DISEASES OF THE FEET. 



whereas, if no clasp or nails be applied, lameness manifests 

 itself, from the pinching of the sensitive laminae when the edges 

 of the crack approximate each other at the time the foot is on 

 the ground, as already explained. It is always necessary to see 

 that no dirt insinuates itself into the foot through the fissure, 

 and to keep it filled with some firmly adhesive material, such as 

 gutta-percha. If the growth of horn seem inactive, a slight 

 blister to the coronet will prove useful, by promoting a more 

 rapid secretion. At all times, and for sand-cracks in any part of 

 tlie foot, a bar shoe, if the frog is not diseased and unfit to bear 

 pressure, is useful. In this, as in all other diseases of the feet, 

 the sole is to remain unpared, and allowed to bear its due share 

 of the animal's weight. When the crack is at the quarter a 

 three-quartered bar shoe, to remove weight from it, is to be 

 recommended. 



KERATOMA. 



The two following woodcuts, fac-similes of specimens in my 

 possession, will illustrate tliis condition of the foot : —
