In going over the other pages I also found another example that was most suggestive:
The one in the middle has predominantly Neanderthaloid traits, relieved only slightly by the bulge of the forehead. In this example and the one at top, the transverse section through the cranium is distinctly broad and round, a Neanderthal trait. In this set I would also say number 9 has some distinctly African traits and number 15 central-Asiatic of the "Premongol" series.
