NOTES AND QUERIES. 173 
[We sliould liave been glad to have been furnished by our corrcsjiondcnt with 
some fuller acconntof the geological, as well as of the administrative and convivial 
proceedings of this meeting. I'ossibly the former might have been preferable 
food for those of oiu- readers who had not the gratilicatiou of partaking of Mr. 
Nunn's excellent provisions. — Eo. Geol.] 
NOTES AND QUERIES. 
The Supposed Triassic Mammalian Remains.—" Dear Sir,— In the 
foreign correspondence by Dr. Phiiiscm in your last luuuber, I observe that 
Mr. Pentland, in writing to Mr. Elie de Beainnont, refers to my recent discovery 
of ancient Mannualia, and supposes tiiey are derived from the ' Triassic Bone-bed 
of Dumby, near Bristol,' but tlie beds in this locality belong to the Inferior Oolite. 
In a note you suggest their being from the Dolomitic conglomerate. As it is 
desirable there shoidd be no mistake as to their locality or geological position, 
I write to say they were found in a fissm'e of carboniferous limestone at Holwell, 
near Froine, and that as these were associated with the teeth of the Microlesfes, 
the vertebra^ and teeth of Tkecodontosaurus, and fish-remains of the genera .4 o-orfM-s, 
Uyhodus, Sauricthijs, Lcpidotus, Oyrolepis, &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 Microlesfes I have also 
found teeth of the Muschelkalk Placodus, the first indications I believe of this 
formation or its fauna being represented in this country. 
" I hope soon to communicate fuller information with reference to Triassic-beds 
in the West of .England.— Yours traly, Charles Moore, F.G.S., Cambridge- 
place, Bath." 
Age of Drift Deposits. — " Sir, — Observing that the last mmiber of The 
Geologist 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 quarter I can obtain the best information respecting the ' drifts' 
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 Yorkshb-e 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 dis.similar. I presume 
that drifts may be of very different epoclis ; but some more general notice in your 
valuable periodical may intere.st others liesides 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," gi-avels, and loams of newer age, the geology of which 
has not yet been j^roperly worked out, although we liebeve Mr. Prestwich has 
accumulated a considerable amount of material towards the elucidation of their 
histories. We shall l)e glad of every information and particulars of the " drift," 
gTavel, and brick-earth de])osits. — 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
