    cupied by small accumulated cells or gran/ides, which were dotted vn thei/r mterior and partly prodded with manifest nuclei. In the stratum gangliosum (gl) Layiso- lated, larger rounded cells, with large nuclei, which re- presented preserved ganglia, and whose interstices were filled with the small, round, dotted cells previously al- luded to. On the limitans interna, thick-set and delicate filaments were inserted perpendicular to its surface. Sev- eral of these forced their way in a winding direction through the small cells. These filaments are to be re- garded as the preserved radiating fibres of the retina (Fig. 2, f). The gray or 'molecular layer (gr) was con- siderably shrunken and very uniformly and minutely dotted. On this layer a few of the round elements of the granular layer had intruded, and had, in several places (a), pierced the gray layer itself, protruding into the ganglionic and fibrous layers. The two granular layers (ik, ak) were greatly enlarged, mostly at the ex- pense of the intergranular layer (zk), which latter was dotted in its appearance, and contracted to a narrow, but everywhere plainly recognizable strip. In the granular layers, round dotted elements, differing in no manner from the normal granules, were situated; these did not lie very densely together, a small interspace, filled with a fine granular substance, separating the different granules. The radiating fibres, however, were but sparingly sup- plied in most places in the granular layers. In the inter- nal they were almost entirely absent, and in the external only traces of their former presence were discoverable. The limitans externa (le) was preserved; the same can
