while Streptococci were comparatively rare. Various i'orms of Saccharomyces 

 were frequently found. Tlie colon bacillus was not common, and the liquefying 

 bacilli present were those commonly found in water. A number of doubtful 

 species were tested for their pathogenicity, but in no instance were the results 

 fatal to laboratory animals, and rarely was there a passing inflammation 

 produced. 



Some of the results are summarized as follows: "Provided the apparatus of 

 the milking machine is intelligently handled, and it is thoroughly attended to 

 as regards cle;uiliness and sterilization, its use does not interfere with the 

 general health of the cow or of the udder. The milking machine so used 

 does not lead to a greater bacterial contamination of the milk than does the 

 process of hand milking, even when conducted under the most approved condi- 

 tions, but on the contrary the average results show an improvement." 



The Copenhagen milk supply, J. H. Monrad {N. Y. Produce Rev. and Amer. 

 Cream., 3J, (1912), No. 7, pp. SJ/G, S-iS, 350, 352).— An account of a method of 

 furnishing a sanitary supply of milk to Coi)enhagen, which has had no epidemic 

 traceable to milk since 1901. Since 1880 the death rate of children has dropped 

 from 219 to 119 per 1,000, due in large part it is thought to the improvement 

 in the methods of handling milk. The translation of the text of the Copen- 

 hagen milk ordinance is given. 



Begulations governing the sale of milk in Prussia (Molk. Ztg. [Hildes- 

 heim], 26 (1912), No. 64, pp. 1202-1205).— This contains the text of the regu- 

 lations issued July, 1912, by the Minister of the Interior, Agriculture, and 

 Public Domain. 



Milk products in the Siebenburg' reg'ion of Hungary, F. Baintneb 

 (Kiserlet. Kozlem., 15 (1012), No. 2, pp. 227-268).— This reports analytical 

 data on cream, butter, buttermilk, cheese, and whey obtained from the milk of 

 sheep and buffalo. 



Measuring color: An oleo standard (Hoard's Dairyman, J/Jf (1912), No. 6, 

 p. 131). — ^A report of an examination by optical methods of numerous samples 

 of butter and oleomargarine. As the result of this work it is suggested that 

 the latter be deemed an imitation of butter only when it contains less than 

 55 per cent of white. 



Parchment paper for dairy use, M. Siegfeld (Molk. Ztg. [Hildesheim], 26 

 (1912), No. 60, pp. 1125, 1126). — ^The author reports analyses of 66 samples of 

 parchment papers sold for wrapping dairy products. The content of water- 

 soluble material ranged from 0.13 to 28.25 per cent, and the ash from 0.28 to 

 7.S9 per cent. Only 23 samples could be designated as of good quality when 

 judged by the standard advocated by Burr and Wolff (E. S. R., 23, p. 616). 



Factory arrangement, F. W. Culbertson et al. (N. Y. Produce Rev. and 

 Amer. Cream., 3// (1912), No. 7, pp. 364, 365, figs. 3).— This contains plans of 

 several cheese factories showing the arrangement of apparatus.

Principles of microbiology: A treatise on bacteria, fungi, and protozoa 

 pathogenic for domesticated animals, V. A. Mooee (Ithaca, N. Y., 1912, pp. 

 XI-\-506, figs. 101). — This volume has been prepared as a text-book for veter- 

 inary students beginning the study of microbiology. It is said to be the 

 outgrowth of a lecture course which accompanied laboratory work in bac- 

 teriology and protozoology. " In its preparation, the puiiwse has been to point 

 out the place and role of micro-organisms in nature ; to give the methods for their 

 study and identification ; to indicate the relation of certain species to animal 

 diseases; to give a description of the more important species pathogenic for
