To which he adds,that all violent States of Matter arCstot preternatural,it being a common Error, that nothing violent is durable, the Atmosphere we live in being always in a forced or compressed State. In In the Thirteenth Chapter,Mr. tioyU's Pneu-s'8. Xmatick Engin is described, and several Experiments try ed with it which fliew,that the Air a£ upon most Bodies by Virtue of it's Springiness, which inclines it always to expand j and by it's Weight; so that it gravitates oa Bodies below it, according to the weight or che incumbent Pillar of tbe Air. And by this Weight it raises Mercury, in Weather Glasses, and Water in Pumps. And by several txperiments made in an exhausted Receiver, it is evident, that though Gun Powder will not explode without the Pressure of Air upon it, nor will fire burn $ yet a Loadstone externally applyed to an exhausted Receiver, will have considerable Effects on Bodies contained in it, but Sounds are not propagated in Facuo. And he further shews, that two flat polished Marbles will adhere to one another by the help of the Compresstirc of the Atmosphere. And that the Weight of theAcmosphere was able to raise a hundred Pound Weight tyed to the sucker or a Pump,depressed when theReceiver was exhausted. To which Experiments he adds, others which (hew, that Filtration is caused chiefly by the Pressure of the Atmosphere and that the Proportion betwixt the Weight of Air and Water is as 1 to 338, and that the Proportion of Quick-silver is as 14000 to 1. He likewise made several Experiments and Observations, to find whatEffects ihe exhausted Receiver had on Animals included in it, aud how long they conld live without Air.
