top of the high plateau, which the Nile has since cut down through 
to a depth of 1400 ft.—( Petrie.) 
The plateau paleoliths go back to a time when the desert was still 
covered by streams which formed breccias.*—(Sayce.) 
Paleolithic man continued in Egypt till the Nile was as low as its 
present level. ‘We see Paleolithic man scattering his massive 
flint weapons, until the age of Nile mud (beginning about 7000 B.C. ) 
made agriculture possible, and a Caucasian race ousted the Palzo- 
lithic folks, whose portraits were left us in the figures found in the 
earliest graves. We see this oldest race of man to have heen of the 
Hottentot type, but even more hairy than the Hottentot, with the 
traces of his original northern habitation not yet wiped off by 
tropical suns.” —( Petrie.) 
Paleolithic man left worked flints in large numbers on the high plateau, 
associated with the flakes struck from them, round the centres where 
they were actually worked; but they all lie on level ground with no 
wash either way ; the denudation of the soil after a rainy age being 
by wind and sun-crumbling. —(Petrie.) 
Of the flints from the Wady es Sheikh and Wady Sojoor many are 
identical with those from the high Egyptian plateaux and from 
Europe. Fig. 4, for instance, which is a pure Chellean ‘knuckle-

duster,’ is almost indistinguishable from a paleolith from Somali- 
land, figured on Plate ix. fig. 1. Journ. Anthrop. Inst., vol. xxvii. 
(1897) ; while figs. 39 and 40 [figs. 5 and 6, p. 58] from the Wady 
Sojoor are to all intents identical with the “mells” or pounders 
from the Knysna Cave i in South Africa “made by previous genera- 
tions of existing natives.”—(Seton-Karr’s collection.) 
Implements of true Paleolithic form—and sharp as the day they were 
made —are associated in both the above-named Wadys with others 
of a more Neolithic facies ; the patina of the latter being often as 
deep, if not deeper, than that of the former, both categories being 
of the same material and lying together in the same workshop, 

* My friend Sir H. Howorth reminds me that streams do not form breccias except 
in mountain torrents ; but that the formation of the breccias, however, shows a very 
different condition of things from what now prevails.
