[Footnote 1: In geology, the term _rock_ is applied alike to the soft
and hard materials composing the earth’s crust, as sands may pass
into solid sandstones, soft muds become the most tenacious of clays,
and hard basalt originate as a molten lava.]
[Footnote 2: This statement may not absolutely apply to Cairo itself,
seeing that in the disturbed region of Abu Roash sandstone is actually
at the surface, and the clays are less conspicuously developed than
is the case to the south.]
[Footnote 3: Figs. 1, 2 and 4 are based on photographs of localities
in Great Britain and Ireland taken for the Geologists’ Association
collection of photographs.]
[Footnote 4: Farafra is an exception to this rule, the depression
being due to the wearing away of soft Cretaceous beds higher than
the sandstone.]

[Footnote 7: At Abu Radham a dark layer of purple iron ochre seems
to have been the cause of the investigation.]
