decreasing at first rapidly, then more slowly, throughout prenatal and post- 

 natal life. . . . During prenatal life the total weight of the body and the

The wild and domesticated Suidae of Sardinia and Corsica, E. L. Tboues- 

 SART and E. G. Dehaut (Conipt. Rend. Acad. Sci. [Paris], 153 {1911), No. 8,

Objects and results of swine registration, C. A. Willson (Amer. Breeders 

 Assoc. [Proc.'\, 6 (1910), pp. 3-il-3/f9). — A summary of the aims of the different 

 swine breeders' associations iu the United States, in which a comparison as to 

 the stress laid upon each part of the hog, as shown by the score card of the 

 record associations, is presented in tabular form. The comparative results of 

 measuring the value of an animal by its pedigree and by its individual char- 

 acteristics are discussed, and it is pointed out that if a pedigree is to be of 

 value in the future it must contain more information than it does at present. 

 An advanced registi'y for swine is advocated in which prolificacy and other 

 desirable qualifications can be recorded.

Data on the direction of the cross, C. A. Rogers (Amer. Breeders Assoc. 

 [Proc], 6 (1910), pp. Ii55-If59, fig. 1). — Experiments are reported with recipro- 

 cal ci'osses of White Leghorns and Barred Plymouth Rocks. A pen of pure 

 White Leghorns and one of pure Barred Plymouth Rocks were kept as checks 

 for comparison with the crosses. Apparently the male had more influence on 

 the size of the egg, size of the day-old chick, nature of the feathering of the 

 chick, size of the offspring, and the style of the feathering and furnishings of 

 the offspring, whereas the influence of the female was stronger on the less ap- 

 parent characteristics such as the rapidity of development, rate of maturing, 

 and prolificacy. 



Researches on the bacterial flora of old eggs, A. Chretien (Hyg. Viande et 

 La it, 5 (1911), No. 9, pp. 517-528). — The eggs examined were known on the 

 market as stale but not spoiled. Out of 52, 20 were found to be free from 

 microbes. In 12 cases the germs were found in the yolk, in 6 cases in the 

 albumin, and in 14 cases in both yolk and albumin. Besides a number of 

 unidentified species there were moulds. Streptococci, Staphylococci, the coli 

 type, the paracoli type, Bacillus fiuorescens nonliquefaciens, and B. prodigiosus.
