    EXHIBITldN OF PREPARATIONS ILLUSTRATING (A) THE ENLARGEMENT, YET COMPLETE CIRCUM- SCRIPTION OF THE PORTA IN AN ALINJECTED HYDRENCEPHAL ; (B) THE CONTINUITY OF THE DIACCELIAN ENDYMA FROM THE MESAL SURFACE . OF THE THALAMUS OVER THE HABENA TO THE DIATELE ; (C) THE INSULA IN A DOG, MONKEY, CHIMPANZEE, AND PORPOISE. By BURT G. WILDER, M.D. Dr. B. G. Wilder then exhibited preparations of the brains of a dog, monkey {Cercopithecus), chimpanzee, por- poise, and man, and of an alinjected human hydrencephal,' illustrating these points : {a) that, contrary to what is ex- pressed or implied in most anatomical works, in the human brain (as in those of all other mammals examined with refer- ence thereto), the rima (the part of the great transverse fis- sure along which the proper nervous parietes of the proso- coele are abrogated and the endyma pushed entad before the intruding prosoplex) stops 1-3 cm. short of the tip of the medicornu (on this point see the N. Y. Med. Jour., April 5, 1884, P- 376, fig. 48); {b) in the human hydrencephal, not- withstanding the pressure which had more than doubled the normal diameters of the porta (orifice of communication between the aula and either lateral ventricle, commonly Jr^\\l' ''1'^ ^°°y''c equivalent of hydrocephalou! brain, I encoun- tered the analogous word hydreiicephalocele.
