writer proceeded to demonstrate how very nearly the inhabitants 

 of Cornwall, and especially the proprietors of land, are interested 

 in the prosecution of the study of geology ; and, on these grounds, 

 he demanded of them, as their own peculiar affair, to continue 

 to this Society, and eyery other having similar objects, that pa- 

 tronage and protection which they have so liberally extended 

 hitlierto ; and he appealed to those Cornishmen who were distin- 

 guished for their learniuii; and science (and there are many such) 

 to consecrate some portion of their immortal labours to the wel- 

 fare and renown of their native county. The discourse thus con- 

 cluded : " Stimulated by motives so powerful as the fair fame of 

 our country, the diffusion of useful knowledge, and the increas- 

 ing prosperity of tiie community at large, much may be expect- 

 ed, and we should not forget that much is expected — from the 

 matured labours of this Institution. Let it not then be forgotten 

 that success is the prize of exertion — not of the few, but by a ge- 

 neral concurrence in the spirit of our comprehensive Coinish 

 motto " One and All." Then will the memorial of these our 

 days go down to posterity adorned with the imperishable trophies 

 of Science. But if we supinely neglect the auspicious opportu- 

 nity, instead of living in the grateful recollection of future times, 

 posterity will mourn over our apathy, over the unimproved ta- 

 lents thus buried, 



"And heap the pile with each inglorious name. 

 On the fall'ii altar of their country's fame." 



At this meeting, beaig the first general one since the accession 

 of his present Majesty to the throne, an addres«! of congratula- 

 tion was voted to the King as Patron of the Society.
