EXPERIMENT XVIII.

Jan. 28. 78.* 1.1 I Put a Shrew-Mouse into a Glass, to whose Neck I ty'd a Bladder, stopping the O∣rifice, which being shut up in a Receiver, when the Mouse began to be sick, by pressing new Air into the Receiver, the Bladder was straitned, and tho' new Air could not pene∣trate into the Mouse; yet the Air it was shut up in being compress'd, it was much better, and being taken out, in a short time recover'd.

Another Mouse being shut up after the same manner, till it could scarce breath; when the Air was compress'd, its Respiration seem'd abated; upon which, the Receiver being open'd, and the Mouse expos'd to the Air, it could not breath much more freely; yet when Air was blown up∣on it with a pair of Bellows, it seem'd re∣liev'd; but being again shut up with compress'd Air, it breath'd less frequently, and died.
March 25. A Mouse being shut up in an Instrument be∣fore describ'd, when I perceiv'd the Mouse sick, I intruded Water into the Receiver, so that the Air was reduc'd into half the Space it possess'd be∣fore; upon which, the Mouse breath'd more rarely; but the Air being successively compress'd and left to it's liberty again, the sick Mouse seem'd to breath more lively in the common Air, than in the compress'd. Whence I conjectur'd, that the Air is to Animals as Food, which ought to bear some proportion to the Strength of the Animal. In Confirmation of which Conjecture, I shut up a Mouse in my Pneumatick Engin, and rarifi'd the Air so much, that it possess'd three times the Space it did before; upon which, the Mouse seem'd better, but presently began to be sick, yet underwent no sensible Alteration up∣on an intromission of Air: The like success happen'd three times successively, tho' at the last the Mouse died.
