strument shown in fig. 312 may be used. The margins of 

 the opening, so far as they are formed by the sole, should be 

 thinned until they yield to the pressure of the finger. If pus 

 be discovered the parts are next flooded with warm 5 per cent, 

 carbolic, creosote, or creolin solution, and covered with carbolic, 

 sublimate, iodoform, or salicylic wool. There is some advantage 

 in afterwards painting the parts with a resinous tincture, like 

 tincture of myrrh or the compound tincture of myrrh and aloes. 

 The dressing is held in position by broad strips of gauze and a

shoe with leather sole applied. A better way to fix dressings 

 in position is by thrusting two thin strips of wood or hoop iron 

 cross-wise between the dressing and shoe. 



If no pus be found, cold poultices or baths may be continued. 



The colour of the pus is of importance. A grey fluid dis- 

 charge is a result of superficial inflammation of the corium; a 

 condition which readily yields to treatment. The production of 

 yellowish thick pus, however, even in very small quantities, 

 points to inflammation of the deeper lying layers of the corium 

 and to a more obstinate condition. Under such circumstances 

 the advice of a veterinary surgeon should be sought.
