308 Appendixes 



Brassica. Kajanus has investigated the genetics of 

 seme species of this genus, particularly napus and rapa and 

 their hybrids. He confirms older observations as to the 

 production of lumpy outgrowths (resembling "finger and 

 toe") as the result of certain such crosses, and in this 

 respect he found remarkable differences between reciprocals. 

 Zts. f. ind. Abstam., 1912, vi. p. 217. 



Cotton. Leake found the sympodial habit partially 

 dominant over the monopodial, with many forms of blending 

 between the two types. The inheritance of the leaf-shapes 

 was determined by a special method of measurement and 

 it was found that certain shapes were always heterozygous. 

 Leake, H. M., Jour. Gen., 1911, p. 205. 



Tomato. Genetic properties of several characters, 

 especially leaf-shape, investigated by Groth, A., Bulletins 

 238 and 239. New Jersey Agricultural Station, 1911. 



Cattle. Evidence as to inheritance of long and short 

 legs, and red or black colour in Dexter Kerry. Wilson, J., 

 Sci. Proc. R. Dublin Soc. y xu. 1909, p. i. 



Dogs. Genetics of several characters investigated by 

 A. Lang, Zts. f. ind. Abstammungslehre, in. 1910, p. i. 



Colour-Characters. Plants. 



Antirrhinum. Full and minute analysis of colours, for 

 the most part confirming Miss Wheldale's results, and 

 adding a remarkable case of coupling (see later, p. 318). 

 Baur, E., Zts. f. ind. Abst., 1910, in. p. 34. An account 

 of Mendelian heredity in the case of a cross between distinct 

 species of this genus was given by Baur at the Genetics 

 Conference, Paris, 1911, but publication has not yet been 

 made. 



Cotton. Curious case of complete correlation between 

 small size of petals and white colour, and large size and 

 yellow colour. Leake, H. M., Jour. Gen., i. 1911, p. 241. 



Digitalis. Analysis of flower-colour, with evidence that 

 white may be a dominant. Keeble, Pellew, and Jones, 

 W. N., New Phytologist, ix. 1910, p. 68. 



Helianthus. Discovery of a new red-flowered variety. 

 The heterozygote with the yellow type is intermediate in 

 colour. Cockerell, T. D. A., Pop. Sci. Monthly, 1912,
