Juthor conjefttireth, upon this account^ that

Blood of the Eminent , as confiding of parts difproportionate 
to his own. But , as has been already obfcrved , his Entrails 
were altogether vitiated by a Gangrene^ and he therefore out o{ 
the reach of being relieved by this Experiment. 
Concerning the other inflance^ viz. of the Dogg, the Let^ 
ter affirms 0 that that Tryal was made by Monfieur G^yen with 
great exadnefs; after this manner. He drew three great difhes 
of Blood from the Dog that was to receive, and weighed the 
other Dog that was to furnifli 5 and, the operation being per- 
formed, he weigtied him again, and foimd him wei^h lefs-than 
he did by ttvo pounds ^ of which, having abated an atf^ce more 
orlefsj for the Urine, made by the Dog, and an omceox trvo more 
for the Blood fpilt rn the Operation, there remained at l^diikone 
pound and a hdf of Blood, that was transfufed. But, the Re-

the Imittent being yet alive. Whence it feems evident to this

dominant over the Native^ and, as 'twere, overwhelmed it. 
Whence he again inculcates the dangerouCnefs of infufing t^o
