throw oif the scaly covering which eventually forms the main part 

 of warts. We see many instances of warts on the human hands 

 and other parts of the body, and always find that the dry, horny 

 part grows from the skin somewhat thickened and increased in 

 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 at\y 

 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-vessels 

 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 horij 

 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
