errors of sampling inherent in work in genetics. Several illustrations of using 

 the method are given. 



Simplification of Mendelian formulas, W. E. Castle (Amer. Nat., J^l (1913), 

 No. 555, pp. 170-1S2). — The proposals for the simplification of Mendelian ter- 

 minology are summarized briefly as follows: "(1) To abolish the current dual 

 tei-minology and use only 1 symbol, where a single variation from the normal 

 is involved. (2) To use a small letter to designate the factor responsible for 

 V. variation which is recessive in crosses with the normal. (3) To use a capi- 

 tal letter to designate the factor responsible for a variation which is dominant 

 in crosses with the normal." 



The principles of stock breeding, J. Wilson {London, 1912, pp. VI+lJt6, 

 figs. 2). — This book treats principally of Mendel's law and its possible appli- 

 cation in the breeding of live stock. Some of the work already done on in- 

 hei'itance of color in horses and cattle and on inheritance of the milk yield 

 in cows is discussed in detail in order to understand how the Mendelian dis- 

 covery may advance our knowledge of inheritance in live stock, and at the 

 same time indicate by example what may be possible by way of breeding in 

 the future. There is a brief treatment of pre-Mendelian theories regarding 

 the value of pedigree and other significant factors. 



The descent of animals, J. A. Jessen (Amer. Jour. Vet. Med., S (191S), 

 No. 3, pp. 133-139). — This is a paper read at the meeting of the Missouri 

 Valley Veterinary Association, January, 1913. The problems of inheritance 

 are discussed, and it is suggested that veterinarians and practical stock breed- 

 ers should pay more attention to these problems in order to proceed more 

 intelligently in breeding operations. 



Biology of cattle, W. Wilson (Verliandl. Internat. Zool. Kong. Gras, 8 

 (1910), pp. 939-9Jf8). — Brief discussions are given of factors concerned in the 

 domestication of cattle, the adaptability of certain breeds for special purposes, 

 and tendencies in the improvement of our breeds of cattle. 



Inheritance of the poll character in cattle, W. J. Spillman (1913, pp. 8, 

 figs. S). — This is a paper read at the annual meeting of the American Polled 

 Jersey Cattle Company, 1913, on the practical value of Mendelism as applied 

 to the inheritance of horns in cattle. 



The relation between body measurements and the w^eight of the heart and 

 lungs in the Chiana breed of cattle and a comparison between the Chiana 

 and the Romagna breeds, C. Pncci (Mod. Zooiatro, 1910; Jahrb. Wiss. u. 

 Prakt. Tierzucht, 7 (1912), pp. 117-131, figs. 5). — ^As a result of measurements 

 it is concluded that the absolute weight and the relative weight of the lungs 

 and heart is on the average greater in the oxen of the Romagna breed than in 

 the Chiana. Other conclusions in regard to comparative measurements of form 

 are given. 



Contribution to our knowledge of the Tarentaise cattle from a zootech- 

 nical and industrial standpoint, P. Hoffmann (Mitt. Landw. Lehrkanz. K. K. 

 Hochsch. Bodenkul. Wien. 1 (1913), No. 3, pp. S09-3S7, pis. 3).— This discusses 

 the origin, characteristics, and value for meat and milk production of this 

 breed of cattle. They are especially adapted to dry climates, and their strong 

 constitution makes them valuable animals for crossing with improved types. 



The author is inclined to think that they are descendants of the original 

 cattle of the ancient pile works of Switzerland, somewhat modified by environ- 

 ment, and not as thought by Boucher " a cross between the Jurassic and Alpine 

 breeds. Measurements of a number of animals are given. 



On the determination of hemoglobin in cattle, Dettweileb (Fiihling's 

 Landw. Ztg., 61 (1912), No. 6, pp. 193-206).— The blood of cattle at pasture and 



•Jour. M€d. V€t. et Zootech., 53 (1902), pp. 214-224, 257-271, 335-347.
