EXPERIMENT XVIII.

• Decemb. 23. A Glass Vessel being full of Milk,* 1.1 and stop∣ped with a Screw, was conveighed into one Receiver, and Milk with a Lark in it into another.
• Decemb. 24. In the Evening the Caseous and Butyrous Parts were separated both in the Milk in the Receivers, and in some of the same exposed to the Air.
• Decemb. 27. No Air generated where the Lark was; The other Gage was spoiled.
• Decemb. 31. The Mercury was raised in that which held the Lark. 3 days since, Milk that had all the while been exposed to the Air, Stunk.
• Jan. 1. 79. The Mercury was 10 Inches high, where the Lark was contained.
• Jan. 2. It was 14 ½. The Milk below the Buty∣rous Part seemed red.
• Jan. 4. It rose to 19 Digits. White Serum grew together in the Bottom of the Milk.
• Jan. 9. The Mercury was 29 Digits high.
• Jan. 25. The Receivers being opened, the Lark Smelled strong, but when Boll'd Tasted Plea∣sant; tho' it had been kept 32 Days. In the other Receiver the Butyrous part was sowre, but the Caseous Part Tasted subacid.

From hence it appears that Milk may Preserve Flesh.
