562 Br. Gilly in Reply to Mr. Farcy 



in my last paper could not fail to excite tlie irritability of so 

 pugnacious a polemic as Mr.Farey, and in that case I resolved to 

 forbear from any rej>ly; and, to use a childish phrase, to allow 

 bim the last blow. But upon reading this reply, I find it so full 

 of misrepresentation, and to contain so many perversions of my 

 meaning, that 1 cannot forbear noticing them. 



First, then, I have not made any use in my last paper of Pro- 

 fessor Jameson's name, in order to appropriate to myself the dis- 

 covery of the unconformable position of the red ground, as Mr. 

 F. has falsely asserted top of p. 279- — My words arc, " But any 

 thing 1 can say will be of far less consequence than the opinion 

 of Professor Jameson, who allows me to state, that as far as he 

 can judge from the description I have given, and the s])ecimens 

 1 have shown bin), he considers the red sandstone and mountain 

 limestone as members of the first floetz formation." 



1 do not unhandsomely charge Mr. Farey with wishing to in- 

 troduce confusion as to the geology of England ; for I say no- 

 thing more than is warrantable from the flagrant geological 

 errors which Mr, F. lias coannitted. One of the most prepos- 

 terous is that of referring the sienite of Leicestershire to that 

 cmnigeHnim formation, the red ground, — contrary, I venture to 

 sav, to the opinion of every sensible geologist in Britain ; and 

 contrary to the facts so beautifully displayed by the stratification 

 on the western side of the Rialvern range. This rar.ge, I need 

 not repeat, consists in great measure of a sienite, which even 

 Mr. Farev, as he wishes to imbed it in the red ground, cannot 

 but allo'.v to have been formed at the same time with the sienite 

 of Leicestershire. The fact to which I allude I have men- 

 tioned p. 186 and ISS of my paper, but I beg leave once more 

 to press them upon Mr. Farcy's notice. Upon the west side of 

 the range there rests a formation of limestone, which Dr. Pri- 

 chard in the Annals of Philosophy assures us is seen dipping 

 THider the red sandstone of Herefordshire. This red sandstone, 

 as I have mvself ascertained in comj)any with Dr. Prichard, lies 

 below the mountain limestone ; so that we have these rocks 

 formed, besides a world of coal beds and coal measures, before the 

 red ground, which is supposed to be a twin production with the 

 sienite, was deposited. All these facts, however, will, I daresay, 

 l)e of little avail in altering Mr. Farcy's opinion j and I unfor-r 

 tunate 



" Noil profcctnris littora bobiis aro." 



Another of these extravagancies, by which Mr. Farey outrages 

 every thing like system, is to be found at p. 280 of his Report, 

 where he gives it as his opinion, without the shadow of a proof 

 in su])port of that ojjinion, " that the Aih limestone of Derby- 

 shire is the lowest which is any where seen in England^ not ex- 

 cepting
