[95] See M. Girard’s Observations on the valley of Egypt; and on the secular increase of the soil which covers it, in the great work upon Egypt, and Mod. Mem. t. ii. p. 343. On this subject we may further observe that Dolomieu, Shaw, and other respectable authors, have estimated these secular elevations much higher than M. Girard. It is to be lamented, that nowhere has it been tried to examine the depth of these deposits over the original soil, or the natural rock.
