RISE AND PROGRESS OF ZOOLOGY. 59 
extensively both in Europe and Asia; and described 
with more than usual accuracy the animals he met 
with; he was also a very good comparative anato- 
mist, and having no other profession to distract his 
attention, and being blessed with a long life, he 
had time to acquire considerable knowledge in all 
departments of nature, not excepting botany and 
mineralogy. He was more especially engaged by 
Catherine II. to travel through the Asiatic pro- 
vinces of Russia, with a view to investigate their 
natural productions. His travels, published at the 
expense of his munificent patron, were translated 
into French, and subsequently into English. Pallas 
was undoubtedly the most accomplished zoologist 
of the Linnean school, and, if he was not the author 
of any striking or important discovery, he accom- 
plished more, in other ways, than any one of the era 
in which he lived. Two works upon systematic con- 
chology appeared in 1779, by Schreeter* and Born, 
illustrated by figures; those of the latter are very 
well drawn, and delicately coloured, but those of 
Schreeter, in this and his subsequent publications, 
are indifferent, even for this period. Merram ¢
