In our work this past season we have not found a single instance 
in which the normal mixed milk of herds contained more casein 
and albumen than fat; and, moreover, we have not found a single 
instance in. which the milk contained as much casein and albumen 
as fat. In our investigation of breeds, we have found only one 
individual that regularly gave milk containing more casein and 
albumen than fat. .Some other individuals, when, twelve months 
or more along in lactation, were found to give milk of similar 
composition. 
The data secured this past season should be sufficient to afford 
us a fair basis for ascertaining the relation of fat to casein and 
albumen in average normal milk, as we find it in New York State. 
The table presented below contains a summary of the season’s 
results as applied to the relation of fat to casein and albumen in 
normal milk:

and in milk to which cream has been added.
