MILK ANALYSES. 
N continuation of our remarks on 
this subject in last month's issue 
of the Agricultural Magazine we 
now give the following .analyses 
of a sample of milk from the 
Ceylon Government Dairy, by Mr. Cochran, the 
city analyst : —

(Signed) M. Cochran, f.c.s., 
Citg Analyst. 
In sending the results of his analysis, 
.Mr. Cochran writes: — " The analysis shows it 
(the sample) to be very considerably richer than 
the average of English milk." This may be seen 
by comparing the present analysis with the 
percentage composition of the miik of English 
COWS Lpvn in our last article on milk analyses. 
Ii a notorious fact that the ordinary milk of 
the peripatetic milkman is often adulterated to 
a more or less extent with such substances as 
buffalo's milk, coconut milk, sugar, flour and 
condensed milk, and, last but not least, water. 
In the valuable contribution (referred to in our 
last issue) made by Mr. Cochran on the composi- 
tion of Colombo milk, he says : — ■" I got a freind, 
on three different occasions to purchase samples 
of milk from passing milk-sellers, just as it is 
sold to the people of Colombo who do not keep 
cows for their own supply. The first of these 
samples gave the following results : —

" Basing the calculation upon our 8 per cent 
minimum of non-fatty solids, this sample of milk 
contained 44 - 6 per cent of added water, i.e., the 
milk had been diluted with nearly its own 
volume of water. 
"The following was the composition of the other 
two samples of bought milk : — ■

" Neither of these can be regarded as genuine 
cow's milk. If the 8 per cent solids-not-fat 
formula be adopted, the one marked A could not 
have containedjmore than 77 per cent, and the one 
marked B more than 43-75 per cent of genuine 
cow's milk respectively. lam of opinion, how- 
ever, that these were not simply samples of
