BOTANICAL INFORMATION. 
JBotanical Society in Edinburgh. With much pleasure we insert the follow- 
ing notice of the commencement of a Botanical Society in Edinburgh, a district 
whose Flora is rich, and whose botanists are able. The names of the individuals 
who have been placed at its head are guarantee for the principles upon which it 
is proposed to be conducted, and we trust that this institution will ere long as- 
sume an important part in the science of Scotland. " We rejoice to observe that 
a Botanical Society has been established in Edinburgh. At a meeting which 
was held on the 17th of March, the Society was constituted under the title of 
the " Botanical Society of Edinburgh." The meetings to be held on the second 
Thursday of every month from November to July, inclusive. 
Professor Graham has been elected President, and Drs Greville and Balfour 
Vice-Presidents of the Society for the present year. 
The advancement of botanical science is the object of the Society. Its ope- 
rations will for sometime be confined principally to the holding of periodical 
meetings, to correspondence, to the formation of an Herbarium, and the inter- 
change 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 botanists 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 bene- 
fits resulting to science, as well as individuals, by this arrangement, will, it is 
hoped, be considerable ; especially in regard to the Geographical Distribution of 
Plants in the British Islands, and in the formation of Local Floras. The Socie- 
ty, besides, contemplates an extension 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-Re- 
sident, 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 duplicates. To become a 
Foreign Member, it is necessary to transmit 500 specimens, including at least 
100 species, or a botanical work of which the candidate is the author, the for- 
mer alternative only entitling him to a share of the Society's duplicates. To 
continue to participate in these duplicates, he mu^t afterwards contribute an- 
nually 300 specimens, including at least 50 species. 
The Flora of Edinburgh, which is particularly rich, will afford a constant sup- 
ply of valuable duplicates, and others will be regularly obtained from other parts 
of Scotland, especially the rarer Alpine species. 
Local Secretaries will be appointed in different parts of the kingdom. In the 
meantime all communications are to be addressed (postage paid) to the Secre- 
tary, W. H. Campbell, Esq. 21, Society, Brown Square, Edinburgh."
