i4o Mr. Kirwan’s Experiments 
determined better than by any other method. Alfo the fmoak- 
ing liquor of Boyle, which is difficultly prepared in the ufual 
way, may eafily be formed by placing the volatile alkali in 
the middle glafs of Dr. Nooth’s apparatus for making arti- 
ficial mineral waters, and decompofing artificial pyrites, or liver 
of fulphur, in the lower glafs, by marine acid. 
0/7 of olives abforbs nearly its own bulk of this air, and ob- 
tains a greeniffi tinge from it. 
But new milk fcarcely abforbs one-tenth of its bulk of this 
air, which is very remarkable, and is not in the leaft coagu- 
lated. 
0/7 of turpentine alfo abforbs its own bulk of this air, and 
even more ; but then becomes turbid. Water feems alfo to 
precipitate this air from it, for when fhaken with it a white 
cloud appears. 
Spirit of wine , whofe fpecific gravity was 0,835, abibrbed 
nearly three times its bulk of this air, and became brown. By 
this means fulphur may be combined with fpirit of wine much 
more eafily than by Count Lauragais’ method, the only 
hitherto known. Water precipitates the fulphur in part. 
Sulphurated fpirit of wine does not tinge litmus red ; but it 
precipitates lime-water, as highly rectified fpirit of wine fingly 
does. It alfo precipitates and gives a brown colour to acetous 
baro-felenite, which fpirit of wine alone alfo does. It turns 
the folution of filver black and reddiffi brown. Concentrated 
vitriolic acid precipitates the fulphur from it, which neither the 
nitrous nor marine acids can effeft. 
When hepatic air is mixed with an equal bulk of vitriolic tether f 
the bulk of the air is at firft increafed ; but afterwards half of 
it is abforbed, and a flight precipitation appears. The fmell of 
the aether is mixed with that of the hepatic air; but on adding 
'i water
