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 suite of 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 ebtain a copy of this memoir we may perhaps give 
an abstract of its contents‘ia 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. Svo.— 
The Phytotomie of the same author is an earlier and smaller work, 
(1830,) in a single ee with a thin 4to atlas of plates. 
14. -engemane (Coa Christ.): ite oie der Gewachse. Bonn, 
1835-38, 2 vo 
15. Link: Grundlehren der Kréuterkunde, or Elementa Philoso- 
phie Botanice ; 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 ischabe 
tanische Ab bildungen zur Erliuterung der op UFa darn Or ae 
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 
Ausgewdhlie Anatomisch-botanische Abbildungen, of which the first 
fasciculus has just appeared. The work is published at three Prus- 
sian thalers for each fasciculus.
