 to be understood, because a prevailing vicious practice is in 

 vogue, under the pretence of exploring, by cutting away the 

 sole of every lame horse in search for matter, and, as is 

 supposed, to give it vent. Blood only, in the case, is found, 

 and with that the searcher is satisfied ; whilst mischief is 

 done, such as takes long to repair, even when the patient gets 

 under better care. The proper treatment for corns is a 

 rightly-applied system of shoeing for which, consult di- 

 rections on that subject.

 Union never takes place again, but every hour after the 

 lesion is formed confirms and augments the state of the 

 disorder until remedied ; inflammation of the skin is set up, 

 the part is painful, and the lips of the wound gape as 

 the tissues swell. The inner quarter is the most common 

 seat of sand-crack, though it happens to both quarters of 

 the same foot in some instances. This ordinary character 

 of sand-crack happens only to the fore feet. 



The causes of sand-crack are more varied than those 

 which produce the last disease considered corn, the 

 strong and good feet often becoming the seat of that lesion 

 and attendant complications. 



In this respect the causes of these lesions are common, in 

 so far that sand-crack, like corns, requires the baneful influ-
