at that time profeflbr of chemiftry and natural hiftory 
at Peterfburg, and now at Tubingen, went much far- 
ther, and has given us a very great number of new, 
curious, and ufeful obiervations, concerning the na- 
tural hiftory of that vaft and unknown region. The 
abundance of matter, and the limits of an extract, 
obliged Dr. Fothergill to confine himfelf, principally 
to the geographical and meteorological part of the 
work; but as the contents of the fecond volume are 
chiefly botanical, I find myfelf obliged to take a re- 
view of the fir ft volume, to introduce with propriety 
an account of the contents of the fecond. 
The Flora Sibirica contains the plants, which 
grow fpontaneoufly in a region of vafh extent, bounded 
by the Vralenfian mountains on the weft, the ocean 
of Kamtfchatka on the eaft, the Mare glacialc on 
the north, the countries of Kalmucks and Mongales, 
and the confines of China on the fouth. Our author 
has, among the productions of thefe countries, inter- 
fperfed a few plants, collected by that excellent bota- 
nift Gerber, near the rivers Don and Wolga, and in 
the Ukraine ; partly becaufc many of the fame kind 
grow in Sibiria, and partly from a defire that thefe 
curious plants fhould no longer be concealed from 
the public. Pie lias given no plant a place, which he 
himfelf hath not examined, at leaft in a dried ftate, 
and of which he is not fatisfied of its generical cha- 
racter. 
The plants of Kamtfchatka were collected by two 
of their company, detached for that purpofe. Of thefe 
George William Steller is mentioned by our author, 
witli very great refpeCt, for his uncommon zeal and 
proficiency
