the surface of the bone has not been diseased, or it may 

 be a removal of lameness ia connection with a union of 

 the bone and tendon when the surface of the former has 

 been the seat of disease. In the last named case, the 

 recovery is likely to be the more permanent, while many 

 cases of apparent recovery, in the early stages, are followed 

 by relapse. The frog seton is introduced at the hoUow 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 faiUng, resort is often had to cutting 

 the nerves passing to the foot, so as to remove all sensi- 

 biUty. 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 advanciug disease in the bone, exten- 

 sion 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 advanced stages 

 of the disease, unless indeed the bone and tendon grow 

 together. For description of 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 improper shoeing ; cutting away of the bars or 

 sole, so that the waU 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 

 di-y hard horn after undue paring or rasping, and the con- 

 tinuous irritation which attends the partial separation of 

 sole and wall. They are especially common in heavy 

 horses with uprigLt pasterns and the toe shortened rein-
