The same moment aad the long aris of

while in Aiastole IL untwists again.
The circulation Of the blood is best
shown by the puneture Of Harvey. This
+ Is to push a troc4r inte the ventricles,

er giving the class a good chance TO
study the hearts movement beat the
professor plunged hollow needle or
trocar, about one-eighth of an inch in
I diameter, into the left ventricle, and Jet
after JET came jumping out, driven by
/ the punp-like action of the organ, thus
T showing that blood was being constant
1 ~ forced onward or kept in circulation
/ by the contraction of the organ.
To complete the vivisection and to be
sure that the animal should not suffer
any pain the professor and his assistants
now opened the back of the animals
neck and sevssed the medulla oblongata
as high as the base of the skull. The
heart ceased beating-the victim was
dead. The animal had lived over an
hour with its heart exposed, and so per-
I feet was the vivisector's skill that the
hearts action did not even seem TO weak
en- in all that time, nor was there the
slightest sign of pain.
