THE COATS. 799 



Large white -foot, or half-stocking, when it reaches the middle 

 of the canon. 



Stocking, when it extends to the knee or the hock. 



High stocking, when it reaches still higher and extends upon the 

 forearm and the leg. 



Finally, very high stocking, when it reaches the vicinity_of the 

 body. 



c. In relation to its composition, it is similar to the markings of 

 the head : 



Bordered, speckled, ermined, trout-spotted, mixed, mar- 

 bled, etc. 



We should mention the white-feet of gray horses only in cases 

 where these markings are perfectly apparent. 



[In a certificate of soundness, it suffices to specify the name of the 

 region which is white, it being understood that the white coloration 

 exists. As to the head, it is only necessary to mention the character 

 of the marking without stating that it is on the head. 



Examples : light bay, star, off hind pastern ; burnt sorrel, blaze, 

 three half-stockings near hindj] 



Zebra Marks. The zebra marks are black or blackish sinuous 

 lines directed transversely upon the regions of the forearm, the leg, the 

 knee, the hock, and the canon, which recall somewhat the disposition 

 of those seen upon the zebra. They are observed more frequently 

 upon the Isabella, the mouse, the sorrel, and the fawn bay, 



Arborizations. The arborizations are peculiarities analogous to 

 the preceding, but differ from the latter in that they are formed of 

 white hairs. They are located upon the external face of the forearm, 

 the leg, and the back of the ears, in horses exclusively gray. Our 

 observations, extending over a long period, have taught us that these 

 markings follow very accurately the direction of the corresponding 

 subcutaneous arterial branches (anterior radial, anterior tibial, and 

 posterior auricular arteries). 



Color of the Horn. The color of the skin of the coronary 

 band determines that of the horn of the hoof in the parts situated 

 below. It is frequently modified by white markings in the region of 

 the foot, and may, in fact, be white, black, or mixed. 



3. Causes of the Modifications of the Coats. 



In general, coats of the same color and even the same shade have 

 not, at all times, identical characters. This is due to diverse influ-
