liquid with precipitate evaporated to dryness. The residue — 
was then boiled with 96 per cent. alcohol. On evaporating off © 
the alcohol a yellow non-crystalline varnish-like residue was _ 
left. This residue was bitter, partly soluble in water, and ~

obtained did not exceed a trace. 
: The method of extraction above described was subsequently. 
A ' modified in the following manner :— 
An alcoholic extract obtained from 263 grams of the wood 
was digested at a gentle heat for some hours with water 
' acidulated with 2 per cent. of hydrochloric acid. The deep 
yellow solution was filtered, rendered alkaline with ammonia, 
In water hie extract was only slighily soluble, but in water 
acidulated with a few drops of nitric acid, it was wholly — 2 
soluble, with the exception of a few flakes, On spontaneous 
vaporation of the nitric acid solution a yellowish non-crystalline 
idue was obtained, not easily soluble in cold 96 per cent.
