THE OX TRIBE. 



have made the following observation : " I need hardly 

 observe, that if a cow has twins, and they are both bull- 

 calves, they are in every respect perfect bulls ; or if they 

 are both cow-calves, they are perfect cows." What is 

 this but saying that a bull-calf is a bull-calf, and a cow- 

 calf is a cow-calf ? For a Free Martin, or hermaphrodite, 

 is not, in any case, either a bull or a cow. 



There does not appear to be anything known of the 

 peculiar circumstances under which, what is termed a 

 Free Martin is produced. 



The most general observation that can be made on the 

 subject appears to be, that cows sometimes produce calves, 

 which, by reason of their imperfectly developed generative 

 system, are incapable of procreating.
