BASTARD OF THE SELVAGE COW 



The Bastards of this Class, (see Plate IX. Fig. 3) whatever may be their size 

 and the Order to which they belong, are to be known by two patches of ascend

 an inch and a half wide. The smaller they are, and the finer the hair within 

 them, the less rapid is the loss of milk which they always indicate. When they 

 consist of coarse hair, and terminate in a point at each end, they indicate that the 

 milk is poor and serous.
