NOTES AND QUERIES.

We shall be pleased to receive the Maastricht specimens alluded to, and to 
afford our correspondent any assistance in his investigations. 
The Petrified Trees at Lulworth Cove. — "Sib, — Would any of your 
readers inform me, through the medium of your ' Notes and Queries,' vfhether 
they have ever identified the strata e:ist of Lulworth cove, Dorsetshire, with Dr. 
Buckland's plate. No. 57, Bridgewater Treatise. I confess to having spent a day 
at this very interesting spot in the endeavour to find, but without success, some 
trace of what Dr. Buckland so minutely and graphically described, namely, ' the 
inclined position of the petrified stumps of large Coniferoe, and of the bed of black 
mould and pebbles in which they grew.' The latter (the dirt-bed) I had no 
difficulty in discovering, though not presenting a section of more than six inches ; 
but the petrified stumps of trees, as shown in Dr. Buckland's plate, were nowhere 
visible. I do not deny that in the position mentioned by him there are abundant 
remains of Coniferoe of an oblate spheroidal form, hollowed like a cone in the 
centre ; but these could not have been mistaken for the silicified trunks of trees 
with branching roots, figured in the work alluded to. — I am, Sir, yours truly, 
K. H. G." 
East Kent Natural History Society— " Dear Sir. — In the 'Notes and 
Queries ' of last month's Geologist, you state, ' 'We knew of tlie existence some 
years since of a Kent Natural History Society, the collection belonging to which 
was formerly at .Maidstone, and part is still, we believe, in the museum of that 
town, and part in the museum at Dover.' Now, to prevent any of the numerous 
subscribers to the Geologist from being disappointed at not finding any trace o; 
the Society, or the Natural History Museum, 1 beg to say that there never has- 
been a natural history museum in Maidstone, of a public character ; but a few 
years back, a gentleman of this town had an extensive private collection, which 
he kindly allowed the public to inspect, but whicli was afterwards sent to the 
Dover Museum, and no remnant of it now remains in Maidstone. As to tlie 
Society, I am sorry we could never muster strength enoU:;h to form one, but 
hope ere long, through the really invigorating effects of the Geologist, to succeed 
in doing so. — I am, Sir, yours truly, Civis, Maidstone." 
Stone to Bear a White Heat. — "Sir, — 1 take the liberty of addressing 
you, requiring information relative to stones of sedimentary formation that will 
stand white heat. If such a stone could be found it would be of great use (cross 
sawn) for raising heat. Perhaps some of your correspondents might give 
information if such stone be found here or abroad. — Very respectfully, Coli^ 
M'Kenzxe Dick, 52 Poland Street, Oxford Street." 
Plan fob Conducting a Geological Class.—" Sie, — If you, through the 
medium of your excellentmagazine, could inform me of the best, or of any method 
of conducting a class for the purpose of studying geology, I should be much 
obliged to you. — I remain yours respectfully, J. B. — Huddersfield." — The answer 
to such a question involves two considerations, whether the intended class is to 
be out door or in-door. Presuming it to be the latter, another point of considera- 
tion is, whether the course of instruct ion is to be long or short. If a short course, 
the geology may be gone into at once, and the principles upon which Sir Charles 
Lyell has framed his Manual may be most advantageously followed. If the course 
is to be long, subsidiary matter and details, as also the chemical, mineralogical, 
and other subordinate scientific phases of the science should be fully gone into. 
For this, Mr. Jukes's " Student's Manual " would give a good idea of a suitable 
plan. 
Contorted Fossils from Upper Bala Rock. — " Deak Sir, — I thank you 
for your kind attention to my inquiry respecting the "Scotch Drift," and 
enclosed I send you a little fossil which I cannot make out Will you kindly give me 
its name (if it has any) in your next number ? I found a great number of the 
same kind on a slab of Upper Bala (Sedgwick), at Cefn Coch, North Wales; all of 
them were pointing in the same direction. — Dear Sir, yours faithfully, D. C. 
Davies.— Oswestry." — The specimen received is a fragment of a trilobite com-
