I only saw the Egyptian official on two occasions at Gedaref, and his peripheral blood showed no malaria, but marked leucopenia; splenic puncture was absolutely refused.

These cases are IV., V. and VI. 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.

The possibility of the introduction of the disease by Abysstnians 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 suspicious 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 number of local cases are four

proved, two suspicious—all fatal.

2. GALLABAT is constantly full of Abyssinians. Five suspicious cases, three already

fatal. I also saw many children with enormous spleens, but malaria is rampant here

during and after the rains.

3. GEDAREF. Comparatively few Abyssinians; the Mamour being able to collect

only thirteen men for my examination. No known cases.
