as ufe to do the Carotidal Artery of the MidmmAmml ] not 
designing any thing further, than to determine by Experiment the 
Infection of the Recipient's blood. Then I made as ftrong a Li- 
gature upon the Dogs Neck , as 1 durft , for fear of choaking him, 
to the end , that the Vend blood , which is much more fluggilh in 
its motion and evacuation , than the Arterial , might be emitted 
with the greater advantage of Impetus. 
Then I took a ycung Land- Spaniel , of about the famebignefs, 
and prepared his Jugular Vein , as is ufually done in the Recipient 
Animal *, the heart-ward part of the Vein to receive the Maingy 
Dogs blood, and the head-war dy>zxto£ it to difcharge his own in- 
to a Dife. 
Having thus prepared them both , and placed them in a con- 
venient pofture one to theOther, I let flip the running knots , and 
by frequent comprefldon of the Neck (befides the Ligature I 
liad made ) by reafon of the tardy running of the Venal blood 
out of the Eminent , transfufed about 14 ox 16 ounces of the 
blood of the Infected, into the Veins of the Sound Dog , as neer 
as I could guefs by the quantity of blood , which ran into a 
Difh from the Recipient 5 fuppofing the Recipient Animal to 
lofe near about the fame proportion to what the Eminent fup~ 
plies. - ■ ■ :L ; ' f ; f ! Ji ' . 
The effedf of which Experiment was , no alteration at all ^ any 
way, to be obferved in the Sound Dog. But for the Maingy Dog ? 
he was in about 10 day es or a fortnights fpace perfectly cured' : 
which might with probability enough , I think, have been ex- 
pected from the confiderable evacuation, he made 5 ( perhaps the 
quiekeft and fureft remedy for the cure of that fort of difeafe, he 
wasinfe&ed with , both -in. Man and Be aft.)
