320 COMPENDIUM OF THE VETERINARY ART 



a horse's foot is wounded by the farrier in 

 shoeing, be is said to be pricked ; the nail, 

 instead of being driven into the horny insen- 

 sible part only, is either forced into the liv- 

 ing parts, or so near to them as by it's pres-

 cause him to go lame; inflammation gradually 

 takes place in consequence, and at length 

 matter forms, which, if not allowed to escape 

 by removing the shoe and cutting away the 

 horn with a small dravving knife, spreads 

 under the hoof, and after some days breaks 

 out at the coronet. (See Anatomy of the Foot.) 

 In this case the mischief is not alw ays disco- 

 vered immediately after shoeing. The pressure 

 upon the sensible parts is sometimes too 

 inconsiderable at first to occasion lameness; 

 so that when the horse is observed to go lame, 

 the farrier oronounces it to be in the shoulder, 

 and the poor animal is tormented by the 

 strong oils or even blisters applied to that 

 part, while he is suffering from another cause. 

 It is in this way that the disease is sometimes 

 allowed to run such lengths as we have 

 described. When the nail is so driven as to 

 wound the sensible parts at once, the horse 

 o-oes lame immediately after; and the cause
