tendon when the surface of the former has been the seat of dis- 

 ease. In the last-named case, the recovery is Hkely to be the 

 more permanent, while many cases of apparent recoveiy, in the 

 early stages, are followed by relapse. The frog seton is intro- 

 duced at the hollow of the heel and brought out at the body of 

 the frog, but as there is much danger of wounding the tendon 

 or bursa in incompetent hands, it can only be safely undertaken 

 by the veterinary anatomist. 



All other methods failing, resort is often had to cutting the 

 nerves passing to the foot, so as to remove all sensibility. This 

 should never be done unless the feet can be carefully picked 

 out and sponged every time the animal returns from work, and 

 kept covered with thick wet swabs all the time he stands in the 

 stable. Neglect is sure to be followed by rapidly advancing 

 disease in the bone, extension of inflammation to the structures 

 around, abundant exudation, and destruction of bones and 

 joints. Even with the best of care this will occur in the ad- 

 vanced stages of the disease, unless indeed the bone and 

 tendon grow together. For description oi neurotomy see larger 

 work. 



SIDE BONES. 



These consist in extensive ossification, from the heels of the 

 coffin-bone into the lateral cartilages. Their great cause is im- 

 proper shoeing ; cutting away of the bars or sole, so that the 

 wall turns inward and bruises the sole ; pressure of the shoe on 

 the sole, whether from misfitting or from being left too long on; 

 uneven bearing of the shoe, throwing too much strain on one 

 part; pricking or pinching with nails driven too near the quick: 

 the pressure of the dry hard horn after undue paring or rasping, 

 and the continuous irritation which attends the partial separa- 

 tion of sole and wall. They are especially common in heavy 

 horses with upright pasterns and the toe shortened relatively to
