EXPERIMENT. XII.

Nov. 29. 78. OYsters were shut in one Receiver with∣out their Shells;* 1.1 In another they were shut up in their Shells with common Air, and in a Third with Salt-water. These three being closed up with Screws, 3 Oysters in their Shells, and 8 taken out were shut up in Vacuo; where it was observable, that when the Air was exhausted, those which were without their Shells emitted large Bubbles, one of the others opened the Shell.
Nov. 30. The Mercury in Vacuo ascended a little, but in those 3 which were stopped with Screws it descended rather.
Decemb. 4. The Weather growing warmer, the Mer∣cury in the first Receiver was 7 Digits. In the Second, 0. In the Third, 3. In the Fourth 3.
Dec. 5. In the First 20. In the Second, 1. In the Third 3. In the Fourth 5.
Dec. 7. In the First the Height of the Mer∣cury was 30. In the Second 1 Digit. In the Third 3. In the Fourth 8. Other Oysters left in the open Air began to Smell ill.
Dec. 9. In the First it was 30; In the Fourth 11. In the Rest no Change.
Dec. 13. In the Fourth it was 14 Inches High.

Dec. 20. In the First it was 46. In the Fourth 24. No alteration in the others.
Dec. 21. In the 1st. 52. In the 4th. 25. No alteration in the others.
Dec. 22. In the 1st. 60. In 4th. 27. No altera∣tion in the Rest.
Dec. 27. In the 4th. 29. No alteration in the Rest.
Jan. 7. 79. The Oysters in the Third Receiver had Co∣loured the Water black.
Jan. 25. Some Bubbles were formed in the Turpentine, about the Commissure of the Receiver and Co∣ver, of that which was exhausted; the Height of the Mercury was not altered, but the Oysters being taken out Stunk: Those in the other Re∣ceivers Stunk, and were turned to a viscous Gelly.

From this Experiment it seems to follow, that Fishes yeild not so much Air as Flesh; yet they will Corrupt tho' not affected by the out∣ward Air.
