358 Analysis of Scientific Books and Memoirs. 



South America from 24° south latitude, to the equator, and under the 

 line from Para to the eastern frontier of Peru. An immense store of in- 

 formation has been acquired, and very extensive collections in every de- 

 partment of natural history made, all which have safely reached Munich, 

 and are deposited in a noble building expressly fitted for them, called the 

 Brazilian Museum, and of which Spi.v and Martins themselves have the 

 direction. 



Nor are these treasures to remain there unemployed. Drs Martius and 

 Spix are engaged with the noble work on Palms, above alluded to, in 

 which above ninety species will be represented and described on an Atlas 

 folio paper ; and Dr Martius, in conjunction with Dr Zuccarini on the 

 " Nova Genera et Species Plant." of which we possess four Fasciculi, in 

 large 4to, with coloured plates : some of the early ones representing several 

 species of that beautiful and curious genus Vallosia- Separate monographs 

 will be given of the genera Melusloma, Rhexiu, and Eriocaulon. A " Pro- 

 dromus Flora Brasiliensis" is likewise in a state of forwardness, in which 

 will be included every species of plant that is known to be a native of the 

 country, and the whole will be arranged according to the natural orders. 

 The Lichens will be described by Dr Esclnveiler (already known as the 

 author of a new arrangement of this family, and a Monograph of the Genus 

 Rhizomorpha ;) and among them the Graphidece and Trypthclice will form 

 prominent features ; whilst to Dr Homschuch of Griefswald is committed 

 the publication of the Mosses. 



The hall of the Academy of Munich contains the Herbarium of Schreber, 

 which occupies two spacious rooms, and for extent is compared to that of 

 Willdenow at Berlin. The royal library, containing a vast collection of 

 books in every department of botany, is open every day for the use of the 

 public. 



The venerable Dr Hoppe gives an interest to the town of Ratisbon. 

 This excellent man is indefatigable in exploring the botanical treasures of 

 the Alps in the south of Germany and we have given very full and inte- 

 resting extracts from him and Homschuch' s " botanical Travels in Carniola" 

 &c. in the earlier volumes of our journal. Ratisbon, too, has a Royal 

 Botanical Society. At Gefrees, near Bayreuth, resides M. Punch; an apo- 

 thecary, who has published the beautiful " Moss Pocket-book." 



Anspach seems to have no botanist to replace Gleichen and Schmidel. 

 Bonne upon the Rhine possesses one of the most eminent and most inde- 

 fatigable of the German botanists, and one from whose correspondence and 

 communications we have experienced both pleasure and instruction, Dr C. 

 G. Nees von Esenbeck. His " System of Fungi" in 1 vol. 4to, with nu- 

 merous and beautiful plates; his " Handbuch dcr Botanik ;" his various 

 memoirs in the " Bolanische Zeitung ;" " Horw Physicw Berolinenses'' 

 " Nova Acta Acad. Cres. Leopold ;" his translation of all the works of our 

 Brown, together with his notes appended to them, will alone suffice to 

 point him out as a man of deep research, well- versed in every department 

 both of practical and theoretical botany, and possessed of the most gentle- 

 manly mind and feelings. His brother, Dr Th. Ft. von Esenbeck junior
