figures, with analyses, of the rare or little known plants of Russia, 
accompanied by corresponding descriptions in Latin. A hundred . 
such plants will constitute a volume. The vast extent of Russian 
dominion in the northern hemisphere, and it is destined to include 
species of the North American, as well the European and 
Asiatic territories, render this work important to those engaged in 
the study of the botany of all our temperate and northern regions, 
both of the old and the new world. The students of the North 
American Flora, and especially those of our own newly acquired 
possessions in north-western India, as of the “countries adjacent 
to this part of India,” so admirably described in the “ Gazetteer,” 
recently published by Edward Thornton, Esq., will find this work, 
along with Ledebour’s Flora Rossica, most useful in their botani- 
cal researches : and all will tend to increase considerably our know- 
ledge of the geographical distribution of plants. We trust this 
work will meet with the encouragement it deserves. 
Emerson, G. B.; Report on the TREES and SHRUBS growing na- 
turally in the forests of Massacuuserts: published agreeably 
to an order of the legislature, on the Zoological and Botanical 
survey of the state. Boston. 1846. 
It is worthy of a great nation, like that of North America, to 
employ its scientific men, as it is now doing, in reporting on the 
natural productions and resources of its vast continent. The present 
volume concludes the work of the commission on the zoological 
and botanical survey of the State. It has been prepared with 
especial reference to the instructions of Gov. Everett, and direct- 
ing the commissioners, “to keep carefully in view the economical 
relations of every subject of their enquiry.” 
Much on the subject was done by Michaux in his North Ame- 
rican Sylva. But the progress of botany, and experience in the 
uses and qualities of the objects under consideration, have thrown 
a new light on the history of trees and shrubs: and Mr. Emerson 
seems to have availed himself of the information to be obtained 
from books, from personal friends, and from his own practical
