458 Proceedings of Philosophical Societies, [Dec. 



of a national reproach has been thereby postponed ; but they 

 will not yet despair of the eventual accomplishment of a mea- 

 sure, first suggested by this Institution, and which it has never 

 ceased to recommend. This Society, enrolhng amongst its 

 members a great portion of the rank and wealth of the county, 

 should be foremost in promoting an Institution of the first im- 

 portance, both in an economical and scientific point of view ; ' 

 and for the establishment of which " one and aW should unite, 

 who are interested in the honour and prosperity of Cornwall. 



The Museum, which in the foremost place commands the 

 CounciFs attention, has been enlarged by the addition of 

 another Cabinet extending the whole length of one of the 

 galleries : this has afforded sufficient space for the exhibition of 

 several series of Foreign specimens, which have been arranged 

 by the Curator with his usual neatness and judgment. The 

 attainment of this object will afford but little interest to the 

 scientific stranger ; but to our native students it is of great im- 

 portance, as displaying examples of the various and dissimilar 

 mineral productions of our globe. To our constant and liberal 

 correspondent William Maclure, Esq. of Philadelphia, we are 

 indebted for another donation of minerals from the United 

 States of America ; consisting of various modifications of Ser- 

 pentine, of Augite, Maclurite, Franklinite, Red Oxide of Zinc, 

 and other interesting specimens. Doctor Jer. Van Rensselaer, 

 of New York, has presented to the Society several earthy and 

 metallic minerals, which are particularly specified in the Cura- 

 tor's Report of donations. 



Captain Wallis, of Bodmin, has also presented a series of 

 specimens illustrative of the geology of the country between 

 Hydrabad and Madras, accompanied by a descriptive account 

 of the same, together with a map of this part of the penin- 

 sula of India. 



To the kind contributions of several members, in compliance 

 with the request made at the last annual meeting, the geological 

 department has .been recently indebted for many specimens of 

 granite ; but the varieties of this interesting formation are so 

 numerous, that many more would be equally acceptable. 



The department of simple minerals has also been enriched 

 by the purchase in Cumberland of a series of splendid minerals, 

 consisting of variously crystallized galena, blende, fluor spar, 

 sulphate of barytes, arragonite, and other substances. 



jBefore concluding, the Council take this opportunity of so- 

 liciting further donations from those members who have private 

 collections : many may have refrained from presenting their spare 

 duplicates on the ground that our Museum already possesses 

 better specimens of the same kind : these however would be 

 very acceptable, and would enable the Society to comply with 

 the repeated applications that have been made by institutions, 

 both at home and abroad, for an exchange of minerals.
