F. Hume, in a discussion of the formation of the oases-depressions, refers to the importance of soft and hard strata, and to the action of folding in exposing the former to the agents of denudation. This is striking confirmation of the views promulgated by me since my first acquaintance with the oases many years ago. Of great interest and value, being new, is the suggestion that the topography of the southern oases and surrounding desert may be, to a considerable extent, due to denudation acting on the country as it was in process of being elevated from the sea in which the deposits forming it had been laid down.] [Footnote 4: The dates given in this chapter are those assigned by Professor Steindorff.] [Footnote 5: Canon Rawlinson’s translation.]
