Extract from a Letter from Mr. EGERTON. 
Buenos Ayres, né 30, 1881. 
From а роза I understand that the leaves of a shrub called 
* Jaborandi” are now exported in certain quantity to брата where 
a valuable alkaloid is is iiec eo from them that fetches a very high price 
in the drug market. 
ow in Paraguay this plant (leaves of which I send herewith) exists 
in such enormous quantities that, even should its richness in alkaloid be 
less than that from Pernambuco, n cost would be relatively very much 
ess. In it has no value in Par. у. 
The chief virtue as a drug of this “Jaborandi” known in Paraguay 
is that a decoction from its leaves is the strongest sudorific known.

SIR, Royal Gardens, Kew, September 8, 1881. 
I am desired by Sir Joseph Hooker to е the receipt 
of your letters of September 15% and 5th relating to . G: Be 
Egerton’s reports on certa vegetable produetions of Paragu i 
The rri of Jaborandi from this source, and -the information 
regarding it, is of great. interest. The drug, although a recent intro- 
duction to pharmacy, is one which has attracted much attention. 
looked into the matter, reports that, thou ugh the Paraguay and 
nambuco plants are extremely closely allied, it is possible that they im 
not absolutely identical. The medicinal proper ties are, probably, 
owever, similar. A portion of Mr. Egerton's sample has been 
preserved for the Museum of the Royal Gardens; the remainder has 
been divided between the Pharmaceutical Society, the Professor of 
Medicine at University College (Dr. Sydney Ringer), and Dr. Michael 
Foster, the Pralector of Physiology, Trinity College, Cambridge. І
