smooth, and hairless skin, but which in time becomes 

 callous and horny. Others are ulcerous and even fungoid, 

 bleeding on the least irritation and showing no disposition 

 to heal. Internally they exhibit a firm, fibro-cartilaginous 

 texture, little or no vascularity, and seldom bleed except 

 from their roots.

Remedy. — Remove by excision, torsion, or ligature. 

 To prevent return, cauterize the site of those about the 

 penis. Chromic acid, silver nitrate, and glacial acetic 

 acid destroy warts. The soft variety gradually removed 

 by daily moistening with commercial acetic acid. 



Where the wart grows from a slender pedicle, a double, 

 well waxed, silk ligature, drawn tightly, is the best means 

 of removal. Should the ligature cut the wart, apply the 

 budding iron to its surface. Encysted warts require cru- 

 cial incisions and pressing only. If a wart has a broad 

 base, caustic is more effectual than ligature. Sprinkle 

 the wart with arsenic. It will fall off in about two weeks. 

 Sulphur made into a paste, with sulphuric acid, will an- 

 swer the same purpose. Chloride of zinc, powdered, and 

 rubbed with a simple ointment, is good. Warts of the 

 eyelids should be removed with the knife.
