EXPERIMENT IV.

Feb. 22. 77. TEN Ounces of Paste being included in a Receiver which was large enough to hold 22 Ounces of Water,* 1.1 I impress'd Air enough into it to sustain 73 Inches of Mercury above the length of a Cylinder which the Weight of the Atmosphere is able to bear up. In two hours there was no sensible Alteration.
Feb. 23. In 18 hours the Mercury was rais'd 7 Inches. And in 6 hours more it ascended 8 Inches higher, being buoyed up to 83 Inches.
Feb. 24 It was 90 Inches high.
Feb. 25 It was 97 Inches high.
Feb. 26 It was 101 Inches high.
Feb. 27 It was 105 Inches high.
Feb. 28 It was 107 ½ Inches high.
March. 1 It was 112 Inches high.
Water seemed to be expres∣sed out of the Paste.
March. 2 It was rais'd to 120 Inches.
March. 3 It was rais'd to 121 Inches.
March. 4 & 5 It remained at 121 Inches.
March 8. Upon a Thaw the Mercury ascended 4 Inches and rested at 125 Digits.
March 10. It rose 6 Digits higher, being suspended at 131 Digits.

March 21. The Season being so long Cold, no Air was ge∣nerated, except that in the three last Days the Mercury was rais'd 7 Inches, and rested at 138 Digits.
...April 4.
One of the Iron Wires made use of to straiten the Receiver, was broke, and the sides of the Receiver started out of their Places 4 or 5 Foot.

From whence it appears that Cold and Com∣pression hinder the Generation of Air.
