The lafl: year I 'publiflhed mV Conjectures and my Reafons. Of all thofe 
shat have undertaken to combate them, there is not one that hath fo much 
as touched the ftate of the Queftion. And this hath made me Client to them 
all. x have confined my felf to the experiments alone ^ this, whereof I now 
lend you the particulars, will perhaps open the eyes to fome that are opitl- 
niatre. I would not relate the ftory but very plainly, without embarafling 
it, by any ratiocinations-, not but that there was good matter to difcourfe 
upon, both during the time of the Transfufion, ana after it. Some believed, 
that the vomiting -came from the eating much Bacon, half an hour before 
the operation : Others, confidering the pain in his Kidneys during the 
Transfufion, andthefwellingof his Stomack, which was prefently follow- 
ed by evacuations above and below, do believe, that the new blood, entring 
in great quantity, caufed a plenitude, and a fermentation in the great vef- 
fels, which could not but be followed by all thofe effects. To which may be 
added, that almoft all thofe* into whofe veins other liquors then bloud have 
been injetted , have found the fame Accidents. 
Itfis alfo not yet agreed on, what was the caufe of the k/fitude, that ob- 
liged this man to keep his bed for fome whole dayes : Some fay, it proceed- 
ed from the diforder confequent to the entry of new blood into his veins. 
Others have look’d upon it as the effe& of a kind of Rhumatifme he had 
got,lying fiark naked in the ftreets ^ and have thought that he became not 
fenfible of thofe pains, but after the recovery of his reafon,juft as thofe that 
have a hot Feaver do never complain of wearinefs, but after the abatement 
of the Fitt. 
There hath alfo been very differing Difcourfe of that black. colour in his 
Urine fome dayes after the Transfufion ^ fome alledging, that it was caufed 
by fome veins, which having been opened from too great a fulnefs, dif- 
charged themfelves into the Kidneys and Bladder • others, believing that 
it was a black choler, difeharging it felf by the veins, and which being re- 
tain’d before, fent up vapours to the Brain capable to trouble the funCUons 
thereof. 
I Hi all here fufpend my judgment, refolved not. to declare my thoughts, 
till I have made many experiments more, For I know very well, that in 50* 
we have made upon Brutes, we have found it but twice that the Recipient 
animal piffed bloud after it, and as far as I can judge, I believe I have 
infallible wayes of preventing all fueh diforders ^ and I have propofed to 
my felf a manner of preparation aud treatment, which the Patient may be 
made to obferve both before and during the operation, to render it more 
beneficial. For *tis not to be doubted, but meafures are to be taken to dif- 
pofe the body for Transfufion, as well as for all other operations to be un- 
dertaken with fuccds. But we need not repent for not having obferved 
them in this cafe ; it appeared much better what the Iransfufion ail alone
