Half a grain of galls powdered turned a pint of 
Someriham water of a dark mazarine blue, inclining 
to purple. 
Experiment VIII. 
In two vials were poured forne Someriham water, 
each vial containing eight ounces. In one had been 
put two drams of filings of iron. After (landing 
twenty-four hours in a moderate warm place, three 
grains of powdered galls were added to each vial. 
The pure Somerfham water immediately turned 
purple, with the galls, which next day fell like a 
purple fed i men t to the bottom, and left the fuper- 
natant liquor clear. The water poured on the filings 
of iron threw up feveral air bubbles, turned black 
as ink, fome few hours after the addition of the 
three grains of galls ; and kept that color, and an 
inky tafte, feveral days after which the black fedi- 
ment fell likewife to the bottom, and left a clear fu- 
pernatant water, which hill preferved its inky 
tafte.
