 correcting the account previously given by Correns. 

 Marryat, D. C. E., Rep. Evol. Ctee. Roy. Soc., 1909, p. 32. 



Primula Sinensis. Genetics of colour-characters in 

 flowers and stems ; also of several structural characters. 

 Gregory, R. P., Jour. Gen. i. 1911, p. 73. 



Colour- Characters. Animals. 



Cattle. Wilson, J., "The colours of Highland Cattle," 

 Sci. Proc. R. Dublin Soc., 1909, xn. (N. S.) p. 66, contains 

 evidence as to the relations between dun, brindled, and 

 other colours hitherto little studied. 



Mice. Analysis of the coat-colours of mice having pink 

 eyes. Durham, F. M., Jour. Gen., i. 1911, p. 159. 



Analysis of coat-colours of mice in general with discussion 

 of the relation of the phenomena to those seen in other 

 rodents. Incidentally (p. 126) evidence is given as to a 

 case in which the factor for colour seemed to repel the 

 agouti factor. Hagedoorn, A., Zts. f. ind. Abstam., 1911, 

 vi. p. 99. 



Horse. Factors for the various colours provisionally 

 worked out. Sturtevant, A. H., Jour. Gen. n. 1912, p. 41.

 p. 331 and ibid. xni. (N. S.) 1912, p. 184 (especially 

 regarding dun colour). 



From these researches it seems to be established that 

 in the horse chestnut is the lowest colour in the series, and 

 that white is epistatic to all. As to the order of the other 

 factors there is not complete agreement. Sturtevant gives 

 reasons for the view that black stands next above chestnut, 

 and bay-or-brown taken as one indivisible type next above 

 black. Grey and roan come above these and below white. 

 Walther has much useful information as to the behaviour 

 of the peculiar piebald and spotted types.
