510 Notices of Memoirs — Bemhridge Limestone, Creechharroic. 



Pit III. 



{a) Surface soil. ft. i 



(6) Dirty gravel ......... B 



(c) Caking sand ......... 3 



{d) Large and small flints ........ 1 



[e) Brown, stiff, sandy clay ....... 3 



(/) Loose flint gravel ........ 2 



(gr) Black streaky clayey sand with flint-chips, concretions, and 



much manganese ........ 7 



(h) Hard irony crust ......... 



(i) Clayey sand with perished flints ; one large white dint at the 



bottom of the hole ........ 



Pit IV. 



(a) Vegetable mould ......... 



(6) Clay, sand, and gravel with very large flints up to 1 cwt. 



This much resembles the Middle Headon Venus Bed 

 (c) Drab sandy clay like that in brickyard ; not bottomed .

Pit V {about 10 feet beloiv the summit on the ivest side of the hill). 



(a) Surface soil. 



(b) Clay with angular flints 2 6 



(c) Very stiff hardened clay with pieces of rubbly limestone con- 



taining much manganese and soot-like patches . . .96 



(d) Fragments of Bembridge Limestone very rich in fossils. This 



was where I obtained the chief collection made during my 

 former visit. On this occasion we obtained a good specimen 

 of Unio, the first I believe, found at this horizon . . 2 



(e) Hard crumbling limestone ....... 7 



(/) Sandy clay . . .' 9 



(g) Grey sands with quartz pebbles and broken flints. On my 



former visit I found a large fragment of Bembridge Lime- 

 stone at a depth of 13 feet not far from this pit ..40

The lowest bed we touched was the drab sandy clay at the bottom 

 of Pit IV, wliicli is the same as that seen in the brick-pit, and the 

 thickness of which I estimate to be not less than 40 or 50 feet. 

 It seems to have been much used for dressing tlie laud, and we found 

 many old pits from which it had been obtained along the west side of 

 the hill. This clay I regard as the equivalent of the Lower Headon 

 formation. The coarse sand, which occurred above this, I take to be 

 the Middle Headon Venus Bed, while the mottled red and green clays 

 or marls wliich we found about 16 feet below the summit of the hill 

 much resembled the Osborne Series. 



Of the part of the hill explored by us I shoukl say that about 

 three-quarters ccmsisted of Oligocene strata and the rest of sand and 

 gravel. There is everywhere evidence of great disturbance of the 

 strata, whether we refer this chiefly to large movements of faulting and 

 overthrust, or the more superficial action of landslips, soil creep, etc. 



[We are glad to print the important details of the Creechbarrow 

 strata that have been obtained by Mr. Keeping, especially as they 

 confirm the original discoverv of our old friend Hudleston. (See
