10. Relation of Fat to Total Solids in Cheese Made From 
Normal and Skimmed Milk. 
We have seen above that the relation of fat to casein in cheese 
probably furnishes a means of distinguishing skim-milk cheese 
from whole milk cheese. The question arises as to whether we 
can find other relations between the constituents of cheese which 
promise a more satisfactory basis for making such distinction. A 
careful study has been made of every experiment during the 
season of the relation existing between the fat and total solids, 
of the relation existing between the fat and the solids not fat, 
and also of the relation existing between the total solids and the 
solids not fat. The result of the study has not appeared to justify — 

the publication and discussion of the data, since none of these ~ , 
relations appear to be so uniform and sharply defined as to per- . 
mit of their use for distinguishing whole milk and skim-milk 
cheese. In general, it was found that in whole milk cheese, the ~ 
fat always exceeded the solids not fat, but this was also found to 
be true of some skim-milk cheese. So far as our study goes, no 
relation appears to be so sensitive and so easily affected by skim- — 
ming as the relation of the fat to the casein. 
II, General Summary of Results in Regard to Composition of 
Green Cheese. 
1. Pounds of water in 100 pounds of cheese: 
The water in 100 pounds of cheese varied during the season 
from 33.50 pounds to 42.90 pounds, and averaged 36.46 pounds. 
It was the most variable constituent of the cheese. 
2. Pounds of fat in 100 pounds of cheese: 
The fat in 100 pounds of cheese varied during the season from 
30.84 pounds to 37.24 pounds, and averaged 33.33 pounds. 
3. Pounds of casein and albumen in 100 pounds of cheese: 
The casein and albumen in 100 pounds of cheese varied during — : | 
the season from 22.11 pounds to 26.10 pounds, and aver Ss 
24.25 pounds. 
4, Pounds of casein in 100 pounds of cheese: 
The insoluble casein in 100 pounds of green cheese varied — 
from 20.67 pounds to 24.387 pounds, and averaged 22.68 pounds.
