5, from 'Lake Nyanza' to Lake Baringo, conclusively 

 proves that the latter is not 1 a sort- of backwater ' connected 

 with the former ' by a strait, at the same distance from the 

 East of Bipon Falls as the Katenga river is to the West/ 

 Nor is it a ' vast salt marsh' without effluent : the saline 

 water has evidently been confused with the lately reported 

 Lake Nairvasha or Balibali lying S. West of Doenyo Ebor. 

 Native description supplies the Baringo with the North- 

 ern Nyarus — the southern effluent of the same name 

 being clearly an influent. Nyarus thus corresponds with 

 the old Thumbiri, Tubirih, and Meri, afterwards called 

 Achua, Usua, and Asua, words probably corrupted from 

 Nyarus. 



The map of 1864, printed by Mr now Sir Samuel Baker 

 in the Proceedings of the Royal Geographical Society, 

 affirms the Asua to have been a dry channel 150 yards wide 

 when he crossed it, in Jan. 9, 1864, but rolling 15 feet deep 

 in the wet season. He can hardly be speaking of the drain 

 from the Baringo Lake, which must be large and perennial, 

 and which therefore must be sought farther north, unless it 

 anastomoses with some other stream. M. d'Arnaud, the 

 French engineer sent in 1840-1841 by Mohammed Ali 

 Pasha to explore the Upper Nile, reported (Journal Boyal 

 Geographical Society, vol. xviii. p. 73) that about 30 leagues 

 south of where the expedition was stopped by shallow water 

 in N. lat. 4° 42' 42", and therefore in N. lat. 3° 12', the 

 several branches unite, the chief one flowing from the east. 



The Baringo Palus must act reservoir to the whole N. 

 Western declivities of Doenyo Ebor, whose snows have given 

 it a name. Ptolemy (iv. 8) distinctly mentions the x(° va s> 

 or (melted) snows which feed the Nile ; and though he 

 places them in S. lat. 12? 30', he is correct as to the exist-
