mode of procedure : Evaporate a given amount of milk on a 
water bath for three hours, and the loss of weight represents the 
amount of water it contained ; that left in the pan is total solids. 
To ascertain the amount of fat, wash with ether till it ceases to 
lose weight again ; this may be repeated. Ether will only take 
up the fatty products, then the solids, not fat, are left. To de¬ 
termine amount of caseine, wash the residue in pan with strong 
alcohol cold, then with hot water, and filter ; what goes through 
the filter is sugar and chlorides; that on the filter is caseine; that 
in the pan solids not soluble. He scouted the idea that our ani¬ 
mals, in drinking water, etc., containing the genps of scarlet fever, 
etc., carried them through their system and to the milk, and thus

closets and elsewhere, the milk became the conveyance for these 
germs, and even a cultivator of them. 
Much discussion followed on the milk of pleuro-pneumonia 
cattle, and reference was made to milk from animals affected with 
tuberculosis.

before the meeting by Dr. Rogers. It proved to be fresh, sweet

purposes in the winter. This was cut green and placed in a pit, 
covered with boards, and then about five feet of dirt placed 
over it. 
On motion, the meeting adjourned to the infirmary of Dr.
