long preferve its Purity and temperament • in regard that up* 
on its Arrival at the Liver ( which is the grand Organ of San- 
guification wherein the blood receives all us qualities/it would 
infallibly lofe all its goodnefs, and in an inftant become like 
the whole Made, which we fuppofe corrupted > and confe- 
quemly can produce no benefit therein by its mixture. 
But this 'Objection is ill enough grounded, fince it fuppof- 
eth the blood to be made in the Liver, and is contrary to ex- 
perience which demonftrateth moft evidently, both the exi- 
stence of blood in Animals before the formation of the Li- 
ver 9 and alfo the Arrival of the Chyle, and at the heart, and 
converfion of the fame into blood there, before it entreth in- 
to the Veines which carry it to the Liver: wherefore I difmifs 
this reafon and proceed to another, which feemeth ftronger 
and is offer'd by perfons more judicious. 
5 I is not contefted in this Objection in what place fanguifi- 
cation is perform’d, becaufe ’tis held to be done in feveral 
parts of the body, namely by reiterated circulations in the 
heart , V eines and Arteries : But ’tis like wife maintain’d that 
all.thefe parts come either by ficknefs or age, to a certain de- 
gree of intemperature and malignity, from which there is no 
potfibility to recover them ; and that in this ftate they have 
power to communicate their evil qualities to whatfoeverap- 
proacheth them} whence eonfequently in a little time they 
corrupt the laudable blood, wherewith they are newly irriga- 
ted. Proof of this is afforded both by example and experi- 
ence. The example is taken from a Hoglhead offline gar , 
which being once throughly imbu’d with that Liquor , is no 
longer fit to contein any other, but every thing pour’d there- 
into is immediately infected with fowernefs by contagion of 
the Cas\e. The experience confifts in that which was lately 
publifht by an Englifh Doctor, who trausfufing the blood of 
a Mangie Dog into a found one, to try whether the Mange 
would be communicated with the blood, found the Mangie 
Dog cur’d , and the other who had receiv’d his blood not to 
become Mangie.
