CASE OF OSTEOMA OF THE CONJUNCTIVA. I (With Woodcut.)
BY EDWARD G. LORING, M.D., NEW YORK.
THE patient was a healthy and well-developed child of eight months. Just after its birth, a small fold of "skin," as the mother said, was noticed in the upper and outer angle of the eye. This fold began to be more and imiore apparent until the child was five months old, when it attained its present position and size, which have not changed during the last three months. T he eye has never been at all red except to a trifling degree, and then only at times over the fleshy protuberance. Nor has there been any pain connected with it. The protuberance presented the appearance of a small oval cystic growth, midway between the outer angle of the eye and the edge of the cornea, and was in about the horizontal meridian. It was not until the forceps touched the mass after opening into the fold that its bony or cretaceous character was suspected. It was firmly attached to the conjunctiva above and at the sides, though it did not appear to be attached at all to the globe. The operation healed kindly, there only renmaining, at the end of the fourth week, when the child was last seen, a slight injection along the wound. The other eye was perfectly normal. The child has a slight nmevoid-looking spot on each upper lid. The weight of the mass was 45 milligrammes; length, 8 mm.; width, 5.5 mmi.; height, 2.5 mm. It was oval in shape, with the long diameter in the horizontal nmeridian of the eye. It was convex above and concave below where it rested upon the sclera. The specimen was given to Dr. W. H. Welch, and his report is as follows: The bony growth is enveloped in a thin fibrous capsule. The growth is found to consist of true bone. Thin slices removed with the scalpel show perfectly formed lacunae and canaliculi No large medullary spaces are found, but there are Haversian canals, around which the bone corpuscles are arranged in lamellar systems,

as will be seen from the drawing by Dr. Eno. The addition of acid to a fragment of the specinmen causes an evolution of abundant bubbles of gas, leaving behind an organic residue.
Dr. Welch reports that only two other cases which had been reported are known to him. These are found in Graefe and Saemisch's " Handbuch d. gesammt. Augenheilkunde," Bd. IV., Th. 2, p. I5I, i876. Hie finds no reference to any cases since then in Virchow and Hirsch's "Jahresbericht."
