N0TE3 AND QUERIES. 173 



[We should have heen glad to have been furnished by our correspondent with 

 some fuller account of the geological, as \Yell as of the administrative and convivial 

 proceedings of this meeting. Possibly the former might have been preferable 

 food for those of our readers who had not the gratification of partaking of Mr. 

 Nunn's excellent provisions.— Ed. Geol.] 



NOTES AND QUERIES. 



The Supposed Trtassic Mammalian Remains. — "■ Dear Sir, — In the 

 foreign correspondence by Dr. Phipson in yoiu' last number, I observe that 

 Mr. Pentland, in writing "to ]Mr. Elie de Beaumont, refers to my recent discovery 

 of ancient IMammalia, and supposes they are derived fi'om the ' Triassic Bone-bed 

 of Dundry, near Bristol,' but the beds in this locality belong to the Inferior Oolite. 

 In a note you suggest their lie'mg from the Dolomitic conglomerate. As it is 

 desirable there should be no mistake as to their locality or geological position, 

 I -ttTite to say they were found iji a fissure of carboniferous limestone at llolwell, 

 near Frome, and that as these were associated with the teeth of the Microlestesy 

 the vertebrae and teeth of Tkecodontosauvus, and fish-remains of the genera, Acvodus, 

 Hybodus, Sauriclliys, Lepidotus, Gyrolcpis, &c., I have little doubt the conglomerate 

 is chiefly derived from beds of Triassic age, and that these mammalian remains are 

 therefore not so old as the Dolomitic conglomerates. 



" It may interest your readers to know that with the Microlestcs I have also 

 found teeth of the IVIuschelkalk Placodus, the first indications I believe of this 

 formation or its fauna being represented in this countiy. 



" I hope soon to communicate fuller information with reference to Triassic-beds 

 in the West of , England. —Yours truly, Charles Moore, F.G.S., Cambridge- 

 place, Bath." 



Age of Drift Deposits. — Sir, — Observing that the last number of The 

 GeoloCxISt contains rather scanty notices under the head of ' Queries' from corre- 

 spondents, and deeming them of some importance to the uninitiated, permit me to 

 ask from what cpiarter I can obtain the best information respecting the ' di'ifts' 

 which are now and then met with in different parts of this country. For instance, 

 may I conclude that the drift in the vicinity of Thirsk in Yorkshire is of the same 

 age as the drift-beds at Barrow in Leicestershire, resting on the Lias ? You will, 

 perhaps, be amused at the question, as the contents are dissimilar. I presume 

 that drifts may be of very different epochs ; but some more general notice in your 

 valuable periodical may interest others besides myself. — G. W. Wakefield." — 

 In the new diagram map of the British Isles published this day, and which 

 has been executed under my direction, the range and course of the Great Northern 

 or Glacial Drift is laid down, as far as our present knowledge goes. There are 

 local and other " drifts," gTavels, and loams of newer age, the geology of which 

 has not yet been properly worked out, although we believe Mr. Prestwich has 

 accumulated a considerable amount of material towards the elucidation of their 

 histories. We shall be glad of every information and particulars of the " drift," 

 gravel, and brick-earth deposits. — Ed. Geologist. 



Localities for Fossils around London. — Dear Sir, — " There are a great 

 many students in Geology, who, like myself, can find little time for running far 

 into the country in search of practical knowledge during the academical portions 

 of the year, but who could nevertheless occupy an afternoon occasionally, and to 

 great advantage, in studying such formations of fossils as are to be met with 

 round London. But it is difficult for a beginner to find out these places, and I
