latter, more particularly of the interior of the mines of Cornwall. 

 Donations have been received from other gentlemen, which will be 

 specified in the list. 



The Coimcil have to regret, that so few communications are 

 made to the Society by the intelligentagentsof mines, many of whom 

 are, from their attainments, their habits of observation, and their 

 opportunities, capable of rendering considerable service to the sci- 

 ence of Geology. The Council cannot help suspecting, that it is 

 a common impression, that no communications are desired, except 

 of rare and extraordinary facts: of these the Society, of course, is 

 always glad to be informed; but they would be particularly glad 

 to receive information of the common, and what may be deemed the 

 every-day facts, which occur in every mine in Cornwall ; by a series of 

 such communications, the distinction might be easily made, between 

 facts which are of universal occurrence, — those which always occur 

 under certain circumstances, — those which occur more rarely, — 

 and those which form exceptions to all known or supposed rules.
