ANTHROPOLOGY. ^21 



Dr. Pbilipi)e Key has made an iuvestigation ui)ou the weight of the 

 • cerebral lobes, and some of his conclusions will be of interest. Of the 

 347 subjects examined, 231 were men. IIG women. While the total 

 weight of the right hemisphere ])redominates over that of the left, the 

 left frontal is heavier than th(^ right. The right occipital is slightly 

 heavier than the left. The difference of weight for the entire anterior 

 region between men and women amounts to G9.(J5 grains, which con- 

 stitutes a large proportion of the general cerebral excess of weight in 

 the male sex. 



Dr. Lissauer has added the sagittal suture to the other portions of 

 the human cranium which have been used in obtaining anthropological 

 measures. The sagittal curve or Xorma sagittalis is obtained by saw- 

 ing tiie skull through the median line and observing the border of the 

 <'ut within the sagittal suture. Dr. Lissauer, by means of a special 

 crauiograph, obtains the profile of the sagittal line on the anteropos- 

 terior median plane of the skull. Certain points are fixed on the per- 

 iphery, and by comparing them among themselves and in relation to 

 a central point located at the intersection of the vomer with the lower 

 face of the sphenoid, he obtains angles by means of which he compares 

 the relative value of the diflerent segments, and also certain of these 

 lines with the horhontal, extending from the point named to the exter- 

 nal occipital protuberance. A new vocabulary is introduced which will 

 add much to the complexity of craniometry. The ethnic results of the 

 paper may be thus set forth :

Dr. Herman Welcker, in Halle, has made a study of the capacity of 

 the cranium in connection with the three diameters. He first examines 

 carefully the methods employed for the curvature of the skull by 

 difterent processes and materials. The tables appended to the investi- 

 gation exhibit enormous variations in the results, as a few examples 

 will show. The following table gives the people, the author, the num- 

 ber of crania examined, and the average contents in cubic centimeters.
