soo ^ Treatise on 
Helmjlat 1693. relates, that he had fome of it given 
him by a Perfon of Diftindtion, at that Time juft 
returned from England , who told him that it was 
then the Cuftom in England to mix it with Tobac- 
co, in order to render it mote agreeable for fmok- 
ing. He likewife tells us, that a while after he 
procured fome of the fame Bark from John de 
Breyn , a wealthy Merchant of Amjierdam and an 
ingenious Yirtuofo : But all he could learn from 
him in Regard of its Qualities, was, that being 
mixed and fmoked with Tobacco, it corredted in

and that if it were put in too large a Proportion 
with the Tobacco, it occafioned Drunkennefs. Some 
Years afterwards, the Merchants fold it in the pub-

The Tree which bears this Bark is hitherto a

44 to be wholly rejedted, fince it is replete with 
44 refmous and balfamick Particles which are not 
44 unfriendly to our Bodies.”

Gout and other Affedtions, and found by Experi- 
ence that it poffeffed a carminative and diuretick 
Virtue. 
He likewife prepared another Tindture with the 
volatile Salt of Hartfhorn and Spirit of Wine, 
which was nothing inferior to the former, though 
of a lefs faturated Colour. He prefcribed both 
thefe Tindtures to gut, xx, orxxx. to be taken in a 
Morning
