Some smaller flat (/j) and round(^„) tumors were seen in other places on the outer surface of theretina. The other half of the retina showed only a few small tu-mors, having the appearance as those represented in Figure other parts of the specimen exhibited nothing unusual to thenaked eye. Under the microscope all the tumors were composedof small, round cells, embedded in a scanty matrix, and sup-plied with many thin-walled blood-vessels—the ordinary structure. Fig. I. Retinal Glioma. 9 of retinal glioma. Transverse sections through the smallest tu-mors showed, with greatest distinctness, that the pseudoplasmoriginated in the inner granular layer. Figure 2 illustrates thiscondition. The inner granular layer {j) swells by accumulation of element-ary parts which cannot be distinguished from its own. Theouter granular layer {o) is raised. At the crest of the intumes-cence the intergranular layer (;/) disappears, and the tumorblends with the outer granular layer. The molecular layer (;//)is barely indicated, and the ganglionic layer is absent. Thefibrous layer (/) exhibits marked alterations. The radiating pillarsof connective tissue are well preserved, and are attached to the
