    denuded spot, especially where the growth was attached to the cornea, and applied an antiseptic dressing. After forty- eight hours the bandage was removed. The eye showed very little reaction, the edges of the conjunctiva were united, the haziness of the cornea, excepting ij m.m. at the inner edge, had disappeared, and at the spot where the tumor had its origin was a slight vascular depression. In twelve days after the operation the patient was dismissed, with the ap- pearance of the eye normal as seen in the accompanying pho- tograph, and with vision almost normal. April 16, 1892, the patient writes that eye is as well as it ever was and growth shows no signs of reappearing. The tumor removed is of medium consistency, with a glis- tening appearance and of the following dimensions: horizon- tal diameter 25 m.m., vertical 15 m.m., perpendicular 10 m.m., base 4 by 5 m.m. Immediately after the operation, the tumor was placed in Miiller's fluid and Dr. Tower, who made the microscopical examination, gave the following re- port: Fig. I shows in section the tumor with hairs and small masses of sebum attached to the interior; when cut open a fatty fluid and some pultaceous material es- caped from the cavity leaving in sight the hairs and sebum. Upon section and microscopical examina- tion as in Fig. 11 there are sebaceous and sudoriferous glands, hairs, etc. The dermal Transverse Section, layers are very distinct and separate; though the superficial horny scales of the corium are more cellular in construction than is found upon section of a piece of cutis from the body in an unexposed situation. In classification this tumor would occupy a place in congenital cysts and from its situation in the body be an epiblastic inclusion, as the conjunctiva receives its origin in the mesoblast, i. e., its con- nective tissue portion.
