a. In normal milk, which contained fat varying from 3.04 to 
4.6 per cent, the casein varied from 1.93 to 3 percent. The fat 
averaged 3.75 per cent and the casein 2.46 per cent. 
b. In no case did the normal milk during the two seasons con- 
tain less than 1.38 pounds of fat for'one pound of casein or more 
than 1.78 pounds of fat for one pound of casein. 
c. Averaging the individual results of our two seasons’ work as 
below, we can see how the variations were distributed :

It will be seen that over eighty per cent of these results are 
within one-tenth of the average and, it is safe to say, that over 
ninety per cent would have been within these limits if the condi- 
tions of the past season had been normal. 
d. During the first four months the average ratio was very 
nearly 1.5. The fat began to increase, relative to the casein, 
about the middle of July and continued throughout August; in 
September the ratio began to diminish and in October diminished
