AEther, how to produce inflammable air with the vitriolic, p. 384. Air from it 
does not evaporate as the aether itfelf, p. 388. Its exploflve force encreafed by cam- 
phire, p. 389. Great exploflve force of very pure dephlogiflicated air, and zether, 
p. 407. Reafon why a drop of it communicates to dephlogiflicated air a much

Air. Difference between Dr. Prieflley and Mr. Sheele about the noxious effefts of the

the body of the animal, p. 342. Explanation of Abbe Fontana’s formula to exprefs 
the diminution of refpirable air, p. 343. Experiment to {hew inflammable air worfe 
than common, p. 344, &c. Inflammable, better after being breathed than before, 
p. 348. Air from the lungs alters the nature of inflammable air, p. 349. Animals 
aflefted by inflammable air, more or lefs, according to their flze, compared with the
