DORSAL ASPECT OF TBE MESENCEPHALON. 441 TMSphaerac Dien., epen., meseii., meten. are abbreviations of diencephalon, etc. So much of the preparation as is not included therein belongs to the prosencephalon. Pfl'ra.—Postgeniculatum. Th.—Thalamus. The sides of all the coelise are beveled o& so as to expose their roofs more clearly. The widest portion is the metaccelia, whose proper roof (metatela) is so thin that the laminaB of the overhanging cerebellum show through it. The epicoelia presents two very different portions—a caudal, which is short but wide and high, reaching up into the cerebellum (PI. II, Fig. 4), and a cephalic, longer but nar- rower and lower, excepting at its cephalic end, where its roof, the valvula, rises to join the postoptici. The succeeding contracted portion represents the mesoccelia ; the next mesal cavity is the diaccelia, the roof of which presents the two parallel diaplexuses, diverging in the aula to connect through the portae with the proplexuses. On the right (left of the figure) the crescentic line representing the transection of the medicornu should reach the end of the line indicating the boundary between the hemi sphere and the postgeniculatum; see Fig. 121. The membranes and the relative areas of alba and cinerea are not shown. Fig. 114.—Dorsal aspect of the mesencephalon, exposed by the separation of the cerebellum and hemispheres; from Prep. No. 390, M. C. U. Objects.—To expose (A) the dorsal aspect of the mesencephalon, the cephalic aspect of the cerebel- lum and the caudal aspect of the hemispheres ; (B) the origin of the NN. trochleares from the cephalic part of the valvula («B.) ; (C) the caudal position and retroversion of the conarium. Preparation.—The fresh brain was carefully held and the caudal portions of the hemispheres gently pushed cephalad, the attachments
