spirit of wine. Oil of turpentine diffolves but a fmall 
portion of it, and acquires only a pale yellow colour. 
A folution of fixed alkaly in water, digefted with this 
fubftance, diffolves a large portion of its colouring part, 
and the folution is of a brownilh yellow colour. Volatile 
fpirit of fal ammoniac, feems to diffolve a larger portion 
of it than the fixed alkaly, and the folution is of a reddifli 
orange colour. A folution of foap in water, boiled with 
this fubftance, likewife diffolves its colouring part. All 
the foregoing folutions, except that in oil of turpentine, 
which was not tried, die fiik, cloth, and linen, of va» 
rious fhades of yellow and orange ; but thefe colours are 
difcharged, by boiling the dyed fubflances for fome time 
in foap and water. This colour can, therefore, be of 
ufe only in dying filk and wool, for which purpofe we 
are already furniflied with good dyes. Few colours go 
fo far in dying as this new fubftance, and none dye fo 
fpeedily, efpecially when foap and water are ufed as the 
folvent ; for a dip or two will dye cloth or filk of a lively 
yellow colour, when put into the mixture whilft hot^ 
Soap and water may be perhaps ufed with advantage, as 
the folvent for feveral other colours. 
From the foregoing experiments it appears, that this 
colouring fubftance, upon which they have been made, 
is of the relinous kind, and has a good deal of afhnity 
with annotta.
