1 That melanotic sarcoma in the eye is a fairly malignant tumour, and it occurs usually in the "cancer decade" of life. 2 It is invariably pigmented, and is usually of the spindled cell type, but may be of mixed celled variety. 3 That a fair number of cases of this condition are diagnosed accidentally in the laboratory (Terrien quotes "at Moorfield, oat of 82 cases enucleated for absolute glaucoma, 50jo were sarcomas, and these were not diagnosed beforehand ") , and so there is room for improvement in our diagnosis. 4 That every blind eye of unknown cause, and where the fundus cannot be examined, should be enucleated and examined macroscopically and microscopically. All enucleated eyes should always be thus examined. 5 That the use of radiograms may be helpful in the diagnosis of the primary as well as the metastasis in this condition. 6 That the tumour is usually large in size when first seen, and in view of the uncertainty as to the time of its existence, it may be prudent to exenterate the orbit in every case of intra- ocular melanotic sarcoma.
