3IO CLINICAL VETERINARY MEDICINE AND SURGERY. 



The patient was first brought for examination in June, and was 

 then regarded as suffering from granular conjunctivitis. The vegeta- 

 tions were removed with scissors, and the parts curetted. At this time 

 the eye was still intact. A i per 2000 sublimate solution was prescribed 

 as a collyrium. 



The parts did not heal. Further vegetations developed and rapidly 

 increased in size. 



When the horse was left in hospital a reddish, flattened, trans- 

 versely elongated tumour, somewhat resembling a strawberry, projected 

 from between the eyelids. The upper lid remained soft and moveable ; 

 the lower, from which the tumour sprang, was everted. The globe of 

 the eye was partly covered by the new growth, and to some extent 

 pushed back into its cavity. The right side of the face was denuded 

 of hair, and soiled by a purulent discharge. 



Operation. — Once the animal was cast it was discovered that the 

 tumour had invaded the globe of the eye. The cornea was opaque 

 and perforated at two points. It therefore became necessary to remove 

 the whole of the eye and a part of the lower eyelid, preserving as far 

 as possible the skin covering the latter. 



The orbital cavity was cleared out and filled with gauze, and the 

 eyelids were brought together with three sutures. This dressing was 

 removed next day, and treatment was afterwards confined to antiseptic 

 injections. 



The tumour was the size of a walnut, elongated in its transverse 

 diameter, slightly flattened, rounded on the surface, and of firm con- 

 sistence. The surface of sections appeared dry, but pressure caused 

 filaments or little grains to exude, which were exclusively formed of 

 epithelial cells. 



The histological appearance of the tumour showed it to be an 

 epithelioma of the pavement epithelium type. It was formed of a 

 connective-tissue stroma and of epithelial cells disposed in lobules, 

 which were massed closely together or united by tracts of the same 

 character. 



The animal left on the ist March, but was brought back two months 

 later for the application of an artificial eye of hardened india rubber. 

 The tumour did not return. 



MALIGNANT CARCINOMATOUS INTRA-ORBITAL GROWTH WITH 

 DESTRUCTION OF THE EYE IN A COW. 



II. A well-bred shorthorn cow; first seen March 20th, 1893. 



History. — Two years before the animal had suffered from '' chaff in 

 the eye," followed by a cold. Nothing was done. 



State on Examination. — The right eye was totally destroyed and its 

 place occupied by a fungoid mass, which protruded two inches beyond 

 the palpebral fissure. The surface of this mass was covered by a scab, 

 on removing which the tumour appeared formed of broken-down tissue 

 and new capillary vessels. 



Despite antiseptic treatment the growth continued, and attained 

 enormous dimensions. In June it was removed, and the wound dressed
