Bacteriology and the dairy. 
Dairy products constitute a valuable source of wealth in the United 
States, and several colleges have already established dairy schools. 
Wisconsin is not only in the front rank of s ates in the value of its 
milk products, but was the first to establish a thoroughly equipped 
dairy school. Shortly after that was done Dr. Russell was put in 
charge of the bacteriological work of the experiment station and the 
dairy school, and much important work is now in progress. The ex- 
periment station now conducts 4 creamery throughout the year, which 
gives opportunity for bacteriological and other experiments on a com- 
— scale. A science so important to the dairymen of course 
mands a place in the instruction of the dairy school. Finding no 
wiles small manual of bacteriology in its relation to the dairy, Dr 
Russell set himself to write one.! It is divided into three parts, the 
first giving a summary account of the bacteria in general, while parts 
two and three are concerned with bacteria in their relation to milk, 
and bacteria in their relation to milk products. The author’s endeavor 
avoided overburdening his text with references to literature, though 
authority for many facts is cited 
We hope that the conciseness, simplicity, and accuracy of this little 
manual, as well as its commercial bearing, will insure it a wide sale, 
and that the first edition will soon be exhausted. This edition has 
been purposely kept small so that the book may be kept up to date 
in the rapidly advancing science of which it treats.
