Note 480 — Chapter XI

Fl. Petrie and Quibell, Nagada and Ballas, London, 1896; De Morgan, Recherches sur les Origines de l’Egypte, Paris, 1897–98, 2 vols. See for summary of the question: S. Reinach, L’Anthropol., 1897, p. 322; and J. Capart, Rev. Université, Brussels, 4th year (1898–99), p. 105. Let us remember while on this point that at the quaternary period lower Egypt was still covered by the sea, and that the climate of Egypt and the Sahara was much more humid than to-day (Shirmer, Le Sahara, p. 136, Paris, 1893). Most of the prehistoric finds in Egypt have been made on the table-lands, not covered by the alluvial soils of the Nile.
