DEFICIENT SOLIDS. 51 



"My object is by no means to raise the cry that 

 the standard adopted by the Society is too high; on 

 the contrary, I think it is very judiciously fixed, but in 

 upholding the standard of purity it should not be for- 

 gotten that the cows have never been asked for, nor 

 given their assent to it, and that they will at times pro- 

 duce milk below standard. A bad season for hay- 

 making is, in my experience, almost invariably fol- 

 lowed by a particularly low depression in the quality 

 of milk, toward the end of winter. Should the win- 

 ter be of unusual severity and length, the depression 

 will be still more marked. Long spells of cold and 

 wet, as well as of heat and drought, during the time 

 when cows are kept on pasture, also unfavorably influ- 

 ence the quality and, I may add, quantity of milk." 



Deficient solids. The following are some instances 

 of deficiency of solids in milk known to be genuine.
