remarks bearing on the peculiarities of the scenery, vegetation, 
geographical distribution, &c., intermixed with numerous scraps of 
poetry, a brief memoir of Mr. Don, and a longer one of Mr. 
Drummond. The author follows the Natural arrangement, and 
includes the Acotyledonous plants, though these, it may be 
presumed, are far from offering a perfect list, especially in the 
Alga and Fungi.

Asa Gray; Botany of the Northern United States. 1 vol. large 
12mo. Boston and Cambridge, U. 8. A. 1848. 
The name of Dr. Asa Gray is a sufficient guarantee for the 
good execution of this work, which includes an area of the United 
States, extending “from New England to Wisconsin and south to 
Ohio and Pennsylvania, inclusive.” This territory has been, doubt- 
less, better explored than any other portion of the United States, 
and probably as much so as any portion of Europe; and the book 
has, too, the rare merit among American Floras of including the 
Cryptogamiæ (Algæ and Fungi excepted) as well as the flowering- 
plants: the Lichens, indeed, being printed apart, as will be pre- 
sently noticed. The whole is arranged in natural families, and is 
accompanied by an introduction, containing “ Brief outlines of 
Botany,” and a “ Glossary of Botanical Terms.” The work is in 
English. The generic and specific characters are as brief as pos- 
sible to be useful; and there are no synonyms. It is, indeed, an 
admirable text-book for the student, whether in the field or in the 
Herbarium; and those who desire farther information on the 
plants of the Northern States, will doubtless have recourse to 
the Flora of N. America, by Messrs. Torrey and Gray, which, 
after some delay, is, we are happy to find, now progressing. 
Of the Botany of the Northern United States, the Musei and 
Hepatice are described by Mr. Sullivant, whose labours in those 
departments of Botany we have more than once had occasion to 
notice with high commendation.
