    TRANSACTIONS OF THE ON TWO LITTLE-KNOWN CEREBRAL FISSURES, WITH SUGGESTIONS AS TO FISSURAL AND GYRAL NAMES. By BURT G. WILDER, M.D. In all adult human brains examined with reference to them in the anatomical laboratory of Cornell University, there have been found, more or less distinctly marked, two fissures which are seldom figured or described, but which probably have considerable morphological significance. The one indents the dorsimesal margin just cephalad of the precentral fissure and paracentral lobule. In the brain exhibited (from an adult mulatto) it is particularly distinct, and is shown in the outline figure in the N. Y. Med. jfour., Feb. 23, 1885, fig. 42. It seems to have been described by Lussana and Lemoigne ( Fisiologia dei centri nervosi ence- falici, Padova, 1871, fig. 177,) as Solco inflesso; paronym- ized, in Latin this becomes fissura inflecta, and in English the inflected fissure. At first glance it strongly suggests the cruciate fissure of the Carnivora, especially when the branches of the precentral border what resembles the sigmoid gyrus; but such a homology must not be admitted without further investigation. For some of the difficulties involved see the Transactions of this Association for 1883, p. 63. The other fissure is likewise well developed upon the brain exhibited, which was hardened within the skull by arterial alinjection, and hence escaped the injury and distortion which are sometimes inflicted upon the base, during the ordinary processes of removal and preservation. The fissure appears upon the meso-ventral aspect of the temporal lobe, near its tip, extending caudad for 1-3 cm. from the horizontal por- tion of the Sylvian, between the ventro-cephalic ends of the Reprinted from the Journal OF Nervous and Mkntal Disease, Vol. xii., No. 3, July, 1885.
