Dr. Philippe Rey has made an investigation upon the weight of the cerebral lobes, and some of his conclusions will be of interest. Of the 347 subjects examined, 231 were men, 116 women. While the total weight of the right hemisphere predominates over that of the left, the left frontal is heavier than the 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 69.65 grains, which constitutes 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 Norma sagittalis is obtained by sawing the skull through the median line and observing the border of the cut within the sagittal suture. Dr. Lissauer, by means of a special craniograph, 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 different segments, and also certain of these lines with the horizontal, extending from the point named to the external 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 different processes and materials. The tables appended to the investigation exhibit enormous variations in the results, as a few examples will show. The following table gives the people, the author, the number of crania examined, and the average contents in cubic centimeters.

This study of Dr. Welcker's is worthy the attention of all anthropologists:

The next point which Mr. Welcker considers is the so-called modulus (found by adding the three diameters of the skull) and its relation to the cubature, in dolicocephalic, mesocephalic, brachycephalic crania.

Chapter III discusses the cubature of the skull as well as its height and width among different peoples. Six pages are devoted to a table of these three measures upon different races. The table of cubatures, on pages 106, 107, represents the different races arranged in the order of the contents of the skull.

Chapter IV is devoted to the cephalic index. Table IV, page 126, like the one just mentioned on page 106, exhibits in a graphic mauner the various races according to the cephalic index. This table is introduced in order to exhibit the author's method of graphic illustration.
