Dr Chapman pointed out that at certain seasons of the year 

 it was not uncommim to find .samples of milk which contained 

 less than 85 per cent, solids not fat. It was also known that 

 the milk fnm^ certain cows and from certain races of cows 

 yielded less than 8-5 per cent, solids not fat. It was therefore 

 erroneous to conclude that a milk containing less than 8-5 per 

 cent, soiids not fat had necessarily been adulterated with watei'. 

 In the case of certain Durham cows, it was noted that although 

 the amount of solids not fat was less than 8;"3 per cent, the 

 amount of fat was high, viz , 4 G per cent. 8uch milks have a 

 high caloric value, and are therefore valuable as foods.
