case could be imagined. If one or more white 

 Shorthorn bulls were put to a herd of red North 

 Devon cows, their progeny would all be roans. 

 At the same time, they would be intermediate 

 between their parents in size, as well, perhaps, as in 

 some other things which we may neglect for the 

 present. If those roan crosses were bred together, 

 25 per cent, of their progeny would be white, 50 

 per cent, roan, and 25 per cent. red. At the 

 same time, 25 per cent, of the whole would be 

 Shorthorns in size, 25 per cent. Devons, and 50 

 per cent, intermediates. But, as the chances are 

 absolutely against both colour and size varying 

 together, there are reds, whites, and roans among 

 the cattle of Shorthorn size, and reds, whites, and 

 roans among those of Devon size. The white- 

 coloured cattle of Devon size are white Devons, 

 from which any number of white Devons might be 

 produced, and by the use of such cattle the whole 

 red Devon breed could be made white in not so 

 very many generations. 



There are, however, hybrids which are not 

 obvious intermediates, but which masquerade in 

 the guise of one of their parents. The progeny 

 of black and red cattle are black, yet they are 

 hybrids nevertheless. When these masquerading 

 hybrids are bred together, a quarter of their 

 progeny are red, like one of their grandparents, 

 and three quarters are black, like the other, but 

 of the black ones only a third are genuinely black ;
