4thly. I then dipped the piece of flannel N° z. in 
the fame juice, and being defirous to clean my hands 
from the ftain, which N° i. had caufed, I ordered 
fome lime water to be brought me, fuch as we ufe 
to fettle our indico, and found the colour of the ftain 
change to a bright yellow. This unexpe&ed change 
urged me to throw a wine glafs-full of lime water 
into the pot, where the piece of flannel N° 2. was 
fimmering ; on which, all the juice, as well as the 
flannel, became of a bright yellow, by which I find 
alum fixed the crimfon, and lime the yellow.

two pint decanters, in one of which I put a fmall 
quantity of powdered arum, I laid them up : about 
lix weeks after, I then examined them, and found the 
juice in the decanter, which had no alum, was turned 
black, and the other retained its colour.
