He says that European market milk has been found to contain a 
greater average bacterial count, ranging from 5,000,000 to 10,000,000, 
and frequently 20,000,000 to 180,000,000. 
Proskauer, Seligmann, and Croner,® 1907, found that Danish milk 
sold in Berlin in the summer varied, in round numbers, between 
5,000,000 bacteria per cubic centimeter and innumerable quantities. 
In the winter this milk contained about 2,140,000 bacteria per cubic 
centimeter. 
The same investigators found that the market milk of Berlin 
averaged 3,500,000 bacteria per cubic centimeter in summer and 
567,000 in winter. 
Knox and Schorer, 6 1907, state that several summers ago the quality 
of the milk supplied to the working classes in Baltimore was studied 
during two successive summers at. the laboratory of the Thomas 
Wilson Sanitarium. Much of the milk on sale at the small stores 
was shown to be unfit for consumption, having a high bacterial count. 
It will thus be seen that the general market milk of Washington, 
as well as that of other large American and European cities, is 
worthy the serious attention of health officers as far as excessive 
bacterial contamination is concerned.
