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 Linnsean 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 Schrceter* andBornf, 

 illustrated by figures ; those of the latter are very 

 well drawn, and delicately coloured, but those of 

 Schrceter, in this and his subsequent publications, 

 are indifferent, even for this period. Merram:]:
