 all periodicals specially devoted to any branch of our sciences. The 

 Eeports on the contributions to the various branches of zoology in- 

 serted in "W^iegmann's ' Axchiv " under the editorship of, and some 

 of them compiled by, Troschel, replace in some measure the ' Zoolo- 

 gical Record ' for the German public, and are kept up nearly to the 

 same period, some of the reports for IS 70 ha"dng already appeared ; 

 they are also much to be commended, although they may not have 

 quite the method and completeness of the ' Zoological Record.' I 

 have farther to congratulate science in general on the near com- 

 pletion of the Royal Society's great Catalogue of Scientific Papers, 

 the sixth and last volume of "which is far advanced, and likely to be 

 in our hands by the commencement of the next session of the Society. 



In Botany, Pritzel's excellent and much improved second edition of 

 his ' Thesaurus ' is rapidly going through the press, and brings the 

 repertory of separat-e botanical works do"wn to the year 1871. 

 Current botanical publications are also generally noticed in various 

 botanical periodicals, especially : — the ' Giomale Botanico Italiano,'

 perhaps the fullest bibliographical re"n.e"w ; and the ' Journal of 

 Botany,' "which promises "well under the ne"w and active editorship 

 of Dr. Trimen. But, "with the exception of Lichenography, the 

 bibliography of "which is brought do"wn to the year 1870 in Krempel- 

 huber's detailed History and Literature of lichenology, "we have 

 no comprehensive references to Memoirs and Papers published 

 since 1863, the term of the Royal Society's Catalogue, and "we feel 

 much the "want of an annual summarv corresponding to the 

 ' Zoological Record.' 



A "work has recently appeared "which has naturally attracted much 

 of my attention as being intimately connected "with a branch of the 

 science "which I have on several occasions taken as the subject of 

 my annual Addresses, and as being the result of long and careful 

 study of the great and varied mass of data collected by its laborious 

 and distinguished author. I speak of Grisebach's Vegetation of the 

 earth according to its climatological distribution, "with the secondary 

 title of a Sketch of the comparative geography of plants, ' Die 

 Vegetation der Erde nach ihrer klimatischen Anordnung, ein Abriss 

 der vergleichenden Geographie der Pflanzen." The general scope
