Thus we see a tangible physical trait, avowedly due to heredity, obeying the same principle as the mental and moral qualities, tending on the whole to become eliminated as time goes on, since the entire number in each successive generation was certainly increased, while the proportionate amount of its appearance is less and less, still skipping about, however, and occasionally reappearing with almost equal force in those who inherited it at all.

I have examined the portraits of some three hundred other members of the royal families and find the same principles evident—that one sees strong general facial resemblance usually only among the closely related—but that striking peculiarities may jump a generation or two, and then reappear in some of the descendants. Also one sees that general blends are not common, but that each child tends to 'favor' one or the other of its parents or more rarely a distant ancestor.
