a lake recently discovered in the interior of Eastern Africa. In October 1856, the Royal Geographical Society, having determined to send out an expedition to the reputed Lake Nyassa in Eastern Africa, to explore the surrounding country, and if possible to penetrate northwards to the source of the Nile, appointed Captain Burton to command the expedition. He accordingly, after being joined by Captain Speke and others, arrived at Zanzibar in December 1856, but was prevented from leaving that island till June 1857, when the rainy season was over. On the 26th of June they landed on the mainland, and began their journey westwards into the interior; and on the 13th of February 1858, they gained sight of Lake Tanganyika. The lake lies between S. Lat. 3° 10. and 7° 46.; E. Lon. 29° 35. and 30° 35. It is of a long narrow form, its length being upwards of 300 miles, while its breadth at the southern extremity, where it is widest, is about 65 miles; and it gradually diminishes in width towards the other end, near which it is no more than 10 miles across. Its water is fresh and deep, and its elevation above the sea is 1844 feet. There are several islands on its surface. The chief river that falls into it is the Malagarazi, from the east. The first view of this lake from the adjacent hills is described by Captain Burton as exceedingly picturesque. Beyond the steep and rugged slope of the hill lies a flat green sward, bounded by a narrow strip of sand, on which the waves of the lake break. The light blue waters, studded with islands, stretch to the south and north; on the other side rises a ridge of purple hills, while the villages and cultivated land on the shores, and the fishermen's boats on the lake, add animation to the scene.
