478 Jtoyal Geological Society of Cornwall. 



British and foreign, from John Edward Lee, Esq., corresponding 

 member of tlie society ; a collection of shells from the tertiary forma- 

 tions on the skirts of the Alps from the Chevalier Michelotti, of 

 Turin ; and a series of rock specimens and organic remains from 

 Pembrokeshire from Henry MacLauchlan, Esq., F.G.S., which af- 

 fords an instructive and admirable illustration of that region, and 

 shows the intimate connection between it and the fossiliferous rocks 

 of Cornwall. 



" The library has been enriched by the Transactions of the Ame- 

 rican Philosophical Society from its commencement, obtained in 

 exchange for a set of the Society's Transactions ; and by the pur- 

 chase of Goldfuss, Deshayes, and Brongniart's admirable works on 

 fossil geology. 



" The Council have therefore great pleasure in congratulating the 

 Society on the flourishing state of its collections. As a large pro- 

 portion of them are deposited in drawers, they consider that addi- 

 tional space ought, if possible, to be obtained for their display, and 

 in order to render them more generally available and useful. In 

 consequence of this augmented and rapidly increasing value of the 

 Society's property, they advise that, for the future, it should be in- 

 sured in the sum of 1000^. instead of 400?. as heretofore. 



" The establishment of an Academy for instruction in the collateral 

 branches of the Science of Mining is an object which has occupied 

 the attention of the Society from its foundation, and its necessity 

 and importance have been often the theme of its reports. The Coun- 

 cil congratulate the Society on the accomplishment of this most use- 

 ful and desirable object by the munificence of Sir Charles Lemon, 

 Bart., and on the ability and reputation of the gentlemen who have 

 been selected to carry it into operation. Its establishment is, how- 

 ever, too recent to admit of an opinion as to its adaptation to the 

 wants of our labouring population : still the Society cannot allow 

 the completion of one of the earliest wishes of its founders to pass 

 without an expression of their most ardent hopes for its success."
