Thelaftfair^'puWifhed my Co^ Reafons. Of all thofe 
that have undercaken co combace them, there is not one that hath fo much 
as touched the ftace of the Queflion. And this hath made rae filent to them 
all. I have confined my felf to the experiments alOne • this,whereof I now 
fend you the particulars^ perhaps open tlie eyes to fome that are opin» 
niatre. I would not rrj i^^ the ftory but very plainly, without embarafling 
it by any raticclnr '-i : not but thst there was good matter to difcourfe 
upon, both dm: ne of tiicTransfufion, and after 
that thevomiting cuiiieircm the eating much Bacon, half an hour before 
the operation i Others, confidering the pain in his Kidneys during the 
TransOjiioiL c rdtheiwellingof hisStomack, which was prefently folio 
ed by evacuations aboveand below, do believe, that the new blood, entring 
in great quantity, caufed a plenitude, and a fermentation in the great vel- 
fels, which could not but be followed by all thofe effeds. To which may be 
added, that almoft all thofe^ into whofe veins other liquors then bioud have 
been j>;/^f^,have found the fame Accidents. / 
Itjis alfo not yet agreed on, what was the caufe of the fallitude, that ob- 
liged this man to keep his bed for fome whole dayes : Some fay, it proceed- 
ed from the diforderconfequent to the entry of new blood into his veins. 
Others have lookM upon it as the effed of a kind of Rhutnatifme he had 
got,lying ftark naked in the ftreets and have thought that he became noc 
lenfible of thofe pains, but after the recovery of hisreafon,)uft as thofe that 
Jiave a hot Feaver do never complain of wearinefs, but after the abatement 
of the Fitt. 
There hath alfo been very differing Difcourfe of that tor/^colour in hig 
Urine fome r^ayes 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, difcharging it felf by the veins, and which being re- 
tained before^ fent up vapours to the Brain capable to trouble the fundions 
thereof. 
f?- 1 fliall 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 Recipienc 
animal piffedbloud after it, and as far as T 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 fuccefs. But we need not repent for not having obferved 
them in this cafe ; it appeared much better what the Transfufion all alone
