We have only been able to give occasional attention to subjects pertaining to natural science. Yet I have not neglected to collect specimens of stone and soil from all important localities, especially during trips into the remote mountain regions. A chemical investigation and comparison of the specimens of Nile mud collected from different spots and under different conditions will perhaps be of interest. We have visited the old alabaster quarry of El Bosra, opposite Sioot, which has recently been discovered by the Bedouins and is now worked by Selim Pasha. We found there an inscription on the rock dating from the beginning of the eighteenth dynasty. We have also visited the quarries of granite and of “breccia verde” at Hammamât, which have been in use since the most ancient times, as well as the porphyry and granite quarries on Gebel Duchàn (Mons Claudianus, Mons Porphyrites,) in the eastern mountains of Egypt, (see page 160) which were celebrated in Roman times. We have brought back specimens of rock from them all. The most valuable blocks of “breccia verde,” of every size, lie directly on one of the finest and most convenient desert highways, two days journey from the Nile, and would be excellently adapted to removal and exportation. On account of our antiquarian aims we were especially interested in the opportunity of becoming acquainted with the present world of animals and plants in the southern regions of Nubia, which conspicuously resembles the representations on the most ancient Egyptian monuments. It scarcely appears possible to account for this except by the assumption of a universal recession of the more highly developed forms of natural life in the Nile valley from the north towards the south.
