daily increase so much, that we think it wiser to limit the 
number of Genera than unnecessaril to multiply them. 
Botanists have been too exclusively addicted to hunting out 
the differences among plants, so as to form new groups and 
genera. An opposite course might be preferable, that of 
discovering the analogies, similitudes, and connexion between 
them; and this research would seem more conformable to 
the philosophical spirit of the science, and would operate 
favourably on the future prospects of Botany. 
“The Plates represent chiefly the new species, or occa- 
sionally give details of those plants which offer something 
peculiar in their organization. The analyses are executed by 
ourselves, and with the greatest possible care."

Of this extremely valuable and beautiful work, seventeen 
livraisons are now before us, each consisting of four or five 
sheets of letter-press, and accompanied by ten partially but 
well-coloured plates, from the pencil of M. Heyland. Ona 
future occasion, we shall offer our readers some extracts from 
the highly interesting “ Narration ” contained in the first 
chapter. e shall content ourselves at present with an-

must be very near its completion; for it is announced to 
consist of sixteen or seventeen livraisons, and the letter- 
press (for the plates are published without order), following 
the arrangement of De Candolle, extends as far as the Che- 
nopodee. The price is extremely reasonable, considering 
the beauty, and execution, and accuracy of the plates; 18 
francs a livraison ; and we trust it will meet with the encou- 
ragement to which its great merits entitle it. 
M. Boissier, having brought his “ Flora of the South of 
Spain? to its present very forward state, has already, in the 
early spring, set out on his botanical travels into Greece and 
Turkey, and will not return to Geneva till the autumn. We
