Observe the general form, and study the walls, of the various

The ventricles of the brain shown completely opened from above. The upper part of the cerebral 

 hemispheres, the corpus callosum, the fornix, and the tela chorioidea have been removed, and the 

 corpora quadrigemina, corpus pineale, and vermis superior laid bare. (After Toldt, Anat. Atlas, Wien,
