moniac, Sal Tartar , and fpirits of Wine 
mixed together, generated 26 cubiek inches 
of air, two of which was in # four days re- 
forbed, and after that generated again. 
Experiment LXXXIL 
Half a cubick inch of Sal Ammoniac , and 
double that quantity of Oil of Vitrioly ge- 
nerated the firft day five or fix cubick inches : 
But the following days it abforbed fifteen 
cubick inches, and continued many days in 
that ftate. 
Equal quantities of fpirits of Turpentine y 
and oil of Vitriol , had near the fame effcft, 
except that it was fooner in an abforbing 
ftate than the other. 
Mr. Geoffroy fhews, that the mixture of 
any vitriolic falts, with inflammable fub- 
ftances, will yield common Brimftone$ and 
by the different compofitions he has made 
of fulphur; and particularly from oil of 
Vitrioly and oil of Turpentine $ and by the 
Analyfis thereof, when thus prepared, he 
difcovered it to be nothing but vitriolic 
fait, united with the combuftible fubftance.
