h'j ptting into it a little Aqua fortis, or Oylof Vitriol, or Spirit of 
Salt, (thefe being the mop; ufual Add Menflruums,) the Blood not 
only would prefently loofe its pure colour and become of a Dirty one , 
hut in a trice he alfo coagulated ; whereas if fome fine Vrinous fpi- 
rit^ abounding in Volatil Salt^ fuch as the Spirit of Sal Armoniack , 
rv ere mingled with the warm Bloody it would not only not curdle it^ or 
imbafe its Colour^ hut make it look rather more florid than before, and 
both keep it fluid) and preferve it from Futref action for a long time. 
This xperiment I devis'dy among other things to fljew the Ami- 
cd}o\Qm(s of Vo\m\ fpirits tothe^XooA* And I remember 'twas 
fon^uch taken notice of^ that fome very Inquifitive Members of^the 
Sodtiy came prefentlytome^ and de fired me to acquaint them more 
particularly with it 5 which I readily did) though afterwards I made 
fome further obfervations about the fame Experiment^ that I had no 
occafion to relate* 
This having been fo public kly done, though I Jha/I not fay ^t hat Sig- 
ner Fracaflati may not have hit) as weUas /, upon the Experiments 
fubltfhed in his Name^ yet there is fo 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 imperfect Rumor of 
our Experiment without knowing whence it came^ ana fo maj^ without 
any dis ingenuity ^have thence taken a hint to make and publijh^what now

fome other Circumjlances belonging to it. For I remember^ 1 tryed 
it with other Liquors (^j Spirit of Wine, Oyleof Tartar,; Oyle 
of Turpentine^) and I think alfo^ I can fend you fome remarks upon 
the Colour of the upper part of the Blood. And Ijl^all on this occa- 
fion add in reference to Anatomical matters in general, th&t after I 
fawy how favourably the Ufefulnefs of Experimental Philofophy 
was receiv' I was invited to inlarge it in another Edition 5 and for 
that^ I provided divers Anatomical as well) as other Experiments) 
and de(ign d many more, fo that I have by me divers things ) that would 
not perhaps be unwelcome to Anatomifts, c^r.
