 frontal and parietal lobes. Perhaps, also, bundles from the 

 cortex at the entrance to the fossa of Sylvius and from the cornu

Posterior portion of right hemisphere, internal surface. By teasing out with forceps 

 the fibres of the posterior extremity of the corpus callosum (splenium Ccl*) is shown. 

 The round mass under the corpus collosum is the thalauius options, Tlio. From the wall 

 of the surrounding ventricle the tapetum, Tap, passes to the corpus callosum. In the 

 cut, too, is shown a portion of the fasciculus longitudinalis inferior, Fli. Beneath the 

 thalamus is the crnsta. B. The other letters refer to parts which will be explained in the 

 text later on. Keif, Vicq d'Azyr's bundle; Jtaf, fornix ; Cca, corpus candicans ; II', 

 optic nerve. The bundle of fibres called the forceps, Fcp, belongs to the radiation of the 

 corpus callosum. (After Henle.) 



ammonis (running their course in the fornix), A part of the 

 bundles of the corona radiata, however, do not go to the thala- 

 mus, but pass in front to the outside and back of it, to termina- 

 tions which lie deeper.
