Vor. VI.J Retrofpee? of German Literature....Giconomy. 
With all its excellenctes, we cannot re- 
commend this book to beginners, as the 
author has committed many ferious inac- 
curacies, while he has little or no merit 
in the moit interefting fection of the work, 
** The metaphyfics of Nature,’ which is 
almoft literally copied from Kant’s own 
words, and which ought to have been 
rendered more eafy to the tyro, by giving 
it a more popular form, and accompany- 
‘ing the many abftrufe axioms and princi- 
ples with proper illuftrations. The next 
aud more important article in this branch, 
is “« The Magazine of the lateft difcoverics 
and occurrences in Natural Philofophy,” in- 
cluding all the auxiliary fciencés con- 
nected with phyfics, by J. H. Vorer, 
No. I. with three plates, 8vo. pp. 182. 
Since the ‘* Magazine for the lateft events 
in Phyfics and Natural Hiftory’? (which 
was firft begun by the celebrated Profeflor 
Lichtenberg, of Gottingen, and after- 
wards continued by Proteffor Voigt) has 
been clofed with the eleventh volume, the 
prefent is intended to fupply its place, 
‘The editor does: not admit long and de- 
tailed eflays, that the numbers of this pe- 
riodical work, the annual amount of which 
ss not determined, may not too rapidly 
inereafe. Hence he has reduced it to the 
more ufefal sorm of a repertory, which is 
divided into three principal feétions; the 
firft contains accounts of new objeéts of 
natural philofophy; the fecond, accounts 
of new or improved phyfical inftruments, 
or apparatus; and the third, a fhort re- 
view of the lateft ate of phyfical litera- 
ture. As a proof of the great variety 
prevailing in this entertaining Magazine, 
we find not lefs than 27 articles under the 
firft head, Upon the whoie, it juftly 
vies with ‘ Gren’s Phyfical ¥ournal,” 
which is univerfally admitted to be the 
molt complete amd {cientific work of the 
kind in Europe; inafmuch as it more 
largely enters into the nature of fubjeéts, 
and gives a more precile account of the 
phenomena of nature than could be done 
with propriety in Mr. Voigt’s new Maga- 
zine, 
@CONOMY. 
{t is much eafier to propofe a new 
theory of -agriculture, and to extol this 
principal fource of wealth and happinefs 
in every nation with extravagant praifes, 
than to point out the general and molt 
hurtful defe&ts here prevailing and to of- 
fer the moft proper and practical means 
for removing and remedying fuch impe- 
diments. With this falutary istention, 
and with a view to avoid the errors into 
which others have fallen, the author of 
the following treatife hus amply fatisfigd 
543 
our expectations: . On Agriculture as the 
principal Source of Wealth and Happinefs 
of Nations,* by W. Kraus, pp: 2365 
8vo. In this elaborate effay, Mr. K. 
cenfures the many defects in agriculture 
with great candour and modefty ; every 
where we difcover mature manly reflec~ 
tion, and his true interett for the good 
of mankind has given a degree of ftrength 
and energy to his language which cannot 
fail to make a favourable impreffion on 
cultivators of land, and thus contribute 
to realize the noble defign of the author. 
Of the “ Economical Contributions towvarde 
the Improvement of Agriculture in Lower 
Saxony ;"" by J. D. Denfo, we lave {een 
the fecond number, which is replete with 
judicious and praétical remarks on four- 
teen different fubje&ts, chiefly founded on 
the author’s own obfervations and expe- 
rience: thofe on different methods of con- 
verting heaths and comnions into arable 
land, are by far the moft valuable '«« The 
Economical Fournal for Town and Coun- 
try,” formerly edited by Profefior LEon- 
HARD1I, of Leipzig, is now continued, 
from the gth volume, by a Mr. Horr- 
MANN, of the fame place; and we are 
happy to fay, that it is conduéted with a 
due fhare of attention and difcrimination 
by the neweditor. To prevent the dread- 
ful devaitations of forefts occafioned by. 
Noxious inteéts, and particularly the ca- 
terpillar, a learned and -noble planter of 
woods has lately begun a periodical pub- 
lication, under the fingular title, *« The 
Anxious Forefler,” by J. C. BARON Vv. 
LINKER, of which we have three numbers 
before us.. The eflays here contained are 
of the utmoft importance to the planter of 
woods, efpecially in the prefent times, 
when the {carcity of wood becomes an ob- 
ject of general complaint in almoft every 
country. The Annals of Gardening, to- 
gether with a General Intelligencer jor 
Gardencrs and Florijis,” by NrUENHAIN, 
junior, No. V. and VT. concluding the 
firft volume with an Index. Among the 
numerous journals of this nature publithed 
in Germany, this may be fately pro- 
nounced the moft intereiting and ufefwl to 
the praClical gardener; and. we fincerely 
with the editor may continue his laudable 
excruions in this agreeable branch of ceco- 
nomy. Another work on the fame fub- 
ject, equally praifeworthy, but of a more 
generally uleful tendency, is the follow- 
ing: “Ox the Plantation of an artificial - 
Orchard, and the Vegetation of Plants,” by 
Dr. A. F. A.-DIEL, »vith three plates, 
and a catalogue of fruits, pp. 492, 8vo.
