Seed predominating above that of the Mother, the Conftb 
tution of the Foetus is very different from her’s that bears it, 
although nourifht by the transfufion of her blood. 
2. The Transfufion of blood is but a very compendious 
way of the continual transfufion of our Aliments, which is 
alfo taught us by Nature after our birth. For , whereas the 
Meats which we eat for the reparation of our ftrength , and 
refreihra^nt of the heated parts, have very many impurities 
mixt with their good juices, which muft be concocted by the 
heat, and.digefted in the acid Liquor of the Stomach ; which 
done, the purer portion of the fame digefted juices is con- 
verted into Chyle, that Chyle impel!’ d into the Veins to be 
mingled with the Bfood, convey'd therewith to the heart, and 
there receive its utmoft perfection} The Transfufion of blood 
is made more fpeedily, and with much more efferft, fince 
thereby, in a very fmall time, a moft elaborated Liquor is 
immitted immediately into the Veins , where it inftantly re- 
dreffeth fuch defeats as it findeth in the internal parts , when 
they are diftempeivd* 
Phyfitians cannot deny, That the greateft part of our 
Difeafes are but Refults of the Diftemper and Corruption of 
the blood, fince the fpeedieft and commoneft remedy they 
have inPraCtice, is, to evacuate the fame by Phlebotomy, or 
elfe refrefh and cool it by Juleps-. But they muft alfo confefs,. 
That whilft they endeavour to draw out the Corruption^they 
at the fame time diminifli the ftrength and vigor, and that 
great Fevers by this means are oftentimes follow’d by Faint- 
neffes and Dropfies: On which confideration , fome Phyfici- 
ons fpare bleeding as raucbas poflibly they can. Moreover, , 
it muft be acknowledged. That Drinks palling through the 
Stomach and Inteftines, before it arrive at the Veins and Ar- 
teries, to be mingled there with the bloody they may be al- 
ter’d a thoofand waies by the Ferments occurring in the paf- 
fage, or elfe they may caufe fome alteration in thole parts by 
Ferments accompanying them, and fo leave weakneifes and 
dangerous Crudities behind them. But in Transfu/ion all 
thefe things are avoided, and all Phyfitians brought to agree- 
ment within a fliort time. They who are for blood-letting.*
