Its operations will, for some time, be confined principally to 

 the holding of periodical meetings, to correspondence, to the 

 formation of a herbarium, and the interchange of specimens. 

 The last is a new feature in the constitution of such a society, 

 and will be conducted by a committee, in accordance with 

 certain rules embodied in the laws. The desiderata of bo- 

 tanists in all parts of the kingdom will be supplied, as far as 

 possible, from the Society's duplicates ; and individuals will 

 secure the important advantage of exchanging the botanical 

 productions of their respective districts for those of others 

 more remotely situated. The benefits resulting to science, as 

 well as to individuals, by this arrangement, will, it is hoped, 

 be considerable ; especially in regard to the geographical 

 distribution of plants in the British Islands, and the formation 

 of local floras. The Society, besides, contemplates an exten- 

 sion of this plan, by promoting an exchange of specimens with 

 botanists in other parts of the world. The members will be 

 divided into the following classes : — resident, non-resident, 

 foreign, and associate. Any person wishing to become a 

 non-resident member must be recommended by two individuals 

 belonging to some scientific or literary society, and pay a 

 contribution of two guineas ; which, without any additional 

 payment, will entitle him, as long as he continues annually to 

 send specimens to the Society, to a participation in the dupli- 

 cates. To become a foreign member, it is necessary to trans- 

 mit 500 specimens, including at least 100 species ; or a 

 botanical work of which the candidate is himself the author; 

 the former alternative, only, entitling him to a share of the 

 Society's duplicates. To continue to participate in these 

 duplicates, he must afterwards contribute annually 300 spe- 

 cimens, including at least fifty species. The flora of Edin- 

 burgh, which is particularly rich, will afford a constant supply 

 of valuable duplicates; and others will be regularly obtained 

 from other parts of Scotland, especially the rarer alpine spe- 

 cies. Local secretaries will be appointed in different parts of 

 the kingdom. In the meantime, all communications are to 

 be addressed (postage paid) to the secretary, W. H. Camp- 

 bell, Esq, 21. Society, Brown Square, Edinburgh. — M.
