Continued in axilla eight hours, the coagulae were more collected, firmer, and more than half diminished. The fluid of a light whey, or thin gruel colour and consistence, with a few loose white flocculi, and a creamy pellicle on the top. Oct. 2.—Continued in axilla eight hours more, the coagulae were almost completely dissolved; fluid, the colour of rich strained gruel; a few light flocculi on the surface, but no creamy pellicle ; a little coarse sediment, or loose white coagulae at the bottom. Experiment 57. Oct. 3.—Put fifteen drops of gastric juice into three drachms of sweet milk, at the temperature of 65° ; a slight appearance of very fine coagulae was first exhibited, but not so as to become distinctly separated till after the temperature was raised to 85° or 90°, when the whole mass gradually formed into a tremulous jelly-like curd, which, after cooling, and standing at rest a few hours, separated into two about equal parts; a soft caseous sub- stance, and a thin light-coloured whey. Experiment 58. Oct. 3—Put two drachms of the soft caseous substance, formed in the above experiment (55), into one oimce of gastric juice, and placed in axilla six hours ; at the end of this time, the curd or caseous substance was nearly
