All Account of an easier and safer Way of Transfusing Blood out of 

 one Animal into another, viz. hy the Veins, without opening any 

 Artery of either. By Dr. Edmund King. iV" 25, p. 449- 



1 . I took a calf and a sheep, both of the larger sort, and having prepared a 

 jugular vein in each, I planted my pipes and quills as is usual, both in the jugular 

 vein of the calf designed to be the emittent, and in that of the sheep intended 

 for the recipient. Then I took out of the sheep 49 ounces avoirdupois of bloody 

 before any other blood was let in ; about which time the company concluding 

 the sheep to be very faint, and finding the blood to run very slowly, I stopped 

 the vein of the sheep, and unstopped the pipe in the calf, letting run out 10 

 ounces into a porringer, which was done in about 40 seconds. Then I con- 

 veyed pipes from the emittent calf s vein into the recipient sheep's vein, and 

 there ran a good free stream of blood for the space of five minutes, though per- 

 haps less swift than the first ten ounces. And not to be deceived in the run- 

 ning, I often struck with my finger the upper part of the emitting vein, and 

 thereby easily felt every stroke answered on the recipient vein, just like a pulse. 

 And now supposing that by this time (the lapse of five minutes) the sheep had 

 received as much if not more blood than it had lost, we stopped the current of 

 blood from the calf, and closed also the vein of the sheep ; and then having 

 untied her and set her down in the room, she went about, and appeared to have 

 as much strength as she had before the loss of her own blood. Then resolving 

 to bleed the sheep to death, we bound her the second time, and opened the 

 emittent part of the vein again ; whereupon having bled about 60 ounces, she 

 fell into convulsions; and after the loss of about five ounces more, she died 

 upon the spot : and being dressed by the butcher, there did not in all the usual 

 places appear above three ounces of blood ; and the whole sheep looked of a 

 lovely white ; and the meat of it (to the taste of those that eat of it) was very 

 sweet. 



The sheep being dead, we resolved likewise to see the calf bleed to death ; 

 but he having bled ten ounces, and then for the space of five minutes more into 

 the sheep, and rested a good while, the blood by that time began to coagulate 

 in the vein ; which made me open the carotid artery, letting thence run out 

 about 25 ounces of blood of a very vivid colour, vastly excelling therein the 

 blood of the vein. The calf when dressed had by the information of the butcher 

 as little blood as the sheep ; and we saw him look whiter than they usually do 

 in the ordinary way of killing. 



2. I took more than 43 ounces of blood out of the jugular vein of a sheep.
