found it commoner than malaria in 

 cases that have come "up" for 

 treatment; new-comers to the 

 district seem to suffer the worst. 

 My cook developed it after being 

 here 12 days. The number of 

 parasites found in the blood do 

 not seem to have much relation to 

 the severity of the attack. My cook 

 had two wery sharp attacks - he was 

 very ill. Temperature 103-1 04° and 

 spleen down to the umbilicus but the 

 parasites in the blood were scanty, 

 one or two to a slide, whilst a 

 little girl who came "up" feeling 

 comparatively well (slight headache 

 and temperature 102) had numerous 

 parasites in the blood, two in some 

 fields. The parasites seem to be a 

 good deal in length and the number 

 of curves, 14, 20th; some have few 

 curves whilst others eight or nine; 

 the latter probably being really two 

 parasites "end to end". The ticks 

 transmitted are all, I think, 

 Ornithodoros moubata. 



Dr. George Wallace (6, V. 1909) sent ticks to be identified, and being all 

 common species, they were returned to him. They were all collected in 

 Mauritius, and comprised:- 



Amblyomma variegatum cf's, ?'s, N's off cattle 16-18. XI .1908 

 Rhipicephalus evertsi ^''s, ?'s off cattle, goats 18.XI-6.XII .1908 

 Rhipicephalus appendiculatus cf, ? off cow 18. XI. 1908
