We again turn to the testimony of Dr. Livingstone; and at this time, when there is so much uncertainty as to the safety of our great traveller, the mind naturally recurs to the state of suspense almost hopeless, save for the firm opinion expressed by Sir R. Murchison, which followed on the report of his death given by the Johanna men at Zanzibar. Great was the rejoicing at the tidings of his safety, and hearty were the congratulations offered to their president by the members of the Geographical Society at the meeting at which Dr. Livingstone's letter announcing his safety was read. While all who spoke claimed him as the great geographer, the African explorer, the undaunted traveller, there was one present who, having himself, with Livingstone, witnessed some of the horrors of the East African Slave-trade, endeavoured to impress upon the fashionable and learned assembly, that Livingstone had other objects in view beside the mere solution of geographical problems—that he was a true philanthropist, and that one of the causes nearest to his heart was the suffering oppressed slave.
