ROYAL GEOLOGICAL SOCIETY OF CORNWALL. 



The ninth anniversary of this Society was held at Penzance 

 on the 1 1 th of October. The Report of the Council states 

 that the progress of the Institution is encouraging; and re- 

 grets the loss of the late Secretary, Dr. Forbes, who has re- 

 moved from the county. 



The cabinets have been enriched by many valuable dona- 

 tions ; and in particular by a splendid series of minerals from 

 Mount Vesuvius, for which the Society is indebted to Sir Hum- 

 phry Davy. The collection of specimens in most of the de- 

 partments of mineralogy is now become interesting, and, being 

 open to public inspection, creates a growing attention to the 

 subject, and has led to the discovery of minerals hitherto un- 

 known in this county. Invitations to correspondence have 

 been received from foreign institutions and men of science; 

 which shows that this Society has already attracted notice 

 both at home and abroad. 



In the publication of the second volume of Transactions 

 it was judged proper to confine its contents entirely to papers 

 relative to the geology and mineralogy of Cornwall ; although 

 it occasioned the regret of thereby omitting many valuable 

 communications. A large space will be found devoted to the 

 detail of numerous facts and experiments on the much con- 

 troverted subject, the Temperature of Mines, and also on the 

 Phaenomena of Veins, which cannot fail to attract much atten- 

 tion and further investigation. 



Since the last anniversary a Course of Lectures on the 

 elements of chemistry has been delivered by the Secretarj', 

 Dr. Boase, to a numerous and attentive auditory, and received 

 with much approbation. And the Council have also the plea- 

 sure to report, that there is evidently a growing attention to 

 scientific pursuits, which encourages them to hope that the 

 period is not distant, when the great object of this Society will 

 be realised by the establishment of a School of Mines in Corn- 

 wall.
