VIII Intravascular injection .
.

Death 1 hour, 20 minutes.
Blood taken 4 hours after
death and 3 hours 40 minutes
after the body had been set
in an incubator at 37°C.
Cardiac blood in a soft
black clot.
At first deep lake,
brightening very
slowly and never
becoming bright
scarlet.
Very conspicuous ; free nuclei
and partly solved erythro-
cytes, isolated or in masses,
abundant ; serum staining
very conspicuously with
eosin.
Very considerable at
the time the blood
was taken.
IX Intravascular injection .

death and 4 hours, 20 minutes
after the body had been set
in an incubator at 37°C.
Cardiac blood fluid,
forming a loose
coagulum on removal.
Very deep lake,
brightening consider-
ably on exposure.

isolated or aggregated in
dense masses.
Considerable at the
time the blood was
taken.

Venom, 0.01 gramme.
Dying, 44 minutes.
Blood taken, 44 minutes after
injection.
Coagulation rapid ;
contraction of clot
very slight.
Very dark ; gradually
brightening to dull
scarlet.

isolated or in great masses ;
serum pale red, 24 hours.

Blood taken, 3 minutes after
injection.
. . . . . .
. . . . . .
An abundance of more or less
completely free nuclei, iso-
lated or in dense masses ;
remaining erythrocytes al-
most all deformed.

clot.

lake-red on exposure.
Majority of erythrocytes
completely dissolved, and
the rest partially dissolved,
Very considerable at
the time the blood
was taken.
