hypothesis, it gives additional weight, provided the river swell in early September"--which it did. In his "Journal" (p. 224), we find a memorandum, written as it were with a dying hand, "Hypothesis confirmed. The water..." On February 24, 1854, Dr. Livingstone, after leaving what he calls the "Dilolo Lake," found on an almost level plain, some 4,000 to 5,000 feet high and then flooded after rains, a great water parting between the eastern and the western continental shores. I have carefully considered the strictures upon this subject by the author of "Dr. Livingstone's Errors" (p. 101), and have come to the conclusion that the explorer was too experienced to make the mistakes attributed to him by the cabinet geographer. The translation "despair" for "bitterness" (of the fish?) and the reference to Noah's Deluge may be little touches ad captandum; but the Kibundo or Angolan tongue certainly has a dental though it lacks a cerebral d. The easterly flow was here represented by the Leeba or upper course of the "Leeambye," the "Diambege of Ladislaus Magyar, that great northern and north-western course of the Zambeze across which older geographers had thrown a dam of lofty mountains, where the Mosi-wa-tunya cataract was afterwards discovered. The opposite versant flowing to the north was the Kasai or Kasye (Livingstone), the Casais of the Pombeiros, the Casati of Douville, the Casasi and Casézi of M. Cooley (who derives it from Casezi, a priest, the corrupted Arabic Kissis ); the Kassabi (Casabi) of Beke, the Cassaby of Monteiro and Gamitto (p. 494), and the Kassaby or Cassay of Valdez. Its head water is afterwards called by the explorer Lomame and Loke, possibly for Lu-oke, because it drains the highlands of Mossamba and the district of Ji-oke, also called Ki-oke, Kiboke, and by the Portuguese "Quiboque." The stream is described as being one hundred yards broad, running through a deep green glen like the Clyde. The people attested its length by asserting, in true African style, "If you sail along it for months, you will turn without seeing the end of it:" European geographers apparently will not understand that this declaration shows only the ignorance of the natives concerning everything a few miles beyond their homes. The explorer (February 27,1854) places the ford in south latitude 11° 15' 47", and his map shows east longitude (G.), 21° 40' 30", about 7° 30' (=450 direct geographical miles) from Novo Redondo on the Western Coast. He dots its rise in the "Balobale country," south latitude 12° to 13°, and east longitude 19° to 20°. Pursuing his course, Dr. Livingstone (March 30) first sighted the Quango (Coango) as it emerged from the dark jungles of Londa, a giant Clyde, some 350 yards broad, flowing down an enormous valley of denudation. He reached it on April, 1854, in south latitude 9° 53', and east longitude (G.) 18° 37', about 300 geographical linear miles from the Atlantic. Three days to the
