Raises the following objections to the proposal : — 1. The Blad-el- 



Djerid and the Oued-Rir would be submerged or incrusted with salt ; 



2. The amount of salt in the superficial and underground waters of 



the Eastern Sahara would be increased ; 3. A great climatal change 



would possibly occur in that region, which is the principal centre of 



the date -culture. G. A. L.

Shows that the depression in question was never any thing but a 



salt lake, unconnected with the Mediterranean in historical times. 



The author believes that when this lake existed the climate was very 



different and more humid than now, and does not beUeve in the 



practicability of the proposed inland sea. G. A. L.
