SALES LATERRIERE, Peter de, born in Canada in 1789; died there, 15 December, 1884. He studied medicine in London under Sir Astley Cooper, and on his return to Quebec soon became distinguished as a surgeon. He took part in the war of 1812 as surgeon-in-chief of the Canadian voltigeurs. In 1814 he visited France and England, where he married the daughter of Sir Fenwick Bulmer, in the following year returned to Canada, and resided in Quebec up to 1823. Here he took a prominent p.art in Canadian politics, giving expression to his wews in the public journals, and denouncing the oligarchical rgyime that then prevailed. In 1823 he went to England, where he published "A Political and Historical Account of Lower Canada, with Remarks on the Present Situation of the People " (London, 1830), which created a sensation in Canada, and delayed the union of the provinces. --His brother, Mark Pascal, born in Baie-du-Febvre in 1792, studied medicine at the University of Pennsylvania, where he was a pupil of Dr. Benjamin Rush. He obtained his degree in 1812, and established himself in Quebec. During the war of 1812 he served as surgeon-general of the militia of Lower Canada, and in 1814 retired from his profession and took up his residence in his seigneurie of Eboulements. He was elected a member of the provincial legislature in 1824, and has continued to take a leading part in Canadian polities. The immense and difficult highway through the Lau-rentides, which has brought that coast into communication with Quebec, is due to his enterprise.
