lil. ‘The substances which had been dissolved by the alco- 
hol consisted of two portions, viz. the wax, which was of an 
apple-green color, and a reddish brown substance ; this, sub- 
stance was supposed to be resinous, and the contents of the 
retort were therefore digested in acetic acid; the acid soon 
became of a reddish brown color, and dissolved nearly the 
whole of the matter in the retort, leaving the wax. The aci 
solution, together with a small portion of insoluble reddish mat- 
ler, were carefully separated from the wax. ‘The wax being 
dried and melted, weighed 16 grains. 
IV. The acetic acid solution was evaporated to dryness, 
anda dark brown matter was obtained; it was almost totally 
soluble in warm alcohol, from which it was precipitated by 
water; it was supposed therefore to consist chiefly of resin, 
with a small portion of extractive matter, and may be called 
resino-extractive ; it weighed 2.5 grains. 
-V. The matter insoluble in alcohol consisted of two parts, 
viz. the kernels anda fine-grained black powder, having very 
much the appearance of fine gunpowder: the powder was 
carefully separated from the kernels by a wire sieve, and 
Weighed 7.5 grains. The kernels were fonnd to weigh 23.75 
Stains.
