SECOND OBJECTION ANSWERED. 3Q§ 



212*' (F.). Moreover, the observations of Sir 

 Samuel Baker, carefully compared with those of 

 the second expedition, decisively proved that 

 1000 feet must be added, placing the Tanganyika 

 and the Nyanza on nearly the same level. 

 Again, Dr Livingstone reports from Bangweolo 

 (July, 1868) of the Liemba Lake, that he would 

 have set it down as an arm of the Tanganyika, 

 but that its surface is 2800 feet above sea-level, 

 ' while Speke makes it 1844 only.' Finally, the 

 great African traveller, who has now been long 

 resident in the regions west of the Tanganyika 

 Lake, always writes of it as if he considered the 

 connection between it and the Luta Xzige 

 established. Thus the altitude of Lake Tangan- 

 yika was raised to 2800 feet, which would easily 

 carry its waters to the Xile. ' It may appear 

 strange,' as Mr Galtonhas remarked, ' that there 

 should be an error of a thousand feet of altitude 

 suspected in the observations of an explorer, 

 but the method of operating in uncivilized 

 countries is quite different from that employed 

 at home.' Evidently Capt. Speke allowed the 

 altitude of the lake to lie uncorrected for the 

 same reason which made him raise his ' Lunae 

 montes.' This will also answer M. Parthey (June 

 2, 1864, Uoyal Academy of Sciences, Berlin).
