7. The Archiv fiir Naturgeschichte, established and for the last six 
years conducted by the late Prof. Wiegmann of Berlin, is to be contin- 
ued, as we learn from a late number of the Linnea, by Dr. Erichson, 
assisted by Dr. Grisebach of Gottingen, Prof. Siebold of Erlangen, Dr. 
Troschel of Berlin, Prof. A. Wagner of Munich, and Prof. R. Wagner 
of Gottingen. Annual zoological and botanical reports will still be 
given: the latter, furnished for some years past by the late Professor 
— will hereafter be executed by Prof. Link. 
8. A Repertorium fia Anatomie und Physiologie den Gebebeds 
with annual reports, nearly on the plan of those of the late Prof. Meyen, 
(generally known to English readers, through the translation published 
in the Annals and Magazine of Natural History,) is announced by the 
accomplished vegetable anatomist, Prof. Mohl of Tibingen, in the 
, Linnea; part 8, for 1841. 
9. Lectures on the Applications of Chemistry and Geology to Ag- 
ort ; by James F, W. Jounstron, Professor of Chemistry and 
q in the University of Durham. Part I. On the Organic Ele- 
; eae of Plants. New. York, Wiley & Putnam. 12mo. 1842.—It 
is a just remark, and those whom. it chiefly concerns are beginning to 
appreciate it, “that no department of natural science is incapable of 
yielding instruction, —that scarcely any knowledge is superflvous—to 
the tiller of the soil.” The botanist, the chemist, or the geologist may, 
and indeed | commonly does prosecute his laborious researches from the 
mere loye of his favorite science : whatever personal advantage he may 
perchance, derive, is small indeed, compared with what he might rea- 
». sonably expect from the same industry and talent devoted to other pur- 
suits. But to no class, perhaps, are the results of scientific research 
practically important as to the proprietors and cultivators of the soil ; 
or no art is so connected with all the natural sciences, and so Pteuds 
. ent upon them for its advancement, as agriculture. Would the farmer 
know what vegetables, or what varieties are best adapted to a particular 
climate or soil; which require his richest, and which will thrive upon 
his poorest soils; which exhaust, and which on the contrary may 
made to enrich his land; what treatment is necessary to perpetuate the 
choice varieties, parduerd by long cultivation, but which are continually 
liable to ‘run out,’ that is, to revert to their original state ; how the 
properties of poisonous plants may be ascertained, or noxious weeds 
eradicated ; to these and numerous similar questions botany and vege- 
table physiology must render the only satisfactory answer. If his crops” 
are threatened -with destruction by insects, zoology alone can throw 
light upon their nature and habits, and instruct him how to:
