NOTES AND QUERIES.

Professor de Koninck, at Li6ge, and intend to be the bearer of some deeply interest' 

 ing forms from this district, as well as two perfectly new crinoids just discovered in 

 the greensand of the classical Iguanodon-quarry, at Maidstone, by W. H. Bensted, 

 Esq., and which that gentleman, with the disinterested liberality of all 

 true lovers of science, has placed at our disposal, to examine and describe. On 

 this subject 1 would wish to promise your readers an early notice. — Yours very 

 truly, Edward Wood, Richmond, Yorkshire." 



Private Collection. — Exchange of Fossils.—" Sir, — I was glad to find, 

 in your June number, that you proposed giving illustrations, &c., of all the 

 British Fossils, as such an arrangement will be of advantage, both to myself, 

 like your con espondent Amator Xaturje, as well as more of your readers in 

 this neighbourhood, that I am acquainted with. I have a good collection 

 of fossils out of the mountain-limestone; but, owing to the more expensive 

 books being beyond my reach, I am unable to arrange and classify them 

 accurately. "Were these named, having plenty of duplicates, I should be able to 

 exchange, as I see from your advertisements and correspondents gentlemen 

 are willing to do so, for named specimens. I may add that I shall be happy to 

 show my collection to any brother geologist who may call upon yours, &c., Jno. 

 Froggatt, Churchgate, Stockport." 



GEOLoaT OF Hay (South Wales). — Sir,— "Every month I hail with sincere 

 pleasure the arrival of the Geolo&ist, and feel much affection for the sturdy old 

 Mammoth which so appropriately adorns the cornei', because he is the harbinger 

 of a variety of new and interesting information which every lover of "the 

 hammer " must be glad to obtain for the reasonable sum of one shilling. Like 

 most enquirers, I am always happy to meet with a good deal of information in a 

 small space, and therefore invariably in the first place digest the matter contained 

 in that pre-eminently useful portion called "Xotes and Queries," leaving the 

 separate articles to be conned at leisure. Being a subscriber and an embryo 

 geologist, perhaps I may trouble you with tlie following queries ? 1. AMiat por- 

 tions of the Old Red Sandstone is it that abounds in this locality, and what 

 fossils (if any) does it contain ? 2. Quantities of gravel abound in some of the 

 valleys — a section 20 feet in depth, containing a large stone, probably half a ton 

 or more in weight, being exposed not a quarter of a mile fi'om Hay. Is this a 

 portion of the boulder-drift ? 3. In my rambles I frequently meet with a dark 

 browm sandstone filled with casts of minute shells, the two most conspicuous im- 

 pressions being a small spiral one, about a quarter of a inch in length, and a 

 bivalve, not unlike a Terebratula, onl^r broader, and about half an inch long. The 

 stone is always water-worn, and is found in abundance. I should be greatly 

 obliged if you could say what the impressions are. — I am, Sir, your most obedient 

 servant. Hay, South Wales." — To the south and east of Hay the cornstones, or 

 calcareous middle portion of the Old Red of Herefordshire crops out. In the north- 

 west, the lower portion, consisting of red marl and tilestones, comes out, resting 

 on the Silurian rocks of Radnorshire. The cornstones should be examined for 

 remains of Cephalaspis, and the other curious fishes and crustaceans of the Devonian, 

 or Old Red period. The tilestones are likely beds for similar remains, together 

 wath Lingulce and some other small shells ; also plant -remains, such as have been 

 found near Ludlow. 2. The gravels and boulders near Hay are of local origin, and 

 not a portion of the great " northern drift." They are derived from the Silurian 

 and Trappean rocks of the Radnorshire hills, and from the remains of some of the 

 Old Red beds themselves. 3. The water-w^orn fragments of shelly rock referred 

 to may possibly be portions of some of the fossiliferous lower tilestones, with 

 Holopella, &c. 



Geology of Callander. — " Sir, — I should feel much obliged if you would 

 inform me, whether the Old Red Sandstone in the neighbourhood of Callander, 

 N.B., is fossiliferous ; and if so, I should be glad of some information as to the 

 prevailing species to be found there. Perhaps some reader of the Geologist 

 would kindly inform me. — Yours, J. R. Stockport." 



BiruMiNoos Shales of Scotland, — "Sir, — I should be obliged if any of your 

 correspondents acquainted with the bituminous shales of Scotland, more especially
