254: THE NATURE AND TREATMENT OF 



matter ; and the sooner this is done the better, for it will re- 

 lieve the animal of much suffering and prevent ulceration of 

 'the jaw bone. Very little after treatment is recjuired. It is only 

 necessary to cleanse the part daily, and dress with tincture of 

 matico. 



EXOSTOSIS, OR DEPOSIT OF CALCAREOUS MATTER ON 

 THE SURFACE OF BONES. 



Exostosis signifies an unnatural growth of bone, or deposit of 

 calcareous matter on the surface of bones. Among horses this 

 disease occurs in the form of splent, spavin, and ringbone. It 

 is very seldom that cattle are treated for this affection ; for the 

 deformity is so slight, and the lameness so obscure, in conse- 

 quence of the slow motions of the animal, that very little no- 

 tice is taken of it. The proper mode of treatment is to apply, 

 daily, a small quantity of Iodide of Glycerine^ prepared as fol- 

 lows : — 



Iodine, 1 drachm. 



Glycerine, 1 ounce. 



Mix, apply by means of a small piece of sponge. This is 

 to be applied daily for a period of two weeks, after which use 

 acetic acid, one part ; water, six parts. With a portion of this, 

 sponge the enlargement until pain and lameness disappear. 



CARIES, OR ULCERATION OF BONES. 



The cut at page 245, will give the reader a better idea of the 

 appearance of ulcerated bones, than a description. It is a 

 very common disease among cattle, and is preceded by inflam- 

 mation and suppuration. It sometimes proceeds from a blow 

 received at the angle of the jaw ; generally, however, it is a 

 constitutional disease of a malignant character. 



Treatment. — In the first stages of this disease, the part 

 being hot, painful, and tender, I should foment with warm 

 vinegar, which will tend to hasten suppuration ; then having 

 ascertained that there is some pus or matter locally imprisoned, 

 the part must be freely punctured, the pus evacuated, and the 

 iftavity injected with pure pyroligneous acid.
