of bone can be determined by the use of the probe 5 the bone feels rough 

 and gritt^'. Furthermore, there is no disposition upon the part of the 

 wound to heal. 



Besides the compilcatious above mentioned others, equally as serious, 

 may be met with. The tendons may soften and rupture, the hoof may 

 slough off, quittors develop, or sidebones and ringbones grow. Finally 

 laminitis of the opposite foot may happen if the imtient persists in 

 standing most of the time, or lockjaw may cause early death. 



Treatment. — In all cases of punctured wound of the foot the horn 

 around the seat of injury should be thinned down, a free opening made 

 for the escape of the products of suppuration, and the foot placed in a 

 poultice. If the injury is not serious recovery takes place in a few days' 

 time. Where the wound is deeper it is better to put the foot in a cold 

 bath or under a stream of cold water, as advised in the treatment for 

 quittor. 



If the bone is injured cold baths, containing about 2 ounces each of 

 sulphate of copper and sulphate of iron, may be used until the dead 

 bone is well softened, when it should be removed by an operation. The 

 animal must be ca«t for this operation, the sole pared away until the 

 diseased bone is exposed, when all the dead particles are to be removed 

 with a drawing-knife and the wound dressed with a 5 i^er cent, solution 

 of carbolic acid, oakum balls, and a roller bandage. 



Wounds of the bone which are made by a blunt-pointed instrument, 

 like the square-pointed cut nail, in which a portion of the surface is 

 driven into the deeper parts of the bone, always progress slowly, and 

 should be operated upon as soon as the conditions are favorable. Even 

 wounds of the navicular bone, accompanied b}^ caries, may be operated 

 on and the life of the patient saved ; but the most skillful surgery is 

 required in these cases and only the experienced operator should 

 undertake their treatment. 



If there is an escape of pure synovial fluid from a wound of the sole, 

 without injury to the bone, a small pencil of corrosive sublimate should 

 be introduced to the bottom of the wound and the foot dressed as 

 directed above. 



The ether complications are to be treated as directed under their 

 proper headings. 



After healing of the wounds has been effected, lameness, with more 

 or less swelling of the coronary region, may remain. In these cases the 

 coronet should be blistered, or even fired with the actual cautery, and 

 the patient turned to pasture. If the lameness still persists, and is not 

 due to a stiff joint, unnerving may be resorted to, and in many cases 

 with very good results. If the joint is anchylosed of course no treat- 

 ment can relieve it, and the patient must either be put to very slow 

 work or kept for breeding purposes only. 



" Prick in shoeing " is an injury which should be considered under 

 the head of punctured wounds of the foot. The nails by which the
