APHIL, 1 850. 
ART. XXVIIL— CALISAYA BARK. 
Translated and arranged by J. Carson, M. D. 
(With a Wood- Cut.) 
In the last number of the Journal, a general account was 
published of the labors of Dr. Weddell, in South America. 
He has been, as there stated, eminently successful in clear- 
ing up many doubtful points connected with the subject of 
Quinology. From the extent and importance of his me- 
moir, he has taken rank in scientific discovery with Ruiz 
and Pavon, Mutis, De La Condamine, &c. From the same 
work, on the present occasion, we shall extract the account 
of the source of Calisaya bark, the discovery of which alone, 
would have immortalized his name.
