    ( ¢e ) VUI.—-LEaxperiments with oxygene and other airs, largely difributed through the cellular fubftance. Dr. Maxwell, affifted by Dr. Goodwyn and fome other friends of accuracy and genius, forced different airs under the {kin of animals, whence every perfon in any degree acquainted with anatomy, knows they would infinuate themfelves far and wide through the body, in confequence of the free communication between different portions of the cellular fubftance.—I. 4% pints of atmof- pherical avr were forced under the {kin of a bitch, weigh. ing 2olb.; the incifion was clofed by a future: the ani- mal appeared uneafy and indifpofed for 36 hours ; the puffing did not begin to fubfide before the gth day; on the goth, no air was left except a little about the lower part-of the belly.—II. 3 pints of air, in which a light had burned out, were forced under the kin of a dog weighing 13lb. For fome hours the animal appeared ftupid. The emphyfema or puffing feemed to decreafe during the gd day; on the 16th convulfions came on and frequently returned; on the 2oth the dog died, much debilitated. In three other experiments nearly the fame phenomena were. obferved.—III. 4 pints of oxygene air were .infufed in the fame manner into another dog ; flight uneafinefs was obferved for the firft hour, and afterwards the animal appeared exceedingly lively (maxima alacritas), Next day the emphyfema began to Jeffen ; by the 1oth all the air was abforbed. In another dog of iglb. 34 pints of this air difappeared in 8 days; inathird of 21lb. 9 pintsin 8 days; ina 4th of golb. 3 pints nearly in 7 days. The 2d and gd were affeéted as the firft dog; the 4th was in no way affeéted.—I1V. Car- bonic acid air was infufed into feveral dogs and rabbits, A large quantity (as much as 2 pints in a dog of 17Ib) difappeared during the operation; the reft was gradual] abforbed in 4—14 days. No inconvenience followed, except in one cafe where a pint of air infufed into a rabbit 3 months old, occafioned uneafinefs from diften. tion; bur even here the animal eat with a good appetite in half an hour. The inftantaneous difappearance of io much air in thefe experiments, was probably owing ' to
