TRANSMISSION.
An Interesting Experiment on Two
Dogs.

From the Buffalo Courier.
An interesting experiment, involving
the TRANSMISSION of blood, was made at
the Bu-alo Medical College, yesterday
afternoon at 2:30 o'clock, in the presence
of the students of the college. The oper-
ator was William H. Mason, NJ. D.,
Professor of Physiology, who prefaced
his experiment with brief but interest
ing lecture on the TRANSMISSION of blood.
The subjects upon which the operation
was performed were two dogs, one a good
sized mongrel, and the other a smaller
animal, having something OF the coach
dog in his composition. The professor
was assisted by some of the members of
the class, Mr.. Charles Carey having
charge Of the larger animal. The larger
dog was first held upon the table, and
after being put under the influence of
ether, the Professor proceeded to ex
pose the carotid artery. The apparatus
through which the TRANSMISSION was to be
effected was then produced. This con-
sisted of simple India rubber tube
about seven inches in length, and hav-
ing at each end brass nozzle with
stop-cock This tube was filled with a
saturated solution of bi-carhonate of
soda for the purpose of preventing the
coagulation of the first blood passing
through, and of also preventing the in
gress of air into the tube. One end Of
the pipe is introduced into the artery,
| and the animal laid aside, all the while
unconscious of what was going on. The
second dog then received attention, was
promptly anesthetized, and very soon
thereafter Professor Mason had laid
bare the .iugular vein. The other end of
the tube was inserted into the artery.
aud thus perfect tubular connection
established between the blood vessel of
the two animals. The stop-cocks re-
mained untouched, and the time for the
| more important use of the tube had not
yet come. If the small dog must have
blood from his larger and equally I'M
conscious neighbor, there must be rea-
son for it, and this was soon supplied.
In the second dog an artery was opened,
and his life-blood permitted to ebb rapi-
dly away. 1t continued TO flow till re-
| spiration ceased, and he was to all in
! tents and purposes a dead dog. When
the lungs had ceased to act; the flow of
| blood was instantly stopped, the stop
cocks attached to the tn bes that connect
ed the animals were opened, and the
blood was allowed to flow from the larg-
er dog into the smaller one which had
been exhausted by the hemorrhage.
simultaneously with this. artificial re-
spiration was induced by intermittent
compression of the thoracic walls, and
this was continued for a period of three
minutes, at the end of which time the
animal himself b,eathed and was pract-
ically restored to life. A few minutes
more and the flow of blood was stopped,
and the TRANSMISSION was complete. The
tube was removed, the ligatures were
deftly placed around the blood vessels
which had been severed, and, as the mar
cotic effects of the ether passed off and
the stimulating properties asserted
themselves, there were two intoxicated
CANNES, nothing the worse for the ex-
pertinent, to testify to the comparative
harmlessness of the experiment, and the
skill of the operator. Both animals
were doing we'll at last accounts, and the
Professor concluded his illustration by
instructing the students that before try
ing the experiment upon human beings
they should repeat it two or three times
on animals.
