That Air, in a fix’d State, is the Bond of Union, 
which makes Salts durable, and which keeps together 
the Solid Parts of Vegetables, of Animals, and even 
Globules of the Blood. 
That the Air in a moift State is fooner abforb’d by 
Sulphureous Steams, than in a dry State; for'a Candle 
which in a dry Receiver burn’d 70", burn’d but 64^^ 
in the fame Receiver when it was fill’d with the 
Fumes of hot Water ; but yet abforb’d one fifth part 
more of Air. But the abforbing Subftances Jofe their 
Force of acting, when united in a large Body, Brim- 
ftone in a Roll abforbing no Air, tho’ it does it fo 
plentifully when reduc’d into Minute Particles. 
»That fome of the Food of Animals generates, and 
fome abforbs Air, and the Digeftion in a healthy 
State is befi: perform’d when there is but a little Air 
more generated than is abforb’d. 
From the Confideration of the feveral Experiments 
made by our Author, in his Analyfis of Air, he makes 
it appear that our Atmofphcre is a Chaos of different 
Particles, fome of which are elaftick, and fome un- 
elaftick ; and that the elaftick Parts are endued with 
very different Degrees ef Elafticity, according as they 
are bigger or lefs, more or lefs folid, more or lefs 
watry ; and therefore that fome are eafily and fome 
more difficultly reducible to a fix’d State. 
That it is chiefly by the Change of Air from a 
fix’d to an elaftick, and from an elaftick to a fix’d 
State, that this beautiful Frame of Things is main- 
tain’d in a continual round of the Produdion and 
Dilfolution of animal and vegetable Bodies ; and 
therefore, that there is as much reafon to adopt 
Air among the Chymical Principles, as acid Sul- 
phur ; tho’ it has hitherto been rejected by the 
Chymifts. 
This will he continud in the next» 
FINIS.
