NOTICES OF BOOKS. 191 
Prospectus of a periodical publication for ScrENTIFIC Botany and 
ZooLoaY : edited for the Botanical department, by ALEXANDER 
BRAUN, and Cart NAGEL; for the Zoology, by CARL THEODOR 
VON SIEBOLD, and SOLBERT KOLLIKER. 
* The editors intend, by this periodical (of "hih the botanioal part is 
to be considered a continuation of that for Scientific Botany by M. 
J. Schleiden and Carl Nägeli), to excite a closer and more acknowledged 
cooperation in inquiries into the laws of organic life, by concentrating 
exclusively, into one publication, the many scientific labours of this 
nature, which are scattered about and mixed up with NODE 
matters in many works. 
To effect this object the editors consider it important to bémbine 
both botanical and zoological researches; because in this manner only 
ean the common as well as the peculiar dani of animal and vege- 
table organization and functions become properly understood, and the 
true line of demarcation between the two kingdoms be defined. "They 
desire to give their undertaking the highest possible character of 
science, and exclude, therefore, all accounts of new genera or species 
not absolutely conducive towards the main object defined above; as also 
all notices of simply natural-historical purport, or horticultural, medi- 
cinal, &c., unless they contain matter relating to, or throwing light 
upon, points of anatomy or physiology, especially morphology, compa- 
rative anatomy and histology. Thus also all literary events elucidat- 
ing these topics will be duly noticed; but simple announcements 
of books, or extracts, or reviews, are beyond the object of the present 
underta 
With pim to this exposé, the editors solicit contributions, and 
promise speedy and correct publication with plates wherever required. 
'The publisher, Mr. William Engelmann, announces that two volumes 
are to appear annually, in four numbers; one volume of botany, the 
other zoology, each of about twenty-five sheets, and twelve neat litho- 
graphic plates. Price for both, 6 rthlr. (£1). To be had also separately, 
each volume for 34 rthlr.—(N. W.)
