ts So much In an lcxpianato

OF an interesting experiments -inSoaxing
Che TRANSMISSION OF blood which mas
made ut the Buffalo Medical College,
yesterday afternoon. at 2 80 o'clock. in
the presence Of the students Of the col
lege. The operator was VIM. II. Ma
son, N. D, Professor Of Physiology,
who prefaced his experiment with brief
but interesting lecture on tue TRANSMISSION
of blood. The subjects upon which the
operation was performed were wodogs,
ones goodsized mongrel and the otter
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 6rst laid upon the
table, and after being put under the in
fiuence of ether, the Professor proceed
cd to expose the carotid artery. The
apparatus through which the tranfusion
was to be effected was then produced
This consisted Of simple India,rubber
tube about seven inches in length and
having at esch end brass nozzle with
stop-cock. This tube was filled with
a saturated solution of bi carbonate Of
soda for the purpose OF preventing the
coagulation of the first blood passing
through, aud OF also preventing the 10.
g-ess of ali. into the tube. One end OF
the pipe was Introduced into the artery,
and the animal MAS laid aside, all the
while unconscious of what was going
on. The second dog then received at
teDtion, was promptly an@sthetized, and
very soon thereafter Professor Mason
had laid bare the jugular vein. The
other end of the tube was inserted into
the artery, and thus perfect tubular
connection established between the
blood vessel of the two animels. The
stop cocks remained untouched, and the
time for the more important use of the
tube had not yet come. II the small
dog must have Llood from his larger
and equally unconscious -neighbor, there
must be a reason for it, and this was
soon supplied. In the second dog an
artery was opened, and his life-blood
was permitted to ebb rapidly away. 1t
continued to flow till respiration ceased,
and he was to all intents and purposes
dead dog. When the lungs had ceas-
cd to act, the flow Of blood was instant
ly stopped, the stop,cocks attached to
the tubes that connected the animals
were opened, and the blood was allowed
to flow from the larger dog into the
smaller one which had been exhausted
by the hemorrhage. simultaneously
with this artificial respiration was indu-
ced by intermittent compression of the
thoracic walls, and this was confined
| for period of three minutes, at the
end OF which time the. animal himself
breathed and was practically restored to
life. A few minutes more and the fow
Of hood was stopped and the transfu
sion was complete. The tube was re-
moved, the ligatures were deftly placed
around the blood vessels which ,haG
been severed, and,as the narcotic effect:
| of the ether passed off and the stimula
Ting properties asserted themselves, there
were two intoxicated CANNES, nothing
the worse for the experiment, to testify
to the comparative harmlessness Of tht
Z experiment and the skill of the opera
tor. Both animals we're doing we'll 3
last accounts, and the Professor conclu
1ded his illustration by instructing tn,
b students that before trying the expert
ment upon human beings they shoult
repeat It two or three times on animals
