On testing the enucleated globe with thetransilluminator, and pressing the point of the latter tothe back of the eye, close up to the exit of the nerve, anentire loss of light transmission could be observed, whichwas immediately brought back if the transilluminator wasmoved more than 4 mm. from any side of the nerve.

Verhoeff, for the following pathologic descrip-tion of the growth: The specimen submitted for examination consists of theposterior half of an eye. Attached to the posterior wall,and completely covering over the optic disc, there is aglobular tumor with constricted neck which measures 1 greatest diameter. Its cut surface is irregularly buthighly pigmented. Microscopic examination shows thetumor to be a melanotic spindle-cell sarcoma presenting noespecially unusual features. There are a number of areasof necrosis, some of them old, from one of which a small 506 Greenwood : Sarcoma of Choroid not Demonstrable. hemorrhage has taken place. The choroid is invaded fora considerable distance from the main tumor. The sclerahas not been perforated. The optic disc has been com-pletely destroyed by the tumor, but the nerve-stern showsno invasion. The retina evidently remained adherent tothe tumor, but is now almost compl
