756 DISEASES AND THEIR TREATMENT. 



a common nicking-knife, to the top, and cut down to the bone. 

 The part may now be treated as for simple inflammation; after- 

 ward, simply by cooling applications. The usual treatment is, 

 after the acute stage has passed oft', to clip the hair and blister 

 once or twice. Or, a more eflfectual way would be by firing, the 

 best way of doing which is by the pyro-puncture process ; but this 

 is seldom necessary. 



I give several excellent remedies for splints and ordinary en- 

 largements, either of which may be used ; also a number under 

 the head of Special Remedies, given near the close of this book, all 

 of which are very good. The following is also used with much 

 success: — 



1 ounce oil of origanum. 

 1 ounce oil of turpentine. 

 ^ ounce of alcohol.

Spavin. 



There is so much misconception among people generally about 

 the nature of spavin and its cure, that I will include such illustra- 

 tions as will show clearly the character and location of the disease. 

 I first give various views of the hock, with an explanation of the 

 diflerent parts. Also views of specimens of a bad condition of 

 spavin; first, a union of all the bones of the hock without 

 any enlargement; next, the same condition with a large, bony 

 deposit, the result of long-continued inflammation of the parts. 

 This enlargement is what is called a spavin. Many pretend 

 to be able to cure spavin by a medicine that will take off" the 

 bunch, claiming that it is simply a form of detached growth, and by 

 removing this a complete cure will be effected. The fallacy of this 

 pretension would be better understood could the specimens from 

 which the illustrations are taken be ex^amined. 



The remedies generally used are nitrate of silver, corrosive sub- 

 limate, arsenic, muriatic, sulphuric, and nitric acids, or their com- 

 binations with other medicines of less severe character. These 

 medicines aj^plied to the surface deaden or destroy the skin and 

 sub-tissues of the part, which, in the course of a week or two, 

 sloughs off", leaving a bad sore. The operator exhibits this sloughed
