Art. II .— Notice of the Rocks composing the Mountains which 
occur in the Desert between the Nile and the Red Sea. With 
a Sketch. (Plate VIII.) 
The sketch of the Desert between the Nile and the Red Sea 
(Plate VIII.), is from the pencil of a gentleman on whose accu- 
racy we place the utmost dependence. We give it in the hopes 
of its proving a useful guide to any future geologist who may 
happen to travel the same route. The journey across the De- 
sert, from the Nile to Kosseir, was performed in three days, 
halting only for two or three hours at noon and at midnight. 
The mountains in the centre are granite, porphyry, &c. One 
part of the road lay along the junction of the sandstone and pri- 
mitive mountains ; which line it was easy to trace by the eye 
for many miles, as observation was nowhere impeded by vege- 
tation or soil. 
The sketch was taken between the Nile and the Red Sea, 
about 100 miles from Ghinneh. The distant mountains at A 
(PL VIII.), are composed of limestone, alternating with dark 
beds of trap, impregnated with a large proportion of sand, flints, 
agates, &c. disposed at an angle of 10° to 15°. The hills at B are 
composed of a blue schistose rock, of about 45° NE. with occa- 
sional masses of greenstone, and a red porphyry or sienite, and 
sometimes asbestus. The beds at C, are composed of coarse brown 
sandstone, and lie under the limestone, in a parallel position, 
at an angle of about 15° N. They are separated by the beds 
D, composed of disintegrated greenstone, with white calcareous 
veins, forming a reticulated net-work around the nodules. These 
beds, C and D appear always to intervene between the schist 
and limestone. At E, there is a very singular appearance : a 
mass of perfectly white quartz is seen protruding itself into the
