Walmstedt for Prehnite, except that it contains no water. The 

 Jacksonite, dried at 100° C, was found to contain less than -^^ 

 per cent, of water. The ratio of the oxygen in this mineral is 

 an unusual one, and had led Berzelius to adopt another formula 

 for Prehnite. 



Dr. Cabot announced the donation from Mr. James Rich- 

 ards, of a fine specimen of the Wandering Albatross, Diome- 

 dea exulans, Lin. 



Mr. Sharp presented a Seed-vessel of Nelumbium luteum. 



Messrs. Junius Hall and Horatio Bigelow were elected 

 members of the Society. 



Dr. Storer offered the following resolutions, which were 

 unanimously passed. 



Resolved, That the heartfelt thanks of this Society be present- 

 ed to those gentlemen whose munificence has enabled us to call 

 this temple our own.* 



Resolved, That we will endeavor to prove our sense of obli- 

 gation by a renewed devotion to the cause of science. 



Resolved, That we deeply feel the kindness and liberality of 

 George M. Dexter and Edward C. Cabot, Esqrs. in advising and 

 aiding in the architectural arrangements of our building ; and 

 most especially do we feel indebted to N. B. Shurtleff, M. D., for 

 the skill he has exhibited in adapting, and the zeal and fidelity 

 with which he has for months superintended the advancing work. 



Dr. Storer remarked, that there were many individuals whom 

 it would be grateful to his feelings to thank, by name, for the aid 

 they had rendered in money and labor in the accomplishment of 

 the work. But, as he could not name some and omit others, 

 without injustice, he forbore. There was, however, one individ- 

 ual, whose services had been so efficient, that it might truly be 

 said that without him the enterprise could not have been accom- 

 plished. He meant the President of the Society. He was sure 

 that every member must feel how deep was our obligation to 

 that gentleman. 



The Secretary offered the following resolution, which 

 was adopted. 



* The sum of $28,660 was contributed for this purpose, mostly by the persons 

 whose names have been given on the first page, as Patrons of the Society.
