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, ate to be known by two patches of ascend- 

 ing hair, (F F) on the right and left of the vulva, distant from it an inch and a 

 quarter to an inch and a half They are from four to five inches long by about 

 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. 



CLASS III.

I have given this name to the Cows of ray Third Class, because their escutch- 

 eon, which is lozenge-shaped, is bounded above by two curved lines ; which, 

 commencing to the right and left on the thighs, run up toward the vulva, and 

 meet at a point below it. (See Plate III.) 



This Class is a very numerous one ; and, in regard to the yield of milk, approx- 

 imates to the First Class. Cows belonging to it, and to every one of its Orders,
