Experiment XV. 
A woman, with a flight inflammation in her throaty 
had eight ounces of blood taken from her arm ; the 
blood was received into a bafon, and the bleeding 
finifhed in four minutes and three quarters, when 
a film was begun to be formed near the air-bubbles ; 
in feven minutes a tranfparent fize appeared over a 
confiderable part of the furface which was quite 
fluid, whilft the reft of the blood was coagulating, 
there being now a very diftindt red cruft over the 
reft of the furface. 
Now, from comparing thefe experiments with what 
has been obferved of the coagulation of the blood, 
where there is no inflammatory cruft or fize, is it not 
evident that the blood remains longer fluid after be- 
ing expofed to the air, and has lefs difpofition to 
coagulate, in thofe cafes where there is a fize, than 
where there is none ? for in thofe cafes where there 
was none it was found to coagulate completely in 
feven minutes; but in one of the others, where the 
fize was very thick, it was found not to coagulate 
completely in lefs than an hour and an half? 
The effeft that inflammation has in leflening the 
lymph’s difpofition to coagulate, is likewife plain 
from the following experiment, where the blood in 
the heart of a dead animal feems to have coagulated 
very flowly.
