CANKER. 287 



with the moisture which exudes, it becomes weaker, 

 and is speedily neutralized. Except it is used in out- 

 rageous quantities, it cannot deeply corrode the foot. 



This being done, dry soft tow must be spread over 

 the whole of the exposed surface, and made firmly 

 and equally to press upon it ; and the horse must be 

 put into a thoroughly dry box, from which the urine 

 will immediately run off, and where no kind of 

 moisture can reach the diseased part. A cankered 

 foot, however, must not be dressed too frequently. 

 The two or three first dressings may be given on suc- 

 ceeding days ; but, when the fungus has been in some 

 degree subdued, the bandages should only be removed 

 every fourth day, or even once a week. Every time 

 that the foot is exposed it should be carefully ex- 

 amined, in order to see that there is no portion of 

 unhealthy horn ; for if there is, it must be immediately 

 removed. The appearance of the exposed surface 

 must also be inspected with great attention. Fresh 

 fungus will require a fresh application of the butyr, 

 or possibly of the knife. Every little pellicle of 

 skinny matter or soft and porous horn must also be 

 pared away. The healthy horn which has been secreted 

 must be lightly run over with the knife, and then the 

 butyr of antimony once more applied to the whole of 

 the surface. The quantity used on the different por- 

 tions of it should vary with the progress towards a cure. 

 After this the foot must be bound up as before. 



A few days having passed — if the sprouting of the 

 fungus has been quite checked, but yet the horn does 

 not grow so healthily as could be wished, the butyr may 

 be omitted ; a pledget of tow should then be dipped
