to be scraped to expose a living surface. But in wounds of the 

 tendon or joint the foot must be wrapped in cloths, the heels 

 raised if standing, and a constant stream of cold water kept up 

 on the part, by having a caoutchouc tube attached to the limb 

 and foot and acting like a syphon to bring the water from a 

 bucket at a higher level. This may require to be kept up day 

 and night for several days. The subsequent treatment is like 

 that for pedal sesamoiditis. 



DISTORTIONS OF THE COFFIN-BONE. 



Under this head may be named a great variety of deformities, 

 the result of disease. Thus in long continued inflammation of 

 the laminae the fibrous net-work in front of the coffin-bone is 

 partly ossified, giving this part a convex aspect from above 

 downward. Continued irritation of the sole will equally de- 

 velop a bony enlargement which is associated with a circum- 

 scribed convexity and tenderness of the sole. The pressure of 

 a homy tumour, whether on the laminae, the quarter, or else- 

 where, corresponding to and pressing on the bone, will cause 

 absorption and depression of the bone to an equal extent. The 

 pressure on the anterior border of the coffin-bone, when sepa- 

 rated from the hoof-wall and resting upon the sole, leads to 

 extensive absorption and rounding of this part with a bony de- 

 posit above, on its front. Persistent irritation along the lateral 

 borders of the foot from binding with nails, or the separation of 

 the wall and sole, with or without the presence of gritty matters 

 in the groove, causes absorption and rounding of the sharp 

 lateral margins of the coffin-bone. But the heels of the coflUn- 

 bone are the parts which above all suffer in this way. Bruises 

 from setting in of the shoe, from gritty matter or hard clay, 

 especially if a furrow has been formed between wall and sole, 

 from curving forward and inward of the heels when the support- 

 ing sole has been pared out /// search of corns or to prevent their 

 Jorination ; j^essure from curving in of the wall, which has been
