To one, I added one drachm of albumen ; white of egg; to the second, half a drachm of the yolk, and to the third, another drachm of albumen. Put the two first in axilla, and the other on the mantle-piece. At 9 o’clock p.m. the albumen in the warm gastric juice, in the axilla, had become quite opaque, with loose light-coloured sediment at the bottom. The albumen in the cold gastric juice remained unaltered. That containing the yolk, exhibited the appearance of a mere mixture of fine yellow coagule, resembling sulphur and milk mixed together. On the 12th, at 8 o’clock p. m., both vials having been - continued on the bath, or in the axilla, through the day, the difference observed last evening, between the cold and warm vials of albumen, was very little increased. The yolk was considerably altered from a loose coagulee, generally diffused through the gastric juice, to a fine compact body of coagule, rising upon the top of a per- fectly clear transparent fluid, free from a particle of sedi- ment.
