mixture of vitriolic and nitrous acids by phlogiftication, p. 369. ExpcrimenTs on the 
precipitation of filver from nitrous acid by iron, p. 374. Experiments (hewing the 
alterations which iron or its furface undergoes by the action of a folution of filver in 
nitrous acid, or of a pure concentrated nitrous acid, p. 379. Experiments and 
obfervations on the matter of cancer, and on the aerial fluids extricated from animal 
fubflances by diflillation and putrefaction, and on animal hepatic air, p. 391. Expe- 
riments (hewing, in general, that the fetid odour of cancerous matter is increafed by 
vitriolic, but entirely deftroyed by concentrated nitrous and dephlogifticatcd marine 
acids; that the aerial fluid, which is cliftngaged by vitiiolic acid, is foluble in water; 
that the folution depofits a reddifti brown precipitate upon the addition of nitra ed 
filver, p. 392 — 397. Experiment (hewing that cancerous matter c ntains volatile 
alkali, p. 398. Experiments on the air extricated from cancerous matter, and fre m 
animal lubftances, by diflillation, p. 399. Experiment proving that animal hepatic 
air, when abforbed by water, is not capable of being again dilengaged by a heat 
which raifes water to a boiling temperature, p. 406. Experiment (hewing that, 
by the combuftion of pure and inflammable airs, fixed air is produced, p. 408. Expe- 
riments on the increafe of bulk which takes place when equal parts of pure and animal 
airs are burned together, p. 41 1. Ey experiment it appears probable, that animal 
hepatic air confi (Is of a combination of light and heavy inflammable airs; and that 
when it is fired with a quantity of pure air not fufiicient to laturate it, a portion of 
animal air is refolved into its elementary principles, ib. Experiments on the products 
which reful t from the combuftion ot lulphureous hepatic with pure air, p. 412* 
Experiment on the production of vitriolic acid by the combuftion of hepatic with

much the appearance of oil, is formed by the combination of fulphureous hepatic air 
with fixed air and volatile alkali, p. 417. Experiments on the air extricated from 
animal fubflances by putrefaction, p. 418. Experiments on the effeCts produced by
