    fately afcertained. The heat of a lamp being now applied, an elaftic fluid foon began to come over, which was collcdied in a gradu- ated jar. After allowing the water to boil for about a quarter of an hour, no more gas was given out; and as the water itfelf was now beginning to boil over, the procefs was flop- ped, and the refult examined. For this pur- pofe, the quantity of air colleded in the jar, was carefully noted, and a folution of cauflic alkali being introduced into it, a quantity of gas equal to TVths of an inch, was immedi- ately abforbed, which, of courfe, was carbonic acid. Exper. II.—-With regard to the portion of air left in the jar unabforbed, it was found, (every allowance being made for prefliire and temperature), that its bulk was perfedly fimilar to that of the air contained in the apparatus: and this air being examined by the nitrous tefl, gave precifely the fame refult as atmolpheric air. Thefe two experiments were tried a fecond time with refults exadly fimilar.
