Some observations on homogenized milk and cream, H. B. Baldwin (Amer. 

 Jour. Pub. Health, 6 (1916), No. 8, pp. 862-864, figs. ^).— The author notes the 

 development and occasional fraudulent use of the process of homogenization in 

 the milk industry, and gives the results of two sets of measurements of fat 

 globules in samples of homogenized cream from two different machines working 

 under pressures of from 700 to 4,000 lbs. per square inch. , 



The degree of homogenization was found to be generally increased with the 

 pressure, and in one of the machines the destruction of fat globules was so 

 great that no spherical forms could be observed through a one-twelfth in. oil- 

 immersion objective. The diameter of most of the homogenized fat globules 

 ranged between 0.001 to 0.002 mm. in diameter, whereas the majority of normal 

 milk fat globules range in diameter from 0.005 to 0.006 mm. 



Condensed milk in Bermuda, S. W. Eells (V. S. Dept. Com., Com. Rpts., 

 No. 2Jfl {1916), pp. 168, 169).— The author states that Bermuda annually im- 

 ports about 720,000 cans of condensed milk, of which about 15 per cent is un- 

 sweetened or evaporated. On account of poor pastures and the cost of fodder 

 the prospects for the production of fresh milk on the islands are not good. 

 Evaporated milk stands the climate well. The American brands of unsweetened 

 condensed milk are considered best by most dealers, though there is a prejudice 

 among consumers in favor of Canadian and European brands. Nearly all the 

 sweetened condensed milk comes from Europe, but some is now imported from 

 Canada. 



Suggestions for the manufacture and marketing of creamery butter in the 

 ^uth, R. C. Potts and W. White {U. S. Dept. Agr., Off. Sec. Circ. 66 (1916), 

 pp. 11). — This circular contains practical suggestions on the management of 

 creameries and the manufacture and marketing of creamery butter in the South.

 laboratory at Lethbridge, Alberta (pp. 100, 101), including a report on Dourine 

 and the Complement-Fixation Test (pp. 101-119), by E. A. Watson; and a
