observations were taken at Purkiss' Station, Berkeley- 

 Bay, at 6 p.m., the 12th of January, 1894 (temperature 

 82°). They were 2047 and 204*8, which, allowing instru- 

 mental corrections, gave a mean of 205, corresponding to 

 3,652 feet. I assumed the level of the Victoria Nyanza to 

 be 3,900 feet. 



The following series taken at Matschakos on the 5th and 

 6th of December at a (mean) temperature of 66°.

gave a mean, after correcting diurnal variation and instru- 

 mental errors, of 202*55, corresponding to 5,043 feet. 



From this one proceeds thus : 5,043 feet

This corrected for temperature is 1,521 

 To which add true altitude 3,900 



5,421 



This should be the true altitude of Matschakos, if 3,900 

 feet is that of the Victoria Nyanza. 



The Kailway Survey gives for Matschakos, 5,400 feet 

 and for the Victoria Nyanza 3,820 feet, which makes a 

 difference between the results of 59 feet. 



I also tested my results with Kinani, for which I obtained, 

 taking the Victoria as 3,900 feet, an altitude of 2,109 feet. 

 That of the Kailway Survey is 2,200 feet— that is, 3,820 

 —2,200, or 1,620 feet below the Nyanza ; my result was 

 3,900—2,109 = 1,791 feet, so that, in this case, the result
