tematic botanists. A particular account of a volume which is or soon 
will be in the hands of every working botanist, cannot be necessary, 
and we have not time at present for special enumeration. The 9th 
volume commences with the Loganiacee, by Alph. De Candolle. The 
genus Ceelostytis, Torr. and Gr.,is correctly reduced to Spigelia. 
Under this order we have a tribe created for the long-vexed Gelsemium, 
which we suspect is not yet finally at rest. Next follows the Gentiana- 
ce@, elaborated by Grisebach, whose recent monograph of that family, 
which forms the basis of the present arrangement, was duly noticed in 
this Journal. The order Bignoniacee is edited from the manuscripts 
of the elder De Candolle; as also are the orders Sesamee and Crytan- 
drace@, which last has been reduced by Mr. Brown to Gesneriacez. 
The Hydrophyllacee are elaborated by Alph. De Candolle, in which, by 
attributing generic importance to the presence or absence of the ap- 
pendages or nectariferous scales within the tube of the corolla, the 
number of the genera is perhaps too greatly increased. The Polemo- 
niace@ are admirably worked out by Bentham, who has reduced to sec- 
tions of Gilia his Hugelia, Fenzlia, Linanthus, Dactylophyllum, Leptosi- 
phon, Leptodactylon, and the [pomopsis, Michx. The elaboration of 
the Convolulacee by Prof. Choisy, does not appear to give entire satis- 
faction to botanists. The term “ infelicissime intricatus” is perhaps 
still applicable to the family ; and the genera are probably unduly in- 
creased in number. Of the Borraginea, printed from the elder De 
Candolle’s manuscripts, with valuable notes and additions by the editor, 
we have the first three tribes, viz. Cordiew, Ehretiee, and Heliotropee. 
But for the true Borragee we must wait until the appearance of the 
tenth volume, which is already in press. A. Gr.

des principes de la Classification Naturelle et de Vart de décrire et 
@etudier les Vegetaux; par Auc. Pyr. De Canpouie. ‘Troisieme edi- 
tion; publiée par M. Aupu. De Canpo1te, d’apres les notes et les manu- 
scrits de Auteur. Paris, 1844. pp. 468, 8vo.—We are glad to an- 
nounce the publication of a new edition of the Theorie Elementaire, 
one of the earliest and most important of the lamented De Candolle’s 
writings, and which has left the most durable impress upon botanical 
science. The second edition, published in the year 1819, has long been 
out of print; and the illustrious author had intended, we are told, to 
prepare a final edition as a sequel to his herculean undertakings in sys- 
tematic botany, to perfect the expression of the theory after it should 
have been applied to the elucidation of all the known families of plants, 
and have been itself tested and corrected by the application. Finding, 
however, that life was too short for the accomplishment of these vast
