Miscellanies. 181 



development takes place in the same manner. Of the remaining top- 

 ics in vegetable physiology, by far the most interesting is the account 

 of the discoveries of Prof. Schultz of Berlin, relative to the two kinds 

 of circulation in plants which he terms rotation and cyclosis. Prof. 

 Schultz communicated his discoveries to the Academy of Sciences at 

 Paris, which in the year 1833 awarded to him the great Montyon 

 prize, and undertook the publication of the memoir and an extensive 

 and beautiful suits A drawings. Dr. Lindley's account is compiled 

 chiefly from the abstract given in the Comptes Rendus ; the memoir 

 itself having only appeared during the last summer. Having had the 

 good fortune to obtain a copy of this memoir we may perhaps give 

 an abstract cf its contents in a future number of this Journal. 



Those whose knowledge of the language will enable them to con- 

 sult the German works on vegetable anatomy and physiology, will 

 find numerous interesting papers and memoirs, as well as several sys-. 

 tematic treatises of the highest merit. Of the latter, the three fol- 

 lowing are the most important : 



13. Meyen : Neues System der Planzen-Physiologie. (New Sys- 

 tem of Vegetable Physiology.) Berlin, 1837-39, 3 vols. 8vo. — 

 The Phytotomie of the same author is an earlier and smaller work, 

 (1830,) in a single volume, with a thin 4to atlas of plates. 



14. Treviranus {Lud. Christ.) : Physiologic der Gewdchse. Bonn, 

 1835-38, 2 vols. 8vo. 



15. LinJc : Grundlehren der Krduterkunde, or Elementa Philoso- 

 phicB Botanicce ; ed. 2. Berlin, 1837, 2 vols. 8vo. — The work, al- 

 though it has a double title-page, is, unlike the former edition, wholly 

 written in the German language. Under the title of Anatomisch-bo- 

 tanische AhUldungen zur Erlduterung der Grundlehren der Krdu- 

 terkunde, Prof. Link has published three fasciculi of illustrations, 

 with descriptive letter-press, each comprising eight large folio litho- 

 graphic plates, filled with highly magnified and very beautiful anatom- 

 ical dissections ; and, at the age of about eighty-three, the still active 

 author is publishing a continuation of the work, under the title of 

 Ausgewdhlte Anatomisch-botanische Abbildungen, of which the first 

 fasciculus has just appeared. The work is published at three Prus- 

 sian thalers for each fasciculus.
