Experiment XVI. 
A dog was killed, eight hours after receiving 
a large wound in his neck. The wound had 
during this time inflamed confiderablv. Upon open- 
ing him next morning, when he had been dead thir- 
teen hours, a large whitifh polypus was found in the 
right ventricle of his heart; under this was a little 
blood (fill fluid, which being taken up with a tea- 
fpoon, was found to coagulate foon after being ex- 
pofed to the air. 
It may be proper to obferve here, that in the hearts 
of animals which had died without any inflammation, 
I have found the blood entirely coagulated long be- 
fore this time. And that from opening them at dif- 
ferent times, I find it coagulates in their hearts after 
death, in the fame gradual manner that it does in 
their veins, when its motion is flopt by ligatures j

In the next place, that the blood is really attenua- 
ted in inflammatory diforders, where the whitifh cruft 
or fize appears, is probable from the following cir- 
cumftances; firft, it even leems thinner to the eye } 
2dly, the red particles, or globules fubfide fooner 
in fuch blood, than in that of an animal in health : 
this feems proved by obferving that in the above-men- 
tioned experiments, where the blood was at reft in 
the veins, it was npt covered with a cruft, except in 
one or two inftances, though in all thofe cafes it 
remained longer fluid than the blood commonly 
does in a bafon where the cruft appears. And again, 
the blood in the heart of an animal that dies a vio-
