FOOT DISEASES. 99 



make the hard and inelastic foot one that will expand at 

 its heels every time the weight of the animal puts his foot 

 to the ground. 



One-sided nailing is an excellent preventative as well as 

 an assistant in the cure of contracted feet. What is meant 

 by one-sided nailing is, that nails are to be confined to the 

 outside toe of the foot, so as to allow free expansion for the 

 heels. This cannot be done with the shoe being nailed on 

 by nails placed at each side. To illustrate this point, place 

 a small horse-shoe flat in the palm of the hand with the 

 fingers close to one another ; then tie, with a piece of cord, 

 the little finger to one side of the shoe, and the thumb to 

 the other side; then you will realize to what extent you 

 can expand the fingers so secured. So it is just with the 

 foot of a horse with the shoe nailed on at each side. Re- 

 move the cord from one finger, and the whole hand is free 

 to expand. So likewise the foot of the horse by one-sided 

 nailing. 



(3.) CoENS. — This is a red spot on the inner portion of 

 the heel of the foot, causing lameness, and consists of a 

 bruise from the shoe pressing upon the part, the shoes 

 having shifted from their proper position, or never having 

 been placed there. In general, the production of corns 

 may be laid to the charge of the horse-shoer, and sometimes 

 to the owner allowing the horse to go too long before the 

 , shoes are removed, or before the foot has grown from the 

 shoes. Corn is an analogical term, although bearing no 

 resemblance to that well-known afiection of the feet of man. 



Treatment. Remove the corns by cutting them out ; then 

 apply a few drops of commercial sulphuric acid to the part. 

 Shoe the horse sufficiently often to insure even bearing to 

 the shoe upon the wall only of the foot.
