formed if a number of small streams, instead of flowing into a largo 

 river, were suddenly absorbed by, comparatively speaking, an enor- 

 mously broad and consequently almost stagnant dyko of freshwater, 

 lying at right angles to their course, which of itself was capable of 

 little or no denuding force. 



In regard to tho heaping up of the shingle which forms the Chesil 

 Bank, Messrs. Bristow and Whitaker assume a west to east current, 

 moving the shingle in the same direction ; but, if so, why are the 

 pebbles larger at the easterly end of the Fleet, and why do they 

 gradually diminish in size, and terminate in sand to the west ? To 

 Ml'. Wilson these phenomena appear explicable only on the assump- 

 tion of a former current from east to west, even if the present cur- 

 rents be in the reverse direction. 



Fossils in the Budleigh-Salterton Pebbles. — Mr. E. B. 

 Tawney, F.Gr.S., writes to explain some misapprehension in re- 

 gard to his reported discovery of Budleigh-Salterton fossils in situ 

 at Anstey's Cove. Last summer he found on the coast, at Smugglers' 

 (not Anstey's) Cove, red and pale-reddish grits, containing casts of 

 the same fossils as occur in the red beds of the Hangman Grits of 

 North Devon, namely, casts of a large Myalina, and other bivales 

 with deep concentric lines of growth, numerous Univalves (Natica f), 

 Tentaculites, and String ocepTialus Burtini (with casts of the hinge). 

 Although not in such good condition as the Hangman Grit cast, they 

 are apparently the same. In this opinion he is confirmed by 

 Mr. Etheridge, who has identified the large Myalina and other bivalves 

 of the Hangman in some of the pebbles from Budleigh-Salterton. 



Exploration of the Leaf-beds in the Lower Bagshot Series 

 OF Hants a^d Dorset. — The Eev, P. B. Brodie, F.G.S., &c., 

 suggests that while the search for leaves is being carried on in this 

 deposit, the explorers should be on the look out for any fossil Insects 

 that may occur associated with them, or in the fine marls alternating 

 with the leaf-beds. Very few remains of this tribe have as yet been 

 recorded from our older Tertiaries. In his collection he has some 

 insect remains from the Bagshot series of Dorset ; they consist chiefly 

 of small elytra of Buprestidce, Curculionidce, and a single elytron of 

 one of the HolopidcB. Some rather indistinct forms were also exhibited 

 by Mr. G. Maw at the late meeting of the British Association at 

 Exeter. Mr. Brodie hopes that some of the members of the Na- 

 turalists' Club, recently established at Bournemouth, may be induced 

 to examine these beds for Insects. The apparent scarcity of their 

 remains in the Tertiaries generally is probably due to the want of a 

 more minute investigation of the beds than has hitherto been given 

 to them. 



The Stone-boring Controversy. — In reference to Mr. Eofe's 

 article in the January number of the Geological Magazine, Mr. D. 

 Mackintosh writes to state, on the authority of Mr. Gosse (Good Words 

 for 1864), and Mrs. Merrifield ("Natural History of Brighton"), and 

 from what he has himself seen near Exmouth, that the Pholasj
