Fig. 69, Experiment III. A figure corresponding with the level behind the 

 splenium of the corpus callosum showing the beginning of the calcarine fissure 

 and the well formed crescent shaped visual radiation; its dorsal horizontal 

 branch degenerated (vr), the visual fibers bending around the tapetum into the 

 upper lip of the calcarine fissure where they enter the striate cortex still occupying 

 only a portion of that fissure. Soma to-sensory fibers (sr), definitely separated 

 from the visual, enter the superior parietal convolution (PS). A few degenerated 

 eortico-fugal fibers pass between the bundles of the external sagittal stratum to 

 reach the internal sagittal stratum {tct = tractna cortico-tectalis). (Compare 

 with figs. 95, 96.)
