believe, taking place is much greater than in the Sunderland ease, the borings for 
salt being from 1000 to 1200 feet deep. 
I will conclude with a quotation from my paper on the Breccia-Gashes ! (p. 
174): ‘The forms of these gashes, which are gullet-shaped and tapering down- 
wards, unlike the sea-cayes ; the breccia with which they are filled, the matter with 
which the fragments are cemented, the half-broken beds which so often bridge over 
the upper portions of the fissures, and the unbroken beds immediately above and 
below them, which would be inconceivable had the fissures and their infillings been 
due to real earthquakes—all these things are necessary accompaniments of the 
rock-collapses which, it has been shown, must in time past have happened fre- 
quently, are happening still, and must happen more and more frequently in the 
future,’ 
4. Notice of an Outline Geologicel Map of Lower Egypt, Arabia Petrea, 
and Palestine. By Professor Epwarp Huit, LL.D., F.R.S., F.G.S. 
The map exhibited was enlarged from that which accompanies the author’s 
book ‘Mount Seir, Sinai, and Western Palestine,’ giving a narrative of the ex- 
pedition sent out into these countries by the Palestine Exploration Society in 
1885-84. It embraces a region extending from the valley of the Nile on the west 
to the table-land of Edom (Mount Seir) and Moab, including the Jordan-Arabah 
Valley, and the mountains of Sinai. Its northern limit is the Lebanon. ‘The fol- 
lowing formations and divisions are represented :— 
1. Sandhills of Lower Egypt, the coast of Palestine, 
( and Arabah Valley. 
. Alluvial Deposits of the Nile, the Ghor, and Jordan 
Valley. 
. Gravel of the Wady el Arabah.

As an outline of the scientific results which were arrived at by the members of 
the expedition, and which are represented on the map, had already been communi- 
cated to the Association,” it was not considered necessary to repeat them here, but
