No coro- nal and no lambdoid suture appears in this section; ^nd what is still more remarkable, although the section is supposed to pass through the very mid- dle of the sagittal or parietal suture, there is re- presented in the site of that suture, instead of the appearance of divided serrae, (with which every one is familiar, who has made a single vertical section of the cranium on the median plane) merely a layer of diploe inclosed between two tables, such as would haVe been disclosed in either parietal bone by dividing it a 1 ttle to the side of the median line Is it possible that the artist drew this re- presentation from a skull actually before him ? The view of the brain is no less inaccurate. The distance between the anterior commissure 61 and the commissure of the tractus optici is greatly too large; and the margin between 68 and 63 ought to be perpendicular instead of curved.
