INHERITANCE IN RAGE HORSES 89 



no other colour than the dominant greyuess, so that 

 whatever kind of mating they may be a partner in, 

 their offspring, without exception, will be grey. 

 In other words, are there grey horses whose sex- 

 cells all carry the factors that produce greyness in 

 the coat ? Greyness beiug, as we have reason to 

 believe, a dominant character over black, chestnut, 

 brown, and bay, it follows that in any mating of 

 grey horses, with those of either of these other 

 colours, the sex-cells of the pure grey parent, being 

 carriers of grey alone, must necessarily introduce 

 the dominant colour grey into one side of all such 

 matings, and grey will result. I think I can pro- 

 duce such a case from one of the most scientifically 

 kept Studs in the world, namely, that of Celle 

 belonging to the Prussian Government. In this 

 Stud every detail is accurately recorded by properly 

 trained experts. 



The case I have in view is that of a ten year 

 old white Arabian stallion, the *' Celle Amurath," 

 This horse, in England, would be called grey, but 

 white in Germany. Its coat is white, but its eyes, 

 mane, tail, and feet are black. 



" Celle Amurath " has covered about six 

 hundred mares of all colours, and his numerous 

 offspring, without exception, have been greys and 

 whites. There can therefore, I think, be little 

 doubt that he is a pure white (grey) and is DD 

 for whiteness (greyness), carrying only this colour 

 character. 



When we examine his parentage and more 

 remote ancestry, our conclusion as to his Mendelian
