of her husband, Lady Hamilton presented Mr. Tyler with a portrait of Sir William as a token of her esteem. He also published "Robert Burns as a Poet and as a Man" (New York, 1848) . "The Progress of Philosophy in the Past and in the Future" (Philadelphia, 1858" 2d ed., 1868)" and a "Memoir of Roger Brooke Taney" (Baltimore, 1872).
