EXPERIMENT XVI.
A dog was killed, cight hours after receiving
a large wuund in his neck, The wound had
during this time inflatiied confiderably. Upon open-
in£» hiin ncxt morning, when he had been dead thir-
teen hours, a large whitifh folypus was found in the
right ventridc of his heart; und.er this was a little
blood ftill fluid, which being taken up with a tea-
fpoon, was found to coagulate foon after being ex-
polcd to the air.
It may be proper to obferve hère, that in thc hearts
of animais which had died without any inflammation,
1 hâve found the blood entirely cbagulated long be-
fore this time. And that from opening them at dif-
ferent times, 1 find it coagulates in their hearts after
death, in the famé graduai manner that it does in
their veins, when its motion is ftopt by ligatures
as related pag. 380.
In the next place, that the blood is really attenua-
ted in inflammatory diforders, where the whitifH crufî
or fize appears, is probable from the following cir-
cumftances; firft, it even feems thinner to the eye;
zdly, 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 not covered with a cruft, except in
one or two inftances, though in ail thofe cafés it
remained longer fluid than the blood commonly
does in a bafon where the cruft appears. And again,
