An intetestin. experiment, involving the traus.

tho presence Of tho students Of tho college. The
or Of PhyEolo5y. who prefacea his experiment
with brief but interesting lecture on tho
TRANSMISSION of blood. file subjects upon which
tho operation WAS performed wezo two dogs, ono
good-szed mongrel aud tho other smaller
animal, having Bomething Of tile coach-dog in
his composition. The Professor MAS assisted by
sotne OF the members OF tho class, Slr. Charlea
Carey having charge OF tho larger anlmAl Tho
larger dog Was first held upon tho table, and
after being put undcr tho influence Of ether, tho
Professor proceeded ta expose The carotid arterv.
Tho apparatus through which tho translation

sisted OF simple India-ihbber tube about
inches In longth ana having ak each ena d hrasa
With saturated solution OF bi.caEbonnte Of soda
Iur tho purpoae Of preventing the coagulation Of
tho first blood passing through, and Of 4l.o p1o-
yout!ng tho ing1esa Of air Into the taLe. One
end Of tho pip0 wns introduced iuto tho artery,
and tho animal laid aside. all tho while uncon-

como. II the small dog must have blood from
hls larger and equally unconscious pefghbor,
thete muat be reason for 1t, aud this WAS soon
supplied. In tho secund dog an artery was oreu-
ed, andhis iife-blood Was permitted to ebb 1apid-

ceased, and he WAS to ali intants and purposes q
