We shall be pleased to receive the Maestricht specimens alluded to, and to 

 aflford our correspondent any assistance in his investigations. 



The Petrified Trees at Lulworth Cove. — " Sib, — Would any of your 

 readers inform me, througli the medium of your ' Notes and Queries,' whether 

 they have ever identified the strata east of Lulworth cove, Dorsetshire, with Dr. 

 Buckland's plate. No. 57, Bridgewatcr Treatise. I confess to having spent a day 

 at this very intei'esting spot in the endeavour to find, but without success, some 

 trace of what Dr. Buckland so minutelj' and graphically described, namely, ' the 

 inclined position of the petrified stumps of large Coniferee, 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 Coniferse 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. n. G." 



East Kent Natural History Society— " Dear Sir, — In the 'Notes and 

 Queries ' of last month's Geologist, you state, ' We knew of the existence some 

 years since of a Kent Natunxl History Society, the collection belonging to which 

 was formerly at Maidstone, and part is stiil, 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, I 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 which was afterwards sent to the 

 Dover Museum, and no remnant of it now remains in Maidstone. As to the 

 Society, I am sorry we could never muster strength enouiih to form one, but 

 hope ere long, through the really invigorating elfects 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?i 

 M'Kenzie Dick, 52 Poland Street, Oxford Street." 



Plan for Conducting a Geological Class. — " Sir, — If you, thi-ough the 

 medium of your excelleutmagazine, 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 instruction 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. 



CoNTOETED FossiLS FROM Upper Bala Rock. — " Dear 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-
