figne) upon Blood yet warm, as it came from the Animal, viz.*' Thai 
by putting into it a little Aqua fortis, or Oylof Vitriol, or Spirit of 
Salt (the fe being the mofl ufual Acid Menftruums,) the Blood not 
only would prefently loofe its pure colour and become of a Dirty one 
but in a trice be alfo coagulated >, whereas if fome fine Vrinous fpi- 
rit , abounding in Volatii Salt, fuchas the Spirit of S al Armoniack 
were mingled with the warm Blood > it would not only not curdle it or 
imbafe its Colour , but make it look rather more florid than before, and 
both keep it fluid, andpreferve it from Put refaction for a low time. 
This xperiment I devis'd, among other things to flew the Ami- 
cablenefs of Volatii [pints to the Blood. And I remember ’twas 
[6 much taken notice of, that fome very Inquifitive Members of the 
Society came prefently tome, and de fired me to acquaint them more 
particularly with it 5 which I readily did, though afterwards I made 
fome further obferv at ions about the fame Experiment^ that / had no 
occafionto relate. 
This having beenfo publickly done, though I flail not [ay, that Sig- 
nor Fracaflati may not have hit, as well as I, upon the Experiments 
publifled in his Name, yet there is [0 little difference between the 
warm Blood of an Animal out of his Veins and in them, that \ tis 
not very improbable, that he may have had fome imp erf eel Rumor of 
cur Experiment without knowingwhence it came, and [0 may, without 
any dis ingenuity y have thence taken a hint tomake and publifl, what now 
is Englifl’d in the T ranfadtions. if it be thought ft, that any menti- 
on be made of what I related [0 long fmee, I think, I can [end you 
fome other Circumflances belonging to it. For 1 remember, I try ed 
it with other Liquors ( as Spirit of Wine, Oyle of Tartar, Oyle 
of Turpentine,) and I think alfo, I can [end you fome remarks upon 
the Colour of the upper part of the Blood. And / flail on thisocca- 
fionaddin reference to Anatomical matters in general, that after I 
[aw 0 how favourably the Ufefulnefs of Experimental Philofophy 
was receiv’d , I was invited to inlarge it in another Edition • and for 
that, I provided divers Anatomical as well, as other Experiments, 
and defgn d many morefo that 1 have by me divers things, that would 
not perhaps be unwelcome to Anatomifts, &c.
