TYPES OF ClTY MILK 187 



physicians. This commission, by means of chemical and 

 bacteriological tests and sometimes by visits to the dairies, 

 insures itself that certain dairies produce milk of good

 purchased is that upon which the poorer classes in cities 

 largely depend. This is obtained from groceries, and is 

 bought in small quantities. This method of purchasing 

 is a necessity with the poorer classes who have no re- 

 frigerators, for in warm weather it is quite impossible to
