* 1.1TO try what effects Air would have upon Vipers, (Animals constituted differently from other Creatures) January 2, 6 ⅖ A Viper was shut up in a Receiver; as the Air was drawn out she began to swell, and soon after we ceas'd Pumping, she began to Gape. In 2 ½ hours she did not appear to be quite Dead: Soon after
she gap'd, the swelling subsided, but presently rose again.
ANother Viper being shut up in Vacuo, after she had mov'd a little up and down, be∣gan to froth at the Mouth; soon after we left pumping, her Body and Neck swell'd prodigi∣ously, and a Blister rose on her Back, 1 ½ hour she appear'd to be alive, but no longer. Her Neck and a great part of her Throat seem'd transpa∣rent; Her Mouth was open and distorted; The Epiglottis with the Rimula Laryngis was almost thrust to the end of the Neather Chap. The black Tongue arising from beneath the Epiglottis, raught beyond it, but seem'd dead. The Mouth was black within. Upon a Re-admission of Air, in 23 hours, the Mouth was shut, tho' it open'd again. Scorching or pinching the Tail caus'd Mo∣tion in the Body of it.
* 1.2A Snake, being inclos'd 22 hours with a Gage in a Receiver, seem'd dead; but when held something near the Fire, put out her forked Tongue. The next day she was dead, her Jaws gaping as if stretch'd with Violence.
