Benjamin Delessert, who had accompanied his brother in his travels 
through France, Rusdiseriond and Great Britain, gathering for himself 
the interesting plants he met with, now united these different collections, 
which thus served as the basis of what is now one of the largest botani- 
cal cabinets of the world. ‘The actual number of plants it now contains, 
is estimated by Laségue at 86,000 species, represented by 250,000 
specimens. But this-is a much larger proportion of the known species 
of — than we should suppose it possible for any single collection to 
posse Many particulars of high interest to botanical readers, are 
sewer in the history of the different herbaria which have —_ time 
to time been added to this museum; such as those of Commerson, the 
naturalist of Bougainville’s voyage round the world; of Billardia iére, the 
two Burmanns, the Japanese herbarium of Thunberg, that of Ventenat, 
of Palisot de Beauvois, and nearly all the leading botanists and scien- 
tific travellers of recent times.*. The notices of. other principal Euro- . 
pean herbaria, comprised in the second part of the volume, also abound 
in interest; though in respect to many of them the author’s information 
is insufficient. A, Gr. 
A. De Candolle’s Prodromus, Vol. 9.—A year ago we had the 
pleasure to notice the 8th volume of this indispensable work, the first 
of the series under the editorship of Prof. Alphonse De Candolle. The 
ninth volume, now before us, was issued on the first of January last; 
and the forthcoming portions are in course of preparation under such 
favorable circumstances that we may now confidently look for the ap- 
pearance of a volume a year, and for the full completion of this Species 
Plantarum, according to the natural system, at no very distant period. 
We have already mentioned the arrangements that are made to secure 
this desirable consummation, and by which the work becomes as it 
were a series of separate monographs, prepared by the most skillful 
hands, under the superintendence of a common editor. Every botan- 
ist is aware of the improvement of the successive, volumes as they a 
peared from the unrivalled hands of the elder De Candolle ; and.a far. 
ther improvement is manifest in the later portions, slaicentad or re- 
vised by his son, especially in the: introduction of characters drawn 
from zstivation, placentation, the structure of the ovule, and other points 
which have only quite recently been turned to special account by sys- 
* We should not omit to mention an interesting little peheaiee of plants, a sou- 
venir, peanennys by De Candolle in the follow wing clause of his will: ‘Je prie 
de choisir dans or herbier cents plantes sie} ‘ai 7 aeontas le premier, et 
de les sctlvdad de ma part 4 mon bon et ancien ami Be os amin Delessert, comme 
témoignage de mes nttnnlats pour lui et pour sa famille.”
