Abstract
I. G eneral D escription The work of Geheimrath Karl A. von Zittel, as a member of the Rohlfs Expedition of 1874, has furnished us with an accurate geological description of the western oases of Egypt, which we can use as a starting-point for the further exploration of the Libyan Desert to the north and south of them, and his detailed sections and lists of fossils are of invaluable assistance in correlating the strata met with in various parts of this area Still, I cannot find that much has been done since Dr. Zittel's work except by Dr. Schweinfurth, Sir J. W. Dawson, Prof. Hull, Prof. Walther, Prof. Mayrer-Eymar, and Mr. E. A. Floyer in the Fayum, the Nile Valley, and various parts of the eastern desert, while the western desert seems to have remained almost unexplored In December 1893 and January 1894, when on a patrol visiting the oases of Kharga and Dakhla, and the desert routes to the south of them, I had opportunities of making a few observations in this portion of the desert which are, I venture to think, of some interest These I have more recently (April 1894) been able to amplify by a ride through the more nothern part of this western desert, the easternmost monastery in the Wadi Natrum or the Valley of the Natron Lakes; thence along the valley some 20 miles to Dêr Baramus, the westernmost of the four Coptic monasteries. From this point I turned S.S.W. and went as directly as possible
