Specimens were stated by the Secretary to have been received 

 since last meeting, from the Rev. Mr Gordon, Dr Walker Arnott, 

 Mr Shuttleworth, Professor Meisner, Mons. Guthnick, and Colonel 

 Brown. Donations to the library were presented from R. J. Shut- 

 tleworth, Esq. and Professor Meisner. 



Dr Balfour read a communication, addressed to the President of 

 the Society, from the Rev. Gerard Smith of Chichester, accompany- 

 ing specimens of I.ycopodium pallescens, and explaining the proper- 

 ty which it possesses, in common with several other species of the 

 same genus, of expansion in water, and of recollapsing when dried, 

 subsequent to immersion ; a power which it retains for many years, 

 if not too long exposed to moisture, in which case the spikelets rot, 

 and fall off upon drying. Specimens were exhibited in different 

 states ; some which had been immersed and were fully expanded ; 

 others in the act of expansion ; and others again, in the dried and 

 collapsed state. 



A remarkable variety of Lamhim purpurenm, from Dr Greville's 

 herbarium, was exhibited, which, from its deeply incised leaves and 

 general appearance, approached very near to L. incisum. A beautiful 

 series of drawings prepared by Dr Greville for the Algai Britannicce 

 were also laid before the society, and attracted much interest. 



March 9th. — Professor Graham in the chair. The following 

 members were elected : Resident, Mr Henry Mapleton, Mr William 

 Walker. Non-resident, Mr George J. Lyon, Glasgow ; Mr James 

 Stuart Menteath, yr. of Closeburn ; Dr G. A. F. Wilks, London. 



Specimens were presented from Mr M. J. F. Sidney. 



Dr Graham read a letter from the Countess of Dalhousie, inti- 

 mating her intention of presenting to the society her East Indian 

 Herbarium ; and at the same time exhibited one of the fasciculi of 

 this most valuable collection, as illustrative of the admirable manner 

 in which the specimens had been prepared and preserved. The 

 thanks of the society were unanimously and warmly expressed to 

 Lady Dalhousie for her splendid donation ; and the proposal, that 

 her Ladyship should be elected an honorary member, having met with 

 the most cordial approbation, it was carried by acclamation.
