“ Hitherto, and until 1847, M‘Clintock’s service was almost wholly on the American coasts, but in 1848 he joined the Arctic expedition under Sir James Ross in search of Sir John Franklin’s ships, as second lieutenant of the “Enterprise.” In the second search expedition (1850) he was first lieutenant of the “Assistance,” and in the third (1854) he commanded the “Intrepid.” On all these expeditions M‘Clintock carried out brilliant sleigh journeys, and gained recognition as one of the highest authorities on Arctic travel. ”
