 sore and travel-short a day after be bas bad any work, 

 especially over bard and rugged streets. 



PUMICED FOOT is considered uusoundness when the 

 union between the horny and sensible laminae, or little 

 plates of the foot, is weakened, and the coffin-bone is let 

 down and presses upon the sole ; " when the sole yields to 

 this unnatural weight, and becomes rounded, and is brought 

 in contact with the ground, and is bruised and injured, 

 that horse must be unsound, and unsound forever, because 

 there are no means by which we can raise the coffin-bone 

 again into its place," says Mr. Youatt. 



PAEALYSIS is to be considered as unsoundness, as it is a 

 disorganization of some part of the nervous system, and 

 must be considered as such ; although great difficulty may 

 arise to trace it to its seat, yet sufficient is known of the 

 disease to designate it as an unsoundness. Various causes 

 might be the means of bringing on this trouble, but no 

 matter the cause, the result is what we are to deal with ; 

 an animal having been once affected, is very much predis- 

 posed to a future attack, besides the actual weakness that 

 must remain for some time at the spot where the disease 

 was seated ; and the only manner in which a horse that 

 has had paralysis could be warranted, is, after the animal

QUITTOR is to be considered as unsouudness, (no matter 

 jf" the abscess ceases to discharge its humor and the wound
