Gestation of Cows, 



which have gone each period ; the third and fourth columns show 

 whether the produce was a cow-calf or a bull-calf; the fifth, if it 

 was twin cow-calves ; the sixth, if it was twin bull-calves ; and the 

 seventh, if it was twins of different sexes. For instance, if 279 

 is taken, it will appear that 32 cows went 279 days; that 16 of 

 tliein produced cow-calves, 11 of them produced bull-calves, 3 of 

 them produced twin cow-calves, none of them produced twin bull- 

 calves, and 2 of them produced twins of different sexes.
