Livingstone's Researches

It would be impossible to overestimate ] the importance of Dr. Livingstone's researches and diacoveries. By his own exertions, beset with perils and obstacles which would have driven back a man leas j courageous and determined, he haa filled up a great spaoe in the map of África; he was the first European whose eyes beheld the vast inland seas whose existence had been vaguely conjectured from tive reports; ho laid down the course j of lmndreds of new rivers, and noted ! their volume and the velocity of their flow.
