Every now and then an observation is met with which corroborates this statement. The inheritance from one parent or the other of the shape of the skull, in a fairly pure form, has been noted a number of times.

Fleure and James in their study of the Anthropological Types in Wales, p. 39, make the following observation: “It may be said that certain component features of head form, in many cases, seem to segregate more or less in Mendelian fashion, but this is a matter for further investigation; we are on safer ground in saying that the children of parents of different head form very frequently show a fairly complete resemblance to one or other parent, i. e., that head form is frequently inherited in a fairly pure fashion.”

Von Luschan found still more striking evidence of this in his study of modern Greeks, which he describes in his Early Inhabitants of Western Asia. He has found that the children of parents of different head form inherit in quite strict fashion the shape of skull of one or the other parent, and that the population, instead of being mesaticephalic, is to-day as distinctly divided into two groups, dolichol- and brachycephalic, as in prehistoric times, in spite of the constant intermixture that has occurred.

15 : 29 seq. Professor G. Elliot Smith, The Ancient Egyptians, chap. IV, and pp. 41 seq. On p. 43 we read: “If we want to add to such sources of information and complete the picture of the early Egyptian ... he can be found reincarnated in his modern descendants with surprisingly little change, either in physical characteristics or mode of life, to show for the passage of six thousand years.” On p. 44: “Although alien elements from north and south have been coming into Upper Egypt for fifty centuries, it has been a process of percolation, and not an overwhelming rush; the population has been able to assimilate the alien minority and retain its own distinctive features and customs with only slight change; and however large a proportion of the population has taken on hybrid traits resulting from Negro, Arab, or Armenoid admixture, there still remain in the Thebaid large numbers of its people who present features and bodily conformation precisely similar to those of their remote ancestors, the Proto-Egyptians.” See also G. Sergi, 1, p. 65, and 4, p. 200.
