1 3. I do not fee, by comparing the Weights 
of thefe Animals, and the feveral Qiianticics of 
Blood which pafs thro' their Hearts in a giv- 
en Time, that we can thence form any Rule 
that is fixed, for the proportioning the (Quanti- 
ties of flowing Blood to their different Sizes, 
14. Thefe Quantities in larger Animals are 
very difproportionace to the Bulk of their Bo- 
dies, in cbmparifon of what they are in leffer 
Animals, as eftimated in this Table. 
1 5. But as in the bigger Animals the Blood 
has a longer Courfe to go, and mufl: therefore 
meet v/ith a greater Refifl:ance ; fo we may 
obferve in this Table, by comparing the per- 
pendicular Heights of the Blood in the Tubes 
fixed to the Arteries, that the Force of it in 
the Arteries, is in the main greatefl: in the 
largefl: Animals. 
16. And fuppofing the Blood-veflTels in the 
Man and Horfe to be equally diflributed in all 
their homologous Parts, that is if they are 
proportionable to their refpedive Weights, 
then the Blood muft move in them recipro- 
cally as the Times, in which CJuantities of 
Blood equal to their refpeftive Weights, pafs 
thro' their Hearts, viz* as 60 to 15.15 Mi- 
nutes.
