Vi. Two fmall tin. veffels, containing each the white 
of an egg, v/ere put into the ftove heated to 224°^ One 
of them was placed on a wooden feat near the wall, and 
the other fufpended by a firing about the middle of the 
ftove. After ten minutes, they began to coagulate; but 
the coagulation was fenfibly quicker and firmer in that 
which was fufpended, than in that which was placed on 
the wooden feat. The progrefs of the coagulation was 
as follows : it was firfl formed on the fides, and gradually 
extended itfelf;‘the whole of the bottom was next co- 
agulated ; and lafl of all the middle part of the top. 
VII. Part of the fliell of an egg was peeled away, leav- 
ing only the film which furrounds the white ; and part 
of the white being drawn out, the film funk fo as to form 
a little cup. This cup was filled with fome of the albv.^ 
jnen ovi, which was confequently detached as much as 
pollible from every thing but the contadl of the air and 
of the film which formed the cup. The lower part of 
the egg flood upon fome light tow in a common galli- 
pot, and was placed on the wooden feat in the flove. The 
quickfilver in the thermometer flill continued at 224'^. 
After remaining in the flove for an hour, the lower part 
of the egg which was covered with the fhell, was firmly 
coagulated ; but that which was in the little cup was fluid 
and tranfparent. At the end of another hour it was flill 
fluid, except on the edges where it was thinnefl; and 
here it was flill tranfparent ; a fufhcient proof that it was 
dried, not coagulated.
