Esten, W. M. and C. J. Mason. Sources of Bacteria in Milk. 



(Bull. 51. Storss, Connecticut), p. 65—109, figs. 1—23, vign. on 



Cover, 1908.) 



Bacteria that get into milk classed in 4 main groups and 16 

 classes. About 80 percent of the bacteria that get into milk are 

 indifferent forms not exerting any harmful action on milk. An 

 interesting table is given showing the sources of infection for the 

 16 classes of bacteria; only five are given as originating inside of 

 the udder. Micvococcus lactis varians (formerly called Staphylococciis 

 pvogenes aureus), a pathogenic form occurs in the udder not infre- 

 quently. Hay bacteria are treated in some detail. This bulletin is 

 in the main a populär summary of the much longer paper by Esten 

 and Stocking, Classification of Dairy Bacteria, published in the 

 Annual Report for 1906 Storrs (Connecticut) Agric. Exp. Station.

 Equisetum hyemale. (Ohio Nat. VIT. p. 121-126. Pls. 9—10. 1907.) 

 The sporangium is found to be eusporangiate. The superficial 

 sporangium initial divides periclinally, only the outer half giving 

 rise to sporogenous tissue. The tapetum has its origin in the cells 

 surrounding the sporogenous mass. M. A. Chrysler.
