 The author advises a boring at Hunstanton, which would probably 

 not exceed 1000 feet before touching Palaeozoic rock, from the absence 

 and thinning-out of beds, and from the Chalk having been upheaved 

 1700 feet from Yarmouth to that place, bringing the beds beneath so 

 much the nearer to the surface. He also gives reasons for believing it 

 probable that Coal Measures exist there. This paper has been pubhshed 

 somewhat more fully in Proc. Geol. Assoc, vol. iv. p. 35 (1875). W. W. 



GuNN, J. On the Pile-driving in Wroxham Little Broad, and the 

 lUusti'ation it affords of the mode of formation of the Valleys of the 

 Bure and the Wensum. (Norwich Geol. Soc.) Norwich Mercury, 

 no. 8390, p. 3. 

 The greatest depth to which a pile was driven through the marsh was 

 72 feet beneath the level of the water. The depth of water is about 

 8 feet ; therefore the bottom of the water was once 66 [64] feet lower 

 than now. The cause of this excavation is thought to be due to alter- 

 nate elevations and depressions, during the former the excavating power 

 of water being increased, and during the latter materials being depo- 

 sited and turbaries formed, some parts remaining as broads. On either 

 side of the valleys are the same formations, out of which the valleys 

 have been scooped, which process the author thinks to be principally 

 due to submersion under the glacial sea, aided afterwards by fluviatile 

 and atmospheric action. The occurrence of Hint-implements in the 

 valley -gravels is noticed. W. W.

Notices the finding of the largest known specimen of Voluta Lam- 

 herti (9 inches long) in Coralline Crag at Aldborough, and of a horn, 

 apparently of an early form of Cervus elapJius, in the same bed at 

 Gedsgrave. Alludes to the advantages of Hunstanton as a place for a 

 trial-boring to find the Palaeozoic rocks, remarking that the bore might 

 begin there in Kimeridge Clay, which was not reached for 290 feet in 

 the Netherfield bore. W. W.
