    Under the Raphe of the Corpus CaUosum, is placed the Septum Lvcidum, which, when viewed laterally, is observed to be broad before, curved at its edge, and to become gradually narrower towards its posterior ex- tremity. It is connected above to the Corpus CaUosum, be- low to the Fornix, and forms a distinct partition be- tween the lateral Ventricles. It is formed of two Cineritious and Medullary La- mince, more or less separated from each other at their fore-part, by a small Cavity, called Fissure, or Fossa of Sylvius, or Sinus of the Septum Lucidum, which, however, does not communicate with the Lateral Ven- tricles, though in some subjects it reaches a consider- able way backwards, and, as well as the other Cavities of the Brain, has been found full of water in Hydroce- phalus cases. Under the Septum Lucidum is placed the Substance which has been compared in shape to a Vault by tin; Ancients, and from that has obtained the name 01 For- nix. The Fornix is merely a continuation of the Corpus CaUosum, and forms a sort of hollow Ceiling-, with four Pillars called Crura, or Cornua, flora their winding di- rection, of which there are two anterior and two pos- terior. The two Anterior Crura are short, run close together, and become enlarged ^t their inferior parts Tlie two Posterior Crura are long, considerably distant from each other, and form Curvatures which correspond with the course of the Inferior Cornua of the Lateral Ventri- cles. That part of the Crura Fornicis lying in the Inferior Cornua of these Ventricles, forms thin borders, getting the name of Corpora Fimbriata ,- but, | < the Vic D'Azyr, they arc more properlj ten ;, from being united with tiie great \. campus.
