264: PRINCIPLES OF STOCK-BREEDING. 



ported, I think, having very straight hair. Three 

 years ago this bitch was bred by him to another shep- 

 herd of a different species a large, shaggy-haired 

 breed. I saw her last litter of pups, after she had 

 been confined during the whole period of heat with a 

 dog of her own species, and, without knowing the 

 fact of her having been so bred, remarked upon the 

 singular difference in size, shape, and appearance, of 

 two of the litter from the remainder they being half 

 as large again, and seemingly of another breed entire- 

 ly from her or the father. I was told then of the 

 above-mentioned facts, which explained conclusively 

 the result, and I think logically and truly." l 



Prof. Agassiz states that he had " experimented 

 with a Newfoundland bitch, by coupling her with a 

 water-dog, and the progeny were partly water-dog, 

 partly Newfoundland, and the remainder a mixture 

 of both. Future connections of the same bitch with 

 a greyhound produced a similar litter, with hardly a 

 trace of the greyhound. He had bred rabbits with 

 the laws established by this experiment, and had at 

 last so impregnated a white rabbit with the gray rab- 

 bit that connection of this white rabbit with a black 

 male invariably produced gray." a 



A celebrated breeder of Short-Horns, of my ac- 

 quaintance, bred the females of a light-colored family 

 to a red bull, and afterward to a bull of their own 

 family ; and he succeeded, in this manner, in produc- 

 ing the desired shades of color in the offspring of the 

 light-colored females.
