Whence it appears that, without this atmo- fpheric preflure, we fliould not have any perma- nent liquid, and fhould only be able to fee bo- dies in that (late of exiftence in the very inftant of melting, as the fmallefl; additional' caloric would inftantly feparate their particles, ahd difli- pate them through the furroiinding medium. Befides, without this atmofpheric preflfure, we fliould not even have any aeriform fluids, ftriftly fpeaking, becaufe the moment the force of at- traftiori is overcome by the repulfive power of the caloric, the particles would feparate them- felves indefinitely, having nothing to give limits to their expanfion, unlefs their own gravity ' might collefl them together, fo as to form an atmofphere. Simple refleftion upon the moft common ex- periments is fufficient to evince the truth of thefe pofitions. They are more particularly proved by the following experiment, which I publiflied in the Memoirs pf the French Aca- demy for 1777, P* 426.
