Notes on the Congo River . 
The article proves hypsometrically that the 
Lualaba, in which the explorer found the head 
waters of the Egyptian river, cannot feed the Tan¬ 
ganyika nor the Lake Nzige (N’zlghe, Mwutan, 
Chowambe, or Albert Nyanza Lake), nor even the 
Bahr el Ghazal, as was once suspected. From the 
latter, indeed, it is barred by the water parting of 
the Welle, the “ Babura” of Jules Poncet (i860), in 
the land of the Monbuttu ; whose system the later 
explorer, Dr. Schweinfurth, is disposed to connect 
with the Shari. Hydrometrically considered, the 
Lualaba, which at Nyangwe, the most northerly 
point explored by Dr. Livingstone (1870), rolls a 
flood of 124,000 cubic feet per second in the dry 
season, cannot be connected either with the Welle 
(5,100 cubic feet), nor with the Bahr el Ghazal 
(3,042 to 6,500 cubic feet), nor with the Nile 
below the mouth of the Bahr el Ghazal (11,330) ; 
nor with the Shari (67,500) ; nor with the shallow 
Ogobe, through its main forks the Rembo Okanda 
and the Rembo Nguye. 
But the Lualaba may issue through the Congo. 
The former is made one of the four streams ferried 
over by those travelling from the Cazembe to the 
translated by Mr. Keith Johnston from the “ Geogr. Mittheil- 
ungen,” i. 18, Bund, 1872, and published in the “Proceedings 
of the Royal Geographical Society,” No. 1, vol. xviii. of Feb. 24, 
1S73.
