103 analyses of 55 herds made in July and August, 1882, gave: 



Solids. Fat. 



Average, 12.08 4.03 



Maximum, 13.83 5.63 



Minimum, 9.19 2.60 



The average of 208 analyses of herd milk is : 



Solids, 12.40 



Fat, 4.02 



The results just given show that in the herd-milk examined at 

 this Station, solids varied between 14.4 and 9.8 per cent., and fat 

 between 5.6 and 2.6 per cent. In only one case were the solids 

 below 10 per cent, and in that instance the fat was 3.1 per cent. 

 In 6 cases solids were between 10.0 and 10.5, the fat ranging 

 from 3.1 to 3,5. (Two of these cases represent milk of the same 

 herd.) In 6 cases solids were between 10.5 and 11.0, the fat 

 ranging from 2.8 to 3.9. (One case is the same herd that gave 

 solids below 10 per cent.) In 19 cases the solids fell between 11.0 

 and 11.5, the fat between 2.6 and 4.5. In 27 cases solids ranged 

 between 11.5 and 12.0, fat between 3.3 and 4.1 per cent. In the 

 other 150 cases the solids were above 12.0 per cent., and the fat 

 ranged from 3.4 per cent, upwards.

 Unfortunately it was not possible to make determinations of 

 specific gravity in the samples here examined. In no case was 

 there any apparent sickness among the cows. The larger number 

 of the cows in these herds were grade Jerseys ; but there was 

 also a considerable number of natives, Jersey thoroughbreds and 

 Guernseys. 



There is no absohde certainty that some of these samples were 

 not either watered or diluted with skimmed milk. It is hard to 

 believe that a milk with only 9.8 per cent, of solids has not been 

 tampered with ; on the other hand, it is not reasonable to suspect 

 that the milk of between 50 and 60 herds of cows .has been sys- 

 tematically " doctored," to reduce the solids below 12 per cent., 

 the minimum figure below which it has been assumed by some
