The numerous cases in which peculiarities belong-

 are of particular interest, as they illustrate the manner 

 in which resemblances are sometimes transmitted by 

 atavic descent. 



Mr. Talcott reports the following case. He says : 

 " I had a fine cow with nice bag and teats, which I 

 took to a bull in the neighborhood, and the produce 

 was a heifer-calf, which was raised because of the good 

 milking-qualities of her dam ; but when she became 

 a cow, instead of any of the good qualities of her dam 

 as was expected, her bag and teats were more in con- 

 trast (sic) with that of a sheep than of a good dairy- 

 cow. I then began to investigate the cause, and found 

 that the heifer was the counterpart of the dam of the 

 bull, she being an ordinary cow with a small bag and 

 still smaller teats, and from that time to this I have 

 found that too frequently that is the case, especially 

 if the bull was from such a stock or family of light 

 milkers that it was not desirable to perpetuate them. 

 I remember distinctly the first pure-bred Short-Horn 

 bull I ever had, that the bag of his dam was the largest 

 in the hind-quarters, consequently that she gave most 

 milk from the hind-teats, and that quality was trans- 

 mitted to the majority of his heifers when they came 

 to be cows, their bags tending largely in the hind- 

 quarters. And I think, from such observations, that
