required, which may be obtained by the enlargement of the present 

 rooms, without incurring any considerable expense. 



" It is impossible for a cursory observer to form an idea of the extent 

 of the geological collection ; for several series, and among them Mr. 

 Henwood's specimens of veins and veinstones, exceeding a thousand 

 in number, are deposited in drawers. 



" Since the last Meeting, Dr.Boase's numerous and instructive spe- 

 cimens of Cornish rocks have been labelled and arranged : and the 

 Council have the satisfaction to state, that measures are about to be 

 taken to place the classification of the remaining geological series on 

 the same respectable footing as that on which the mineralogical col- 

 lection stands, through the able and zealous exertions of Mr. Giddy, 

 who, they are sorry to announce, has, through indisposition, been 

 under the necessity of tendering his resignation as Secretary, but has 

 kindly consented to continue his valuable services as Curator." 



(By Order) E. C. Giddy, 



August 30th, 1833. Secretary.
