confined to the mere averages of indices. We may illustrate in this connexion the
nature of the conclusions to which the Sergian system may sometimes lead by a reference
to the classification of the Egyptian skulls in the Naples Museum. Professor Sergi
found (A frica, pp. 50-64) that out of the 86 specimens forming the collection no less
than 21 were of the single form which he styled at that time ‘ Sphenoides aegyptiacus ’
and which he now calls ‘ Beloides aegyptiacus.’ This is a striking example of the
employment of his classification, for much more information is conveyed by the statement
that these 21 skulls are all of exactly the same shape than would be given by the mere
publication of their several cephalic indices. The review of the Naples collection is
further interesting as corroborating the opinion that forms divergent from the Ellipsoidal
and Ovoidal are commoner in the later than in the earlier periods, for the collection,
whatever its precise composition may be, can hardly include any Predynastic skulls,
inasmuch as no archaic cemeteries had been explored at the time when it was formed.
