_ second, when the milk was richest in fat; while the largest pro- 
portion of fat lost was in April or May when the amount of fat 
in the milk was least. The results of our two years’ work all go. 
to show that the proportion of fat lost in cheese-making is quite 
independent of the amount of fat in the milk. The variations 
that occur in loss of fat are due either to the conditions of the 
milk or to some special conditions employed in manufacture.
