632 THE NEEVOUS SYSTEM. In frontal sections through the occipital and posterior temporal regions the tapetum stands out very distinctly (Fig. 559, p. 631; see also Figs. 565, p. 636, and 567, p. 638). Septum Pellucidum.âThe septum pellucidimi is a thin vertical partition which intervenes between the two lateral ventricles. It is triangular in shape, and posteriorly it is prolonged backwards for a variable distance between the body of the corpus callosum and the fornix, to both of which it is attached. In front it occupies the gap behind the genu of the corpus callosum, whilst below, in the narrow interval between the posterior edge of the rostrum of the corpus callosum and the fornix, it is prolonged downwards in the paraterminal body towards the base of the brain. The septum pellucidum is composed of two thin laminae in apposition with each other in the median plane (Fig. 562; Fig. 564, p. 635).

It varies greatly in size in different Ventricultjs Lateralis. The cavity in the interior of the cerebral hemisphere is called the lateral ventricle. It is lined throughout by ependyma continuous with the ependymal lining of the third ventricle. In some places the walls of the cavity are in apposition, whilst in other localities spaces of varying capacity, and containing cerebro-spinal fluid, are left between the bounding walls. The lateral ventricle communicates with the third ventricle of the brain by means of a small foramen, just large enough to admit a crow-quill, which is termed the foramen interventriculare. This aperture is placed in front of the anterior end of the thalamus and behind the column of the fornix. The highly-irregular shape of the lateral ventricle can be best understood by the
