Analysis 
of cases 
I only saw the Egyptian official on two occasions at Geclaref, and his peripheral blood 
showed no malaria, but marked leucop®nia; splenic puncture was absolutely refused. 
These cases are lY., Y. and Yl. in Table “ B," and it is to be noted that the master and 
male servant became ill in August, 1907 (however a malarial period), the female servant a 
little later. The male servant died on December 25th, 1907, the female servant on 
December 27th, 1907, and the master in February, 1908 ; the summaries of their histories 
are given in the Table. 
Tlie possihilitij of the introduction of the disease In/ Abyssinians has been enquired into, and 
it certainly is striking that out of the eight positive cases, three were Abyssinians (37’5 per 
cent.), and of the thirteen suspicions cases three were of this nationality. Considering their 
comparatively small number it is a suggestive fact. 
I inspected all the Abyssinian men who could be collected at Gedaref, but found all 
healthy, except one suffering from malaria. 
These facts were ascertained about the following towns ;—• 
1. KASSALA. Many Abyssinians live here, and the nnmher of local cases are four 
proved, two suspicious—all fatal. 
2. GALLABAT is constantly full of Abyssinians. Five suspicious cases, three alreadj’ 
fatal. I also saw many children with enormous spleens, but malaria is rampant here 
during and after the rains. 
3. GEDABEF. Comparatively few Abyssinians; the Mainour being able to collect 
only thirteen men for my examination. No known cases.
