6. Hooker, Species Filicum, being Descriptions of all known Ferns: 
allustrated with Plates. London: Pamplin. Part VI, or vol. ii, part IL. 
pp. 61-124, tab. 91-110, 8vo.—This part contains more North Ameri- 
can species than any of its predecessors. It is principally occupied 
with the difficult genus Cheilanthes, of which 70 species are described ; 
those of our own country being: C. microphylla, Swartz (New Mexico, 
Wright, No. 823); C. Wrightii, Hook. (New Mexico, Wright, No. 823); 
- Alabamensis, Kunze (Pleris Alabamensis, Buckley, in this Journal, 
1843); C. tomentosa, Link (N. Carol. to New Mexico, Wright, No. 
$16); C. Bradburii, Hook. (Upper Missouri, Bradbury, Texas, Drum- 
mond, Lindheimer, fase. 4, No. 743); C. vestita, Swartz ? (Missouri, 
&c., New Mexico, Wright, No. 818) ; C. Lindheimeri, Hook. (Texas, 
Lindheimer, fasc. 4, No. 744, Wright, No. 817); C. Fendleri, Hook. 
(New Mexico, Fendler, No. 1015); C. aspera, Hook. (New Mexico, 
Wright; probably from Texas) ;—a large addition to our known spe- 
cies. The other genera are Cassebeeria, Onychium, and Hypolepis. 
given, in a condensed form, but with much neatness, We rejoice to 
hear that the seventh part of this invaluable work may soon be expected. 
it must prove still more interesting to North American botanists.

7. N. B. Ward, F.R.S., &c., On the Growth of Plants in closely 
Glazed Cases. Second edition. London: Van Voorst, 1852. pp. 148, 
12mo.—The first edition of this little treatise, published in 1842, is 
doubtless well known to many of our readers; and some may remem- 
r Mr. Ward’s original account of his interesting discovery of a method 
of growing every sort of plant in the dun atmosphere of the smokiest 
part of London, published in the Companion to the Botanical Magazine, 
in 1836. This new edition if reduced in size is increased in interest, 
and. is embellished with tasteful illustrations on wood, several of them 
exhibiting approved forms of those glazed cases with which the name 
our author is inseparably connected. The first chapter, on the natu- 
ferns as the Trichomanes radicans, which is utterl i i 
> y uncultivable in any 
other way. A fourth chapter treats of the conveyance of living plants
