dws ; which is the fame with the former, only 
growing in a different Climate. The Refin is got 
from Trees about five or fix Years old by cutting 
the Bark quite through to the Wood, beginning at 
the 1'op near the Branches and carrying the Incifi-

flows out of the Tree, it is thin, fomewhat gluti-

and acquires a yellow or reddifli Colour *, or if it 
be fuffered to lie long upon the Bark it appears of

the Manner in which it is got, tells us that the

Benzoine affords by a chymical Treatment a 
large Quantity of Oil, whereof one Portion is thin, 
tranfparent, of a golden Colour, and fragrant, and 
the other is thick, having a Confidence like Butter ; 
together with a confiderable Proportion of acid

out by Decodlion in common Water. This Salt
