In 1866 the indefatigable Dr Livingstone is again in Africa, with the determination of filling up the great gaps in our knowledge of the lake region from Nyassa to Tanganyika, beginning the great journey from which he has not yet returned.

News arrived in England, in September 1866, that the traveller had, for a third time, entered the Rovuma river, and had succeeded in penetrating for 130 miles from its mouth, where he had found a friendly chief, whose residence he intended to make the starting-point of his expedition to the northern end of Nyassa, and the south of Tanganyika.
