 coal, and diffusion of gravel and sand in the sea ; Consolidation 

 and hardening of rocks ; Mineral veins ; Mosaic geology, as 

 explained by Mr. Penn; Bones and shells in rocks and 

 caverns, and in the soil ; The great rock basins of London, 

 Paris, and the Isle of Wight, with the extinct animals of a

It may be objected to these Conversations on Geology, that 

 they contain too many objections, and leave many parts of the 

 subject in utter uncertainty : but we may be permitted to reply 

 to this, that all the systems of geology are precisely in the 

 state in which they are here represented, uncertain and imper- 

 fect in their theories and speculations ; though these are gene- 

 rally illustrated by interesting and well ascertained facts, and 

 sufficiently plausible arguments. The author of the Conver- 

 sations, therefore, it would appear to us, has acted judiciously 

 in representing the actual imperfections of geology, rather 

 than concealing them, and in expressing doubts upon points 

 imperfectly ascertained, rather than dogmatising.
