LINNEAN SOCIETY OF LONDON. 29 



colleague ou the termination of tlieir great and invaluable work, 

 of wliicli it would be impossible to speak too highly. The first 

 part was published in 1862. The number of genera included are 

 about 8000, containing about 100,000 species ; but Mr. Jackson, 

 who has gone carefully over the whole work, informs me that 

 more than 26,000 genera are mentioned, the great majority oi 

 which are ranked as synonyms. 



In conclusion I must express my thanks to the Fellows, and 

 especially to the Council and Officers, for their support during 

 the past year. I am well aware of my deficiencies as President, 

 especially in comparison with my eminent predecessors. 



Report on tlie Chief Botanical Fublications issued during the 

 twelve months from May 1882 to April 1883. Prepared for 

 the Anniversary of the Linnean Society. 



At the last Anniversary I attempted to lay before you a hasty 

 sketch of the more important Botanical publications which had 

 come under my notice during the previous twelve months. In 

 pursuance of the same object, I have now the honour to submit 

 to you a similar list for the Society's year vi'hich has just closed. 

 I cannot pretend to criticise the majority of the works or papers 

 cited, but must perforce content myself with little more than 

 indicating the productions of the various authors by name. 



Proceeding on the same plan of arrangement as last year, I 

 would mention that Prof. Delpino has again issued his ' Rivista 

 di botanica ' for 1881. Dr. Just's ' Botanischer Jahresbericht ' 

 has been issued with rather greater promptitude than heretofore, 

 to the great gratification of all working botanists. I am not 

 aware if Heeren Bohnenseig and Burck's ' Kepertorium ' has 

 been discontinued ; but I have not seen a copy. Drs. Uhlworm and 

 Beliren's ' Botanisches Centralblatt ' is even more appreciated 

 than before, and has become a most useful publication. Of other 

 bibliographic issues I may name : — the first part of Trautvetter's 

 " lucrementa florse phanerogamica3 Eossicae," in the 'Acta' of the 

 St. Petersburg Botanic Garden ; Dr. Bretschneider's Studies in 

 the early Western researches into Chinese Botany ; M. Deby's 

 Catalogue of Books on Diatomacete ; and the attempts towards a 

 bibliography of Applied Botany issued by tlie Index Society. 



Of Palaeobotanical productions I may allude to Goppert and 

 Menge's ' Flora des Bernsteins,' vol. i. ; Dr. Paul lieinsch's 

 Mici-ophotographs of Coal ; the third volume of Renault's 

 ' Cours de botanique fossile,' comprising the Ferns ; the third 

 part of the first volume of Mr. Gardner and Baron von Ettiugs- 

 hausen's ' British Eocene Flora ;' Prof. Lesquereux, ii.. Contribu- 

 tions to American Geology, contains " Fossil plants of the aurife-
