phy, by the fame Author, inentioned in 
eur laf Retrofpeét. Mr. Abicht cerrain- 
ly has made many corrections, and, we 
may add, improvements; however, his 
language is ftill fo obfcure, and the fun- 
damental ideas and principles of this fy- 
fem are ftill involved in fo much derk- 
nefs, that we are not capable of forming a 
clear and favourabie judgment of his 
fyitem. 
“ Aufpriiche der - Philofophierenden 
Vernunft,’ &c. &c. Band. t.u. II. 1798; 
pp. 272. u. 274. 8vo. Remarks of Phi- 
lofophifing Reafon, and of a pure Heart, 
on Subdjeéts which are highly Important 
to Mankind, colleéted from the Writings 
of ancient and modern Thinkers, with 
ragard to the Principles of Critical Philo- 
fophy. Ufeful as this collection is, we 
eannot approve of the chaotic irregularity 
which prevails m it, and of the want of 
critical tafte which the compilers, who 
fign themfelves Neu—rR and Wy1t—u, 
betray on almoft every page. 
«¢ Philofophifche Gedanken und Ab- 
handlungen,”’ &c. &c. Band. J. II. IIT. 
iV. 1798. 8vo. Philcfophical Ideas and 
Traéts, relative to the Critical Philofo- 
phy, bya Lover of Wifdom. ‘This col- 
le€tion occupies a principal rank among 
the beft popular philofophical works which 
of late have been publithed in Germany. 
The traéts are chiefly occupied with mo- 
ral fubjeG@ts, and we can fafely affert that 
not one of the great number of German 
philefophers, who have attempted to elu- 
cidate/ and to popularife the Kantian fy- 
fem, has been as generally fuccefsful as 
the anonymous editor of thefe volumes, 
which treat with the greateft clearnefs 
and precifion on the moft interefting and 
important fubjeéts of human inquiry. 
*¢ Lebens Philofophie,” &c. &c. von G. 
S. BAIL; 1798.8vo. Philofophy of Life, 
or Maxims of Wifdom and Virtue, &c. 
&c.. We are fully perfuaded that a col- 
leétion of maxims of prudence and virtue, 
colleéied from the writings of practical 
philofophers and cb‘ervers of man, calcu- 
lated for the capacities and the wants of 
the middle claffes, as the prefent by the 
author is ftated to be, would be eminent- 
ly ufeful if it were made by a manof fci- 
sence and experience. Mr. Bail feems not 
‘to be deftitute of either, and his collec- - 
tion really pofieffes confiderable merit; 
it were, however, to be wifhed that he 
had divided it into chapters, and render- 
ed it more ufeful by fyttematic order.

ginners and Amateurs ; being the Aftro- 
nomical Catechifm of Mr. SoeBuRG, 
revifed and augmented, by Profeffor 
BuGGE, and tranflated from the Danith 
Criginal; altered, and rendered more 
ufeful, by additional Annotations, by C. 
G.Jauw; with feven Plates. The Ger- 
man editor judged the afironomical cate- 
chifm, publifhed fome years fince by a 
clergyman of Zeeland, to be an excellent 
manual of popular aftronomy. Profeffor 
Bugge, one of the moft eminent aftrono- 
mers of our times, Was prevailed upon to. 
revife it, and to furnith many valuable 
additions. The German editor has alter- 
ed as much as poffible the catechifm form 
of the original, and added elucidations or 
the technical words; and, by a complete 
index, rendered it.a very ufeful book for 
the aftronomical tyro. It is written in a 
very lively ftyle, and affords many occa- 
fions for religious refle€tions.

this periodical work, which was begun. 
in the year 1797, deferves the thanks of 
all real lovers of fcience, as it is one of 
the moft compendious repofitories of: fct- 
entific lore, and conducted by a man 
whofe learning and zeal for the diffufion 
of pradtical knowledge render him per- 
fe€tly adequate to the important tafk 
which he has begun. It is to be wifhed, 
for the improvement of {cience, tnat he 
will continue to receive the encourage- 
nfent he has experienced hitherto.
