in a very general way, ordinary milks have about the following 

 general composition : — 



We do not claim that this is absolutely accurate, but it is 

 approximately so, and near enough for the purposes of the use of 

 the Babcock tester in connection with the sale of milk of the 

 statute standard. The statute standard of milk seven months in 

 the year is 13 per cent of total solids, and from the above table 

 we see that such milk would ordinarily have about the following 

 composition : — 



Fat, . 



Solids not fat,. 



Total, 



3.70 

 9.30 



13.00 



Five months in the year the statute standard is 12 per cent, which, 

 if normal, is made up about as follows : — 



Fat 3.00 



Solids not fat 9.00 



Total, 



12.00 



These facts are embodied in the statute standard as passed by 

 the Legislature last winter, which says : — 



In all prosecutions under this chapter, if the milk is shown upon 

 analysis to contain less than thirteen per cent, of milk solids, or to contain 

 less than nine and three tenths per cent, of milk solids exclusive of fat, 

 or to contain less than three and seven tenths per cent, of fat, it shall be 

 deemed for the purposes of this act to be not of good standard quality, 

 except during the months of April, May, June, July and August, when 

 milk containing less than twelve per cent of milk solids, or less than nine 

 per cent of milk solids exclusive of fat, or less than three per cent, of fat, 

 shall be deemed to be not of good standard quality. 



The Babcock tester gives only the amount of fat in milk, but 

 from the above it will be seen that the fat is the element which 

 varies the most, and that the amount of fat is practically the key 

 to the situation. Milk having 3.70 per cent of fat will be up to
