 of Mr. B4KtwKLL's Lectnres, as to his Originality tn 

 exiiihitins, a Geol»i>ical Map of England : until Remarks

 Strata anywhere else appear in England P ; IVere Caverns 

 formed by siilterranean Currents of IFater P ; and, How 

 were Mineral Veins opened and filled ?. By Mr. JoHN 

 Fabev Senior. 



To Mr. Tiiloch. 



Sir, When I first read in your account of Mr. Robert 

 Bakewell's Lectures, at the Russell Institution, p. 234, of 

 your March Macazine, that Mr. B. exhibited to his auditors, 

 " a Geological Map of England, drawn for the purpose" of 

 his Lecture's, and said, '• that, so far as he knew, /Am was 

 thefrst attempt to represent in a Map the geological out- 

 lines of En^rland," I supposed this statement, of a claim 

 to originaruy in ininera! Maps of England, to be made, by 

 an error or misconception of your Reporter, and which from 

 its manifest injustice to others, would receive a speedy cor- 

 rection from Mr. Bakewcll, or some of those who attended 

 his Lectures: after waiting, however, the conclusion of his 

 three courses, without seeuig anything further on the sub- 

 ject, I am induced to request your permission to point out, 

 that it i^ incredible that Mr. B. should have been unin- 

 formed, that Mr. IVilUam Smith of Buckingham street, 

 had nearly completed such a Map years ago, as very often 

 has been mentioned in your Magazine*, in Dr. Rees's Cy- 

 clopsedia, &c.; not to mention a work, to which Mr. B. 

 himself refers (at p. 236), my Derbyshire Report, vol. i. 

 p. 108; nor is it more likely, that Mr. B. was uninformed, 

 ihat a primary object of the Geological Society ot Loudon, 

 as expressed in tWeir printed " Geological Inquiries," was to 

 prepare " Mineral Maps of districts"," or that he was alto- 

 gether ignorant of the progress, that G. B. Grecnough, 

 Esq. their very able and indefatigable president had made, 

 in a Map of England and Wales, and another of Scotland, 

 which have been very liberally shown (as his important 

 collection corresponding to them has) to great numbers, 

 besides the members of the Society assembled at their 

 nieeiinys ; which last Maps, from combining, all that had 

 been learnt from Mr. Smith, either directly or through me, 

 or others who have examined his Maps and collection, with
