Extract

While investigating the relies of early habitations at Beraeis, near Jebel Katul, 100 miles N.W. of El Obeid, northern Kordofan, Dr. C. G. Seligman found a number of implements all made of a finegrained, blue-grey stone, quantities of which he found at the base of Jebel Katul. A fragment of this stone was examined by Dr. G. T. Prior in 1912, and found to be rich in riebeckite.
