 situations. 



Fever of the ordinary Uganda type certainly 

 prevails up to a height of 5,000 feet all round the 

 base of the mountain. I do not think that there 

 is any true malarial fever above this altitude. I 

 myself did actually suffer severely from fever when 

 living at about 6,000 feet, but this had been con- 

 tracted on the plains. 



On the other hand, in the Colony zone, at a 

 height of 5,000 to 7,000 feet, there is a curious 

 kind of rheumatism, or " dengue ' fever, which 

 affected many of my men. It seemed to begin

 legs, which were accompanied by great lassitude 

 and fatigue. This appears to become acute at 

 night, and in the early morning and during the 

 day seems to disappear almost entirely. 



I found that the ordinary treatment for malarial 

 fever was far the best remedy for this " dengue," 

 or rheumatism. 



The chief objection to Ruwenzori as a sana-

 it is moisture that is dangerous, and on Ruwenzori

The rainfall must be very heavy, for though 

 I had no means of actually measuring it, rain 

 fell on about 40 days out of the 126 which I 

 spent upon the mountain. There is, however, a 

 great difference in different valleys. The Wimi
