    ©f animals, fmoke of metals, «Src.—How patrld, mephitlc, or poiroTi- ous airs are produced, affedl animals, and are cured.—How vege- tables produce good air, and cure bad.—-The antifeptic qualities of fixed air (or aerial acid) related (with the mode of its pi:pdu6lion) as a probable cure for putrid diforders.—Dephlogijticated, 'vital, or em- pyreal produced—how an ingredient of inflammation, and of ne- cellity in breathing.—Inflammable air produced—proved to be oar neareft approach to elementary phlogillon—the fame in all inflam mable bodies—the otlier ingredient (with vital air) of inflammability in all combuftible bodies—calxes revived by it, and air balloons filled with it. Nitrous, or trial air produced—alio acid air, alkaline air, phlogifticated air, fluor acid air^ &c. 5. Water produced by the inflammation of two airs, and irsa burning as a itick. LECTURE vf. Hjdroftaucs, !• T TOW far water is compreflible—proved by the Florentin: and Mr. Canton's experiments—the pulfe-glafs, &c. 2. That it prefles in all direftions alike, according to its perpen- dicular height—proved by pillars of particles—'fpecific gravities—-! models of fmoking chimnies, and their cure—by hydrometers—by lead made to fwim, and cork to fink—by a new experiment to fii-j-.v how much its prcfTure is againft banks, fiocd-gates, fides of perpen- dicular pipes, tops of drains^ &c.—by the hydroftatic paradox—• by fwimming—hy_Fa:tx'& figures—by the bed made in water by a fliip—and by fountains. 3. What folids heavier than water lofe by being immerfed in it—., proved by weighing lead, brafs, gold, &c. in air and water—by the alloy found in King Hiero'^ crown, and in Englifh and foreign coins, i 4.
