Percolation of the blond of Animals, whereby that of the one 
ffio||ld be changed into the nature of the other. 
3. The mod: probable ufe of this Experiment may be con- 
jectured to be, that one Animal may live with the blond of 
another $ and conlequently , that thofe Animals, that want 
bloud, or have corrupt bloud, may be liipplyed from others 
with a fufficicnt quantity, and of fuch as is good, provided the 
Transfuffon be often repeated, by reafbn of the quick expencc 
that i s made of the bloud.
