may be greatly beneficial to the Blood, as 
well as by reftifying its Crafis in mixing 
with it as a Menftruum. Thus the Cortex is 
in a double Capacity an Attenuator, both by 
reftringing the Veffels, and alfo by diluting as a 
Menftruum the Fltiid of the Blood, which it 
is well known to do, when mixed with extra-

with the Blood as a Menftruum, as it does 
when mixed with cold Water 5 but to this alfo, 
that at the fame time that it gives a contrac-

between the contraded Veffels and the more
