INFLUENCE OF A PREVIOUS IMPREGNATION. 263 



B. A. Alexander imported. (York was got by the 

 famous Spring.) At the same time I bought a bitch, 

 Fannie (Scotch collie), first produce of the imported 

 pair owned by H. A. Alexander. Fannie and York 

 were the only dogs on the farm, and are both still

 dogs, yet every litter of pups has from one to two

 until her death, with every litter, to bear one or two 

 yellow pups. Some of the pups I have seen myself, 

 and he yet owns one in Chattanooga."

bluish-tinted shepherd, of a peculiar breed, and im-
