WARTS. 281 



Such an annoyance are warts to some horses, that hardly 

 any part of the body is free from them. They cannot be 

 harnessed, saddled, or bridled, for warts. The most common 

 situation for warts to grow upon is the head — particularly 

 the eyelids, about the muzzle and ears — the belly, the 

 sheath, the penis, the inner side of the thigh and arm : in 

 fact, they appear to select those places where the skin is 

 thin, and the hair comparatively scanty. Warts vary in — ' 



Magnitude, Aspect, and Structure. — Sometimes we 

 meet with them about the size of peas : in other cases, a 

 single wart has been known to grow to a size which impeded 

 the action of the limbs. In general, warts are enveloped in 

 cuticle, which is thin, smooth^ and hairless ; though, in time, 

 it often becomes callous, and assumes quite a horny texture. 

 In other cases, their surfaces are ulcerous, and even fungoid, 

 bleeding on the least irritation, and showing no disposition 

 to cicatrize. When cut into, they in general exhibit a 

 firm, fibro- cartilaginous texture, and seldom bleed from 

 their interior, or even exhibit any vascularity in it, though 

 hemorrhage is often considerable from their roots. Warts 

 are said to be produced by the cutis, whence they derive 

 their coverings ; some growing by pedicles, others possessing 

 broad roots : though there are warts encased in skin, out 

 of which they slip, when liberated by incision. It has 

 occurred to me, when the case appeared to be of this kind, 

 and I expected to give escape to one of these marble-like 

 structures, that the cyst has been filled with a soft matter — 

 in colour and consistence like cheese. At other times, the 

 soft substance is of a granular nature. C 27, had upon 

 the nose a wart, covered by smooth, tense, shining skin : this 

 I thought was encysted, and would prove firm and solid : 

 it was encysted y but of the granular kind. 



It appears to me that these soft warts never give rise 

 to ulceration of the skin, whereas the solid warts do. B 33, 

 had a wart of this description upon the chin. This appeared 

 to have a deeper origin. Sometimes we meet a wart of old 

 standing, bulky, and with the appearance of being callous ; 

 but which, when we come to handle it, proves to be in a
