In the Second Rejjort of these Laboratories a note was made on the composition of the 
milk of cows of tlie Khartoum district, and also of that of goats. Attention was called to 
the fact that while in other countries the milk of goats was usually richer than that from 
cows, the same condition did not apparently hold for the Sudan. The few samples of cows’ 
milk which it was possible to obtain ipi to that time were quite as rich as that from goats. 
The average composition of the milk of goats examined and reported upon was : 
'I’otal solids Fat Solids uot fat 
14-20 4-60 9-GO per cent. 
These figures are the average of four samples collected in October. The average of 
three samples of cows’ milk collected at the same time was; 
Total solids Fat Solids not fat 
14-84 -5-7-3 9-09 
which indicated an appreciably greater richness in both total solids and fat. 
It was not possible to obtain authentic samples of cows’ milk for all the months in 
the year, but the following samples from a herd on the government farm, collected during the 
months of February, March and April, afforded results not materially different from those 
of the previous October. There is no indication, either in these figures nor in the exjjerience 
of those who have had to do with the cows’ milk of the Sudan, that there is any appreciable 
seasonal variation in the composition of milk such as obtains in other countries. 
The yield of milk in hot countries is probably always less, but the milk is more 
concentrated.

Adulteration of milk, Ijy addition of water, is still extensively practised; and as the 
water which may be used is anything hut above suspicion the state of affairs is one which 
calls for remedy. The greatest danger lies in the want of cleanliness on the part of those 
who handle the milk, a matter with which it is obviously very difficult to deal in a native 
population such as this.
