522 SANDOEACK. 



11^ — After cutting away as mucTi horn as may be deemed 

 necessary (the more the better), and before the warm cement 

 is applied, the animal should have a bar-shoe secured to the 

 foot. 



III. — In binding the foot, avoid passing the wire imme- 

 diately over the exposed villi, unless these structures are well 

 covered with a small pad of fine tow or cotton wool, previously 

 dipped into the warm cement. 



The advantages derived from treating Sandcrack as directed 

 above are these : — it cures the malady thoroughly ; while the 

 new horn, if the animal be allowed to rest, will be so thick and 

 abundant that it will never again crack in the same locality — 

 an advantage which is not obtained by any other known mode. 



The crust of the foot is secreted at the rate of one inch in 

 three months ; and one inch of new horn should be in existence 

 before the animal is again put to work, otherwise there is con- 

 siderable risk of the new horn being split, and the animal again 

 becoming lame. 



COENS. 



" This is a very common and a very troublesome disorder ; 

 it is frequently occasioned by the smith, or in consequence of 

 bad shoeing. Corns are the most common to flat feet, and 

 feet with weak, low heels. They are occasioned by the pres- 

 sure of the heel of the shoe, either by its bearing immediately 

 on the sole where it is too thin to bear the pressure, or by the 

 shoe forcing the heel of the crust inwards. In this way the 

 sensible sole is frequently bruised, the small blood-vessels rup- 

 tured, and the effused blood penetrates the pores of the horny 

 sole, thereby causing the dark red appearance observable on 

 paring out the heels.* (See// Mg. 11, page 85.)
