AND MALFORMATIONS OF THE FEET. 63 



When these measures are promptly and efficiently 

 taken, injuries of the sensitive sole seldom prove 

 either serious or tedious. In a few days the horse 

 in most cases is again sound. 



The sole, however, having heen freely removed, 

 the horse is not fit for work, until nature has re- 

 supplied a sufficient quantity of insensitive sole for 

 the protection of the foot, or until an artificial 

 covering, such as leather, is provided. 



Leather, though we have objected to its use as a 

 substitute for a sole unnecessarily removed by 

 paring, is useful in the above cases, because it 

 affords the means of working the horse, as soon 

 as the inflammation caused by the injury has 

 subsided. 



Punctures of the frog are similar in nature, and Punctures

require similar treatment to those of the sole. 

 When taken in time they are not serious, and yield 

 to treatment even more readily than injuries of the 

 sensitive sole, inasmuch as the insensitive frog is 

 more permeable than the insensitive sole. 



If neglected, how&ver, they are apt to lead to 

 extensive disease of the frog, and canker may be 

 the result. In some few cases the inflammation 

 caused by the puncture may involve the neighbour- 

 ing coffin joint, and a serious and tedious case may 

 ensue. In still rarer instances it has happened 

 that a nail has penetrated through into the joint, 

 and fatal consequences have sometimes followed.
