L 2Go Observations on Dr. Richardson's Taper respecting 



Smith, Dr. Richardson, M. Andre, &c, may engage in 

 extended and minute inquiries, as to <c the actual surface of 

 the earth," (p 1 70 of the present volume,) without which 

 direction to their inquiries, the mention or" geology must 

 continue to be received with a smile, as M. Cuvier and his 

 very able associates justly remark. 



In order to show that hummocks or isolated caps of strata 

 are not confined to basalt, or any other stratum in particu- 

 lar, but are of common occurrence irr denudated districts, I 

 beg to present the following list of a few which I have ob- 

 served, and noted most of them, in the part of my geological 

 map of Derbyshire, a copy of which has been now some 

 time in possession of my worthy patron in these pursuits, the 

 President of the Royal Society, referring for some furtherpar- 

 ticulars, to my Section plate II. of your thirty-first volume.
