the tube ; the other end was loofely Inferted two 
inches within the mouth of another large bottle, 
charged with four hundred grains of iron filings, and 
fixty ounces of diftilled ^ water. After remaining 
twelve hours 'in this fituation, the fugar working 
brifkly, an ounce phial was let down gently into the 
bottle, and filled. The water from the phial, with 
one drop of tindure of galls changed in a few mi- 
nutes to a light rofy purple. The liquor being 
fliaken, and another phial-full taken up foon after, 
one drop of the tindure gave a deeper colour than 
before. In an hour and half more, after being 
fliaken again, the phial-full received a flill deeper 
purple, from the like quantity of tindure. The bottle 
continuing as before near five hours longer; when 
the quantity of fixed air from the fermenting liquor 
was fuppofed fuflicient to have faturated the water ; 
the liquor appeared very turbid on being fhaken ; 
and, after flanding another hour, under the tube, to 
fettle, the whole was filtered. 
Thirty ounces of the clear liquor was poured into 
two Florence fiafks, and the remainder into phials, 
which were afterwards well corked. Two of thefe 
phials had their corks dipped into melted refin, fo as 
to cover the mouths of the bottles. Two others were 
enclofed with a pafte or lute. 
Notwithflanding the above precautions to prevent 
the efcape of air, the liquors in each foon grew tur- 
bid, and by the next morning depofited yellow fe- 
diments. 
* This tinilure was made by infufing half an ounce of pow- 
dered galls in eight ounces of proof fpirit, for four days, without 
beat.
