=Warts.= The most common tumors of the eyelids in horses, cattle, and
dogs are warts. These are most simply disposed of by seizing them with
rat-tooth forceps and clipping them off with sharp scissors curved on
the flat. Any bleeding may be checked by a pencil of silver nitrate.
=Sarcoma=, =melanoma=, and =epithelioma= are common in solipeds,
especially in the gray and white. They usually form a cauliflower-like
mass red and angry and bleed easily. They may occupy any part of the
lid, the skin, the dark tarsal margin, the connective tissue or the
mucosa, and not unfrequently they involve the eyeball, and the
surrounding tissues, even the bones of the orbit.
_Treatment._ These may be excised like warts taking care to remove every
vestige of disease. In these cases I have usually found it necessary to
remove the entire bulb.
