mixture taken. Samples of the milk IVom the ten cows fed on 
se waged grass were taken in the same way. These samples were 
immediately put into bottles filled up to the corks and sealed 
down, and sent off the same evening by railway to Professor Way 
for analysis." 
[There were in all 13 samples of the milk from the cows fed 
on unsewaged grass, and 15 of that from those fed on sewaged 
grass, taken as above described, and the results of the analyses of 
the 28 samples are given in the Appendix to the Report of the 
Commission. *] 
"In the following Summary Table (IX.) are given, — the mean 
composition of nine samples of milk taken from the cows fed on 
unsewaged grass alone, and of ten taken from those fed on 
sewaged grass alone ; the mean of four samples from each lot of 
cows during the concluding four weeks, when they had oilcake 
as well as grass ; and also the composition of the milk of the ten 
cows taken on one occasion during the experiment, when, owing 
to a deficiency of the experimental grass at the time, they had, 
for a short time, a mixture of sewaged Italian rye-grass and 
clover, and a little oilcake besides.
