Canary breeding.— A partial analysis of records from 1891 to 1909, A. 11. 

 Galloway {JHomrtrihu, 7 (190!)), No. 7-2, pp. 1-J,2, ph. 5, figs. /,).— This paper 

 contains the results of 17 years' breeding with many types of canaries. The 

 author considers thai divcisily of type has arisen from crosses between cinna- 

 mon sports and the wild green bird. This theory is advanced from (1) a 

 study of wild sports in nature and in confinement, (2) cinnamon and cinnamon 

 bred hybrids which freipiontly show characteristics of canary varieties arising 

 de novo, l?.) collateral evidence of a similar nature in poultry and i)igeons, and 

 from (4) a sludy of the earliest canary literature. 



Mendelian inheritance in canaries is discussed at length. Dark-eye and pinli- 

 eye are found to behave generally in Mendelian fashion, for it is evident that 

 there is a homozygous type of dark-eye canary and also a heterozygous or 

 impure form occurring in the male as well as the female. There is some evi- 

 dence that the female of the homozygous type of dark-eye canary is homozygous 

 as well as the male. Other characters which are seen to behave as recessives 

 are buffness and crest -l>red plain-headedness; their corresponding qualities (yel- 

 lowness and crestedness) exhibit more or less imperfect dominance. The 

 majority of crests appear to be heterozygous with respect to crest. 



Some of the results obtained by Davenport (K. S. R., 20, p. 1072) are stated 

 to be different from those of the author, because of the breeding stock used by 

 Davenport and his interpretation of fancy points. The need for a more strict 

 definition of characters and their nomenclature is indicated. Colored plates 

 and engravings are used to assist in improving the tei-minology of canary 

 fanciers. 



Note on partial leucosis in a hen, W. 0. Finch (Biometrika, 7 (1909), No. 1-2, 

 pp. 23.'f-236, /(V/.s. .5). — An account of birds which were obtained by a cross 

 between an Indian game and a true Houdan. One hen turned from black to 

 spotted in her first year, the spots since that time having diminished annually. 

 Another hen has been once black, once white, then once spotted, and again 

 white. 



The role of inorganic phosphorus in the nutrition of animals, E, B. Hart, 

 E. V. McCoLLUM, and J. G. Fuller (Wisconsin Sta. Research Bui. 1, pp. 38, figs. 

 7). — The investigations reported have been noted from another source (E. S. R., 

 21, p. 69). 



The relative value of feeding stuffs, F. T. Siiutt (Rpt. Select Standing Com. 

 Agr. null Colon. [Canada^, 1009, pp. 22-42). — Analyses are reported of molasses, 

 apple pomace, Paddy rice, by-products of corn, wheat, oats and peas, cotton-seed 

 and flaxseed meals, and mixed feeds. 



Registered feeding stuffs (Kansas Sta. Feeding Stuffs Bui. 4, PP- -i)- — This 

 contains a list of all feeding stuffs registered in the State for the year ending 

 June .30, 1010, and also a list of manufacturers of cotton-seed meal and condi- 

 niental feeds whose registrations have expired. 



The Wisconsin feeding stuff law, F. W. Woll ( Wisconsin Sta. Circ. Inform. 

 1, pp. 9). — This contains the text of the Wisconsin feeding stuff law as amended, 

 by the legislature of 1909, and comments thereon. Standards of pure feeds of 

 different kinds are suggested in order to aid manufacturers and dealers in 

 determining the guaranties under which their various feeds may safely be sold. 



A guide to the domesticated animals (other than horses), R. Lydekkeb 

 (London; Govt., 1908, pp. 5.'i, pis. 8, figs. 7). — A brief account of the different 

 types of domesticated animals, chiefly cattle, sheep, and dogs, represented by 

 specimens iu the British Museum.
