An. Illustration of the Genus Cinchona; comprising Descrip- 
tions of all the Officinal Peruvian Barks, including several 
New Species, @c. Fo. By AYLMER BourKE Lampert, Esq. 
F.R.S. A.S. and G.S. Vice President of the Linnean Society, 
&c. &c. 4to. pp. 180. London, 1821. 
If, as will scarcely be doubted, the Bark is one of the most im- 
portant plants in the whole vegetable kingdom, then every infor- 
mation respecting the varieties of its species, the places where it 
is to be met with, and the medicinal qualities it possesses, must 
be considered as a valuable addition to the knowledge hitherto 
attained on the subject. Since the first discovery of this va- 
luable plant to the present moment, no one has devoted so much 
attention to itas Mr. Lambert. In 1797 he published a De- 
scription of the Genus Cinchona; but since that time so many 
additions have been made by the illustrious travellers Humboldt 
and Bonpland, as well as by the authors of the Flora Peruviana, 
that he has been induced to give some additional illustrations on 
the subject. 
Mr. Lambert entirely confines himself to the botanical defini- 
tions of the species, and gives more correct diagnoses of the spe- 
cies than has hitherto been done. To these he has added an 
account of the Cinchona Forests of South America, from the 
German of Humboldt; a Memoir on the different species of 
Quinguina, by Mr, Laubert, translated from the French; and 
four dissertations on various plants of South America, These 
documents afford every information relative to the history and 
various qualities of Barks, and contain much that is valuable and 
interesting, not onlv to medical men, but to the general reader. 
It would be foreign to our purpose to quote Mr. Lambert’s syn- 
opsis and description of the various species of Cinchona, which 
are given with that care, minuteness, and scientific detail, which a 
skilful botanist alone could appreciate.
