THE DISEASES OF THE HORSE. 



HORN TUMOR (KERATOMA), 



Is caused either by pressure of the toe clip of the shoe, 

 the clip having been hammered too tightly by the smith, 

 or by the animal striking the toe against the ground. 

 These tumors are analogous to corns in the human feet, 

 and consist of an increased secretion of horn. They are 

 peculiar to the hind feet, but they are not uncommon in 

 the fore.

Remedy. — First try properly adjusted shoes. If this 

 fails, isolate the diseased part by grooving, as in the pro- 

 cess of ' stripping/ but leave the horn unstripped. Strip- 

 ping consists in the removal of the whole of the crust 

 immediately over the diseased part, by cutting through it 

 on either side from top to bottom, detaching it from the 

 sole, and tearing it off, leaving the sensitive parts ex- 

 posed. This cruel treatment should never be resorted to
