382 Prof. Meyen's Report of the Progress of 



creased in number, but the results of the labours recorded in 

 them continue to become from year to year greater and more 

 important. Systematic botany has received in the year which 

 is past numerous and valuable contributions, for a whole series 

 of most important works have appeared, not only on Phanero- 

 gamia, but also on Cryptogamia ; vegetable physiology, also, 

 has been enriched by a great amount of new data, and more 

 correct views have been diffused in numerous publications upon 

 many subjects, respecting which less accurate notions had 

 heretofore been entertained. Nay, the number of works which 

 appeared last year on subjects of physiological botany is so 

 great that it is impossible in the small space allowed us to go 

 fully into their contents, and it is more especially difficult to 

 accomplish this with respect to the rich contents of some of 

 the manuals which have appeared. 



Several subjects of vegetable physiology which have been 

 very fully treated of in former reports must also be now again 

 noticed with greater minuteness : this perhaps might seem 

 superfluous, but the object aimed at by the writer in these 

 elaborate reports is to produce an unity in the views and an 

 accordance in the observations and doctrines relative to the 

 structure and functions of vegetables ; so that this science may 

 in the end become worthy to take its place by the side of ani- 

 mal physiology. 



Great is the loss which the circle of botanists has sustained 

 during the year which has terminated : Schrank, Persoon, 

 Jussieu, and Schrader are no longer among them. Their la- 

 bours are known, and will long impart lustre to the history of 

 our science. 



Since the first publication of this work ( Wiegmann's Archiv) 

 several yearly reports have appeared in Germany and in 

 France, the contents of which more or less resemble ours. 

 From the geographical position of Sweden, Wickstrom's year's 

 report on the progress of botany must always reach us very 

 late, and can never be so complete as if it had been prepared 

 in the interior of the Continent; in order to remedy this de- 

 fect Beilschmied has undertaken to translate those reports into 

 German, and at the same time to enrich them with the most 

 recent literature in which they are deficient. Thus last year 

 we received Wickstrom's report for 1834?*. A second volume 

 of the Archives des Decouvertes et Inventions nouvelles faites 

 dans les Sciences, les Arts et les Manufactures tant en France 

 que dans les Pays th -angers pendant Vannee 1835f has ap-
