The author of this work is well known for his journey 

 into the Altai ran^e of mountains in search of Botanical 

 information ; and for his learned work on the systematical 

 Botany of those regions. He now proposes to gather under 

 one head an account of the whole flora of the huge empire of 

 Russia, including the Arctic circle, all the region between 

 the latter, and where oaks begin to grow, thence to the coun- 

 tries of the Vine, the southern provinces, including the 

 Crimea and the mountains of the Caucasus, the lands of 

 Ural, of Altai, of Lake Baikal, and of Daouria, the East of 

 Siberia, the land of the Tschuktskis, Arctic Siberia, Kamt- 

 schatka, the islands of the Eastern ocean, and the Russian 

 possessions in America ; in a word, the work will be the flora 

 of a seventh part of the world. In this immense labour the 

 author has no doubt access to all the treasures collected at St. 

 Petersburgh and in the Russian colleges; and they could 

 hardly be in better hands. 



The first part of the first volume is before me. It follows 

 the order of DeCandolle's Prodromus, as far as Cistaceae, with 

 which it terminates. It occupies 240 pages, and will no 

 doubt prove an important addition to the systematical Botany 

 of the vast countries to which it relates. It comprehends 

 many interesting novelties, among both genera and species, i 



and we have nothing to complain of excepting the thinness of 

 the paper which allows the type on one side the page to dis- 

 figure that on the other, and which, in the country where 

 paper is cheap, is not very creditable to the publishers. 

 Nothing so bad would be produced in dear England.
