b o o k t t t i i e ftock of human knowledge with difcoveries, the greateil
.<( part entirely new, and which no perfon but Mr. Pallas is
“ able to communicate
In the fame year in which this author printed his Elen-
cbus Zoopbytorum, he alfo put forth a treatife, under the title
o f Mifcellanea Zoologica quibiis nova imprimis atqus obfcura
Animalium fpecies defcribuntur et obfervationibus iconibufque
illnjlrantur. Hagæ Comm. pp. 1 18 , with 14 copper plates.
This work is in a great meafure incorporated in to a fubfequent
publication, made the next year on his return to Berlin, entitled,
Spicilegia Zoologie a ; and which has been continued in
numbers, orfafciculi, at uncertain periods, until 1780, when
the 14th was delivered. It contains, befide the letter prefs,
7 2 plates, and has reflected the highèft credit upon the author,
as a moil carefulobferverandcritick in zoology: it comprehends
a rich magazine o f knowledge for future writers,
riot only from the great number of new animals difcovered in
confequence of his travels through the Ruffian empire, but
alfo from a vail fund o f new obfervations on thofe before
known, and particularly from the light he has thrown upon
the defcent o f feveral o f the domèfticated kinds, the origin o f
which had been hitherto involved in the utmoil obfeurity.
The writings of count Buffon,the illuilrious French zoologiil,
amply teilify the labours o f Pallas in the fupplementary volumes
: and our own excellent writer on the fame fubjeCl, Mr.
Pennant, makes frequent acknowledgements o f his obligations
to the fame fource, particularly for his new edition of the Sy~
nopfis o f Quadrupeds, having received from Mr. Pallas con-
fiderable additions and corrections communicated in a long
fériés o f letters.
