and morphology of Marchantia. The metamorphoses of plants are 

 elucidated by Dr. Giraud in the case of a variety of Antirrhinum ma^ 

 jus, and by Mr. Leefe in the transformation of the pistil of Salix 

 caprtea. 



Besides these there are various interesting communications, parti- 

 cularly by Mr. Shuttleworth, on the Diatomacece, and by Mr. Brown 

 of Thun, on Gentiana amarella and germunicu. 



The third part of these Transactions is in progress, and we have 

 reason to believe will be published in the autumn of the present year. 

 From an excellent regulation of the Society (which now consists of 

 about 400 members), those members who may desire to obtain an 

 early perusal of the papers selected for publication, may obtain the 

 sheets by post, as soon as printed, by making a small deposit of money 

 in the hands of the treasurer, to meet the necessary expenses in- 

 curred by affording them this advantage. Accordingly we have be- 

 fore us a portion of the third part, and -can assure our readers that 

 the forthcoming part bids fair to be fully equal to those which have 

 preceded it. 



In conclusion we must congratulate the Society upon so auspi- 

 cious a commencement, and feel satisfied that by continuing the pub- 

 lication of its Transactions with similar spirit, not only will credit 

 be conferred on the Society, but also a decided benefit will accrue 

 to botanical science.
