GEORGE FRANCIS, was born at Chichester, in Sussex, in 1795. He was scarcely thirteen when he entered the navy, and in 1816 he joined Lord Exmouth's squadron for the bombardment of Algiers. At Malta, Lyon was prevailed upon by the traveller Ritchie to accompany him on an expedition to North Africa. Lyon reached the port of Tripoli on the 25th November 1818, and spent the greater part of the two following years in making explorations in Soudan, the course of the Niger, &c. Ritchie died, and Lyon was compelled to return to England on the 29th July 1820, when he published an account of his expedition. Next year Lyon got the command of the Hecla, and in concert with Captain Parry of the Fury, set out on a voyage of discovery to Hudson's Bay. They returned in 1823; and an account of this expedition was published at London in 1824. Lyon made an unsuccessful voyage next with the Griper to Repulse Bay, of which he gave an account in 1825. The rest of his life was spent chiefly in a survey of the mines of Mexico. He died in 1832.
