fent day, and his mode of reafoning on 
fubjeéts of the firft importance, are al- 
ready known in this country, by two 
different publications, which have lately 
appeared. on the elements of the critical 
philofophy*. — 
ARTS AND MANUFACTURES. 
Tt cannot be faid with juftice, that the 
Germans excel either the French or the 
Englith, in this profitable department ; 
but if they are deficient in the pradtical 
part of technology, their method of writ- 
mg on fubjeéts of the arts and manufac- 
‘tures certainly is more fyftematic than 
im other countries, where human inge- 
muity tends to perfeétionate the practice, 
rather than the theory, of the arts. The 
ateft and moft. important work in this 
branch of knowledge is ** The Commer- 
cial Encyclopedia, or a complete Manual 
“of Frade.and Commerce, reduced to a 
fyftematic Order,” by G. H. Buse. The 
firft part of this work, which only ap- 
_peared in May laf, contains a fyftemartic 
-arrangement of all articles of merchan- 
dife, accompanied with, their chemical 
-tefts or eriteria, which are pointed out 
and defcribed in the plaineft manner 
by one of the firft German chemifts, 
Frof. TrommsporF. We with fora 
fpeedy continuation of this valuable work, 
which, on, account of its general utility, 
fy tematic arrangement, and concifenefs, 
furpaffes every work of the kind hither- 
to publithed. Another work, not unlike 
the Englifh Repertory of the Arts and 
Manufactures, but on amore extcnfive 
plan, is “* J.G. Geiscer’s Defcription 
and Hiftory of the principal Inftruments 
-and Machines of the moft recent Inven- 
tion, and their mechanical. Application ex- 
plained upon feientific Principles; for 
the Ufe of Artifts and Amateurs.” In 
Part VIIE. we find, befides many other 
curious articles, a defcription of WHIE- 
SENMANN’S failing windmill, and a 
well written view of the labours of 
Meffirs. BLAKE, COOKE, FRANGOTS, 
TrHomson, Maura, and FIrzce- 
RALD, onthe fubject of fteam and fteam- 
engines. The editor concludes this 
yolume with an acc unt of a new Invent- 
ed ree!, by Mr. Prassen, and an in- 
terefting examination of aftronomical 
rings, by CounT DE Bruye. A work 
chiefly defigned for the ufe of fchools, 
_ and the amufement of diletant:, is * The 
Conjuror’s Mechanifm, or a Defeription 
of mechanical Amufements, with the

amufement, and to ftimulate beginners 
to the farther profecution of the ftudy 
of mechanics. “ The new Mifcellany 
on Subjects of the Arts, &c. heing a Con- 
tinuation of the new Mufeum for Artifts, 
by J. G. Meuse.” The eight num- 
bers, which have appeared of the new 
feries, are no lels interefting to the man 
of letters, than they are inftruétive to 
the practical artift. “ The Correfpon- 
.dence relative to the Arts, between C. 
L. v. HAGEDORN and his friends, pub- 
lifhed by T. Bapen, Prof, in Kiel, &c.”” 
contain valuable ftriétures on painting,and 
an impartial examination of many piéturés 
belonging to the gallery of the late Mr, 
H. His letters are replete with found re- 
_marks on every fpecies of painting; and 
his ftyle evinces the paffionate lover of 
the arts. The charaéters here exhibited, 
of feveral painters of eminence, deferve 
to be read and ftudied by every friend of 
the arts, particularly thofe of Bots, 
Beicu, ORIENT, QUERFURT, NICH, 
BERCHEM, Mreris, F. MILeT, OESER, 
and Carres. * The Direétory (Ad- 
drefs-Lexicon) of the Manufaétories of 
Germany, and fome neighbouring coun~- 
tries; or a Lift of the Manufa@urers in 
thofe Countries, their Prodyétions, and 
the Fairs which they frequent,” is 2 
work of general utility, and the fir/ at- 
tempt of the kindin Germany. As the 
goods and articles of trade are alphabe- 
tically arranged, and accompanied with 
concife explanations relative to the value 
and quality of merchandife, this * Direc- 
tory’ is pecuiarly calculated to inftrucé 
the young beginner, as well as the expe- 
rienced merchant. |
