Human CEREBRAL FISSURES, THEIR RELATIONS AND NAMES 
AND THE METHODS OF STUDYING THEM.—In 1873 Professor Wilder 
tead before the Amer. Association for the Adv. of Science a 
Paper on the fissures of the Carnivora. Since that time he has 
Prepared for the museum of Cornell University many human 
brains, foetal as well as adult, and of several races; has examined- 
nearly all the literature of the subject and published several 
Papers on special points, the latest being “ On the paroccirital, a 
newly recognized fissural integer” (Jour. of Nerv. and Mental 
Visease, June, 1886), and communications before the recent meet- 
ing of the Am. Neurol. Assoc. While far from satisfied on cer- 
tain matters, since each fissure should be monographed, the con- 
clusions now presented are, he believes, worthy of consideration. 
The study of the human fissures should be preceded by the study

by learning certain fissures before others. The “landmarks” bc

tudied are the ten interlobar: Sylvian, presylvian, central, cir-
