‘Average for 1892 and 1898.........| ...... : 1.42 


a. The amount of fat for one pound of casein in cheese made 
from normal milk varied from 1.27 to 1.6 pounds and averaged 
1.42 pounds during the seasons of 1892 and 1893. 
6. In only ten cases, once in 1892 and once in 1893, did 
cheese made from normal milk contain less than 1.3 pounds of 
fat for. one pound of casein and in no case was the ratio below 
1 iets 
c. Averaging the individual results of the two seasons’ work 
as below, we can see how the variations were distributed:

It will be seen that nearly 90 per cent of the results are © 
within one-tenth of the average and the variation would have — 
been within still narrower limits had it not been for the abnormal 
conditions prevailing in July and August. . 
d. From the results of our two years’ work it appears fairly — 
settled that, in the case of cheese made from the normal mixed — 
milk of herds of cows, the fat seldom falls below 1.3 pounds for 
one pound of casein. The special bearing that this fact has _ 
upon the identification of cheese made from skimmed milk will — © 
be considered later. ene
