throw off the scaly covering which eventually forms the main part 
of warts. We see many instances of warts on the human handa 
and other parts of the body, and always find that the dry, horny 
part grows from the skin somewhat thickened and increased iu 
vascularity. So great, indeed, is the quantity of blood which 
some warts receive, that they bleed much more profusely than 
other portions of skin when wounded. 
The other kind of wart to which we alluded does not cause any 
external roughness or scaly appearance. It is formed within the 
outer skin, and commonly appears as a circumscribed round tu- 
mor. On being examined by the hand, it is felt to be contained 
in a sack or pouch, within which it is easily moveable. It is 
almost insensible, and consists of a quantity of white fibrous and 
sometimes grisly substance, which does not possess blood-vessela 
in its interior, We often meet with this kind of encysted wart 
near the outer organs of generation in the horse or mare. The 
horny wart which we first noticed is common in horses, cattle, 
and dogs. The encysted wart is comparatively rare in cattle; it 
is more common in dogs, but is most frequently found in horses. 
Treatment.—In treating warts with a view to remove them, and 
prevent their reproduction, it becomes necessary to destroy, in a 
measure, the surface from which they sprout. When an angle- 
berry has.a “neck,” this should be cut off flat and close with the 
skin, and the raw surface thus made should be touched occasion- 
ally and freely with caustic or a heated iron. If the neck be so 
large as to endanger much bleeding if divided at once, a ligature 
of thin, strong string may be tied round it very tightly, in order 
to cut off its supply of blood. The ligature should be applied 
frequently—daily, if convenient. Where a large surface is cov- 
ered by warts which do not possess any definite necks, their horny 
parts should be cropped or cut closely down to the true skin, with 
scissors or other convenient instrument, and the surface thus ex- 
posed should then be touched with a hot iron, or rubbed with 
caustic potass. Such application is to be continued till the horn 
ceases to grow. Encysted warts are removed by cutting the skin 
of the sack and squeezing them out. The exposed cavity should 
be dressed daily with digestive ointment.
