veins, and faults is added. The author concludes that there is good 

 prospect of coal in the Shapur area, where Coal Measures are known to 

 occur, and that there is a reasonable hope of the Measures being found 

 in the other places where search is being made. On the Lower Nar- 

 bada the probabilities are less, but sufficient to justify a trial. P. D.

The general structure of the region traversed is noticed ; and remarks 

 are made on rock-specimens brought home, some of which have been 

 examined microscopically. Evidence is given that the Gulfs of Suez 

 and Akaba are rising ; there are notes on the formation of the Wadis, 

 and on the denuding and polishing action of sand. Mt. Baghir, or 

 Jebel el Nur, identified by Dr. Beke as the true Mt. Sinai, and believed 

 by him to have been an active volcano during the historic period, is 

 shown to be a granite hill, traversed by dykes of dolerite. (See Geo- 

 logical Eecord for 1874, p. 131.) W. T.

 The bitumen is in beds about 0-20 metre thick, alternating with very- 

 thin clay bands ; they dip 40°, 10° S. of W. In 22 days 485 tons of 

 bitumen was extracted by means of levels. The substance is valuable 

 for steam and gas purposes. Its principal locality is Herboul. Near 

 Erbille is a thick bed of bituminous limestone ; and at numerous points 

 between Kerkouk and the latter place petroleum has been noticed.

Fossils found on the shore of the Yang Namcho Chedino, or Tengri 



Nur Lake, 15,190 feet above the sea-level, were considered by Prof. 



Oldham to be not older than Cretaceous, and probably Nummulitic, 



allied to Sindh and Panjab Nummulitic fossils. R. E., Jun.
