S76 Royal Geological Society of Cornwall, 



mens of the rocks in the different districts, with a view of placing in 

 the Museum a complete series of Cornish Geology. 



Within the last week, a proposal has been made to the Society by 

 Mr. Thomas, who some years ago published a map of one of the 

 principal mining districts in Cornwall. He has since surveyed other 

 parts of the county, and is still proceeding in the work. He offers to 

 the Society the result of his labours and observations, as he may com- 

 plete them, on condition that the Society will undertake their publi- 

 cation, and allow him one half of the profit. This proposal has been 

 so recently made, that the Council have not been able to pay any at- 

 tention to it ; but they recommend it to their successors to ascertain, 

 in the first place, whether Mr. Thomas's labours include every thing 

 which ought to be comprised in a geological map, and secondly, 

 whether it is likely that the sale would defray the expense of publi- 

 cation. The profit, if any, should wholly belong to the meritorious 

 individual who has thus devoted his time and abilities to the comple- 

 tion of such a desirable object. But whatever may be the result of 

 this proposal, it ought not to interfere, in the smallest degree, with 

 the mode already proposed, of proceeding with the geological map 

 of Cornwall. 



The Cabinet of the Society, which annually increases in interest 

 and importance, has, in the present year, been enriched by various 

 donations and purchases of minerals. At the last annual meeting, the 

 Council had particularly to notice an extensive collection of speci- 

 mens presented to the Society by Dr. John Davy : they have now 

 the pleasure to mention another donation from the same gentleman, 

 the particulars of which, as well as of the other donations, will be 

 found in the Curator's Report *. 



It was announced at the last annual meeting that arrangements 

 were in progress for the removal of the Penzance library to a larger 

 building, and that, in consequence, the room occupied by that Insti- 

 tution would be added to the Museum ; of this room the Society will 

 take possession about Christmas next : and it is intended to appro- 

 priate it entirely to the geological collection, leaving the present 

 apartment for the mineralogical collection, which will even now 

 occupy the greatest part of it. 



As the copies of the laws of the Society have been long since ex- 

 hausted, the Council recommend their revision and republication. 



By order, 

 October 10th, 1828. Edward C. Giddy, Secretary. 



The following papers have been read since the last Report : — Some 



* Dr. Davy's donation consists of the following articles : Specimens of 

 malachite, native mercury, cinnabar, phosphate of lead, augite, rock- 

 crystal, Egeran (from Eger,) Epidote, green felspar, Hauyne, leucite, 

 Wollastonite, Fassaitc, Sahlite, &c. &c. from various parts of Asia Minor, 

 the Ionian Islands, &c. Also specimens of ancient coins, of which the 

 metals appear to have been decomposed and mineralized ; and specimens 

 of lead, iron, bronze and glass, found in ancient tombs in Greece and the 

 Ionian Islands.
