Dairy Bacteriology. — I, Bacteriology of milk, W. Ste\'enson {Trans. High- 

 land and Agr. Soc. Scot., 5. ser., 29 {1917), pp. 153-181). — This article treats in 

 a popular way of the bacteriology of milk and briefly describes a few of the 

 more common species of each of the main groups of bacteria ordinarily found in 

 milk, indicating the main characteristics of each, the effects produced, and the 

 usual sources of infection. Simple directions are given for the control of bac- 

 terial growth in milk and for dealing with faults in milk. 



Investigation of conditions affecting' the content of water in butter, with 

 the use of various types of chums, L. P. Rosengren {K. Landtbr. Akad. 

 Handl. och Tidskr., 55 {1916), No. 4, pp. 249-263).— This is a comparison of 

 various types of churns and of the influence of salt on the water content of 

 butter. 



It is noted that if the water content is too large the butter must be re- 

 worked. Reworking decreases the water content of salted butter, but not of 

 sweet unsalted butter. The working of butter without washing reduces the 

 percentage of water. Washing decreases the water content of sweet cream 

 butter, but it does not change the water content of sour cream butter.
