The elements of medical chemistry : embracing only those branches of chemical science which are calculated to illustrate or explain the different objects of medicine, and to furnish a chemical grammar to the author's Pharmacologia . marble and dilute sulphuricacid, be twice bent at right angles;and let the open end of the lowerleg reach the bottom of a glass jar,perfectly dry within, and standingwith Us mouth uppermost, as repre-sented in the annexed cut. Thecarbonic acid will expel the common air from the jar,and take its place, because it is heavier, just as waterwill, when poured into a vessel containing nothing butair. When the jar is thus filled with the gas,, (whichmay be known by a lighted taper being instantly ex-tinguished in it, when plunged a little below the brim)take another jar of rather a smaller size, and place atthe bottom of it a lighted taper, and pour the invisiblecontents of the former into the latter, as if you werepouring water, the candle will be instantly extinguished,although the eye i3 incapable of perceiving any thingpoured upon it capable of producing such an effect. In consequence of this superior gravity of carbonic acidgas, it is often found at the bottom of grottos, of deep wells,. 240 PARISS MEDICAL CHEMISTRT. and of mines, the upper part of which is entirely free fromit. In the grotto del cane, near Naples, so called from its airproving so destructive to dogs, has long been famous for thequantity of carbonic acid produced in it, which runs out atthe opening like a stream of water, and kills any small quad-ruped that enters it, whilst man, from his greater height maypass through it with impunity. 2. It extinguishes flame. This has been already shown byexperiment 64. 3. if is fatal to animals. If we introduce a mouse, orother small animal, into a vessel of the gas, and cover it, soas to exclude the access of common air, the animal will die inthe course of a minute or two. Its fatal effects upon man hasbeen illustrated by numerous exa
