EXPERIMENT III.

July 6. 76.* 1.1GOosberries included in a Receiver with as much Air as rais'd Mercury ½ of an Inch; in half an hour it was rais'd half an Inch more; in 7 hours it was rais'd to 5 Inches.
July 7 It rose 5
July 8 It rose 3 ½
July 9 It rose 3 ¾
July 10 It rose 4 ¾ Digits high.
July 11 It rose 4 Digits high.
July 12 It rose 4 Digits high.
July 13. The Cover was broke; and another substi∣tuted in it's Place.
July 14, 15, 16, 17, 18. There was no Change: The Fruit being ta∣ken out, Part was shut up in Vacuo; the rest with common Air. In four hours the Ascent of the Mercury was 4 Digits.
July 19. The Mercury ascended ½ in 14 hours; but because I suspected that some Air got out, I set the Screw, and in 9 hours the Mercury rose 11 Inches. The Cover broke and the Air was lost.

Hence it appears, that unfermented Goosber∣ries contain much Air, which they more readily afforded, when the Pressure of the Air, is taken off; tho when fermented they yield a great deal more in Compress'd Air.

Notes

Goosberries in Com∣press'd Air.
