    red, flesh-colored excrescences, being met with either singly, or in little clusters. They may occur on the palpebral or ocular conjunc- tiva, and also on the semi-lunar fold, and bear a strong resemblance to the warts upon the prepuce. They are generally accompanied [Fig. 31. Fig. 32.] by a certain degree of conjunctivitis, and a thin muco-purulent discharge. They should be at once snipped off with scissors before they attain any size, or have time to spread, and if necessary, the cut portion should be lightly touched with nitrate of silver. Cysts of the conjunctiva may be readily distinguished by their circumscribed round form, and their pink, translucent appearance, the transparency of their contents being easily recognized with the oblique illumination. They may occur in different portions of the conjunctiva, and vary in size from a small pea to that of a hazel- nut, or they may even exceed this. If they extend into the orbit, and attain a considerable size, they cause more or less protrusion of the eyeball. The walls of the smaller cysts are generally very thin, and only so slightly connected with the conjunctiva that they may be very readily removed. Cysticerci have been found several times beneath the ocular con- junctiva, and in one instance (Sichel) beneath the palpebral. There is seen at some part of the ocular conjunctiva, near the angle of the eye, a transparent, cyst-like elevation, which is round, sharply defined, and somewhat movable, and varies in size from a pea to a small bean. The conjunctiva over the cyst, and in its vicinity, is somewhat hyperaemic, but if it is sufficiently thin and transpa- rent, we may be able to distinguish at the outer wall of the cyst a peculiar yellow or grayish-white spot, which is the head and neck of the entozoon, and Sichel1 states that this appearance is quite characteristic. CANCEROUS TUMORS are sometimes met with as primary affections, but far more frequently as secondary diseases, after cancer of the lids or of the eyeball. Iconograpliie Ophthalmologique, p. 702.
