    The Centrum Ovale of Vieusserts. This is the Medul- lary Substance of the Brain, forming a kind of Nucleus, which is seen after removing the Cineritious Substance, and all the Medullary parts mixed with it, which lie between the Cortical Convolutions. To obtain a proper view of the Centrum Ovale, the Nucleus ought to be cut in such a manner as to pre- serve the Corpus Callosum, and the same convexity with that of the general convexity of the Brain. The Centrum Ovale forms an arch or roof over the two Lateral Ventricles ; and the under part of this roof which is smooth and uniform, constitutes the upper part of these Ventricles. Vieusserts considered the Centrum Ovale as the great Dispensatory of the Animal Spirits. The Ventricles of the Brain are four in number, two of which are called Lateral. The four Ventricles have their sides contiguous to each other, are ehiefly formed of Medullary Matter, and are lined with a continuation of the Pia Mater, which differs from that covering the exterior surface of the Brain, in having fewer vessels dispersed upon it. They are constantly moistened by a Fluid, which prevents their opposite sides from adhering to each other. The useo? the Ventricles, like many other parts of the Brain, is still unknown. The Lateral, formerly called Superior Ventricles, are situated in the Hemispheres, one in each, and run ho- rizontally in the same direction with the Hemispheres themselves. They are of an irregular form, lying under the Cen- trum Ovale, and have each three winding corners, com- pared to Ram's Horns, which are therefore called Cor- The Anterior Cornua zvo. separated only by the Septum Lucidum. The Posterior Cornua, called also Digital Cavities, are at a considerable distance from each olher, but ap- proach nearer at their pointed extremities ; while the inferior Cornua, the beginning of which is seen, run ards and forwards, and terminate in the Lateral Lobes of the Brain.
