Ail inflammable air, according to the antiphlogiftic hypothecs, comes from water 
only, ibid. A final! quantity of inflammable air is procured, by fending a fleam over 
melted fulphur, p. 15. Inflammable air produced by a diflolution of iron in diluted 
vitriolic acid, ibid. Vitriolic acid air contains the fame inflammable principle with 
inflammable air, p. 16. Nitrous air, when mixed with dephlogifticated air, has no 
tendency to produce phlogifticated air, p. 149. Nitrous air has no effedt on phlo- 
gifticated air, ibid. Nitrous air does not contain fo much phlogifton as an equal bulk 
of inflammable air, p. 150. Alkaline air converted into inflammable air, p. 29$. 
Nitrous air and dephlogifticatpd air by mixture produce nitrous acid; and nitrous 
air, by mere heat, is converted into a mixture of phlogifticated and dephlogifticated 
airs, .p« 309. Nitrous air changed into phlogifticated air, by abftradling from the 
nitrous air a quantity of dephlogifticated air, ibid. The reliduum of volatile alkaline 
air, after the calces of lead have been revived in it, is phlogifticated air, p. 311.

than it has to phlogifticated air, p. 312.
