To apply the Experiment. In the Cold Fit of an ^^ub 
wehave often a ftrong and quick Poifo which argues an 
Ebullition (tho I dare nor call it an Efferv^fcence^ and 
quick motion of the Blood, and the pains of ihe head and 
other parts may be due^ co toogreat diftrefs orextenficn 
of the Veffels* which depends on the expanfion of the 
boyhng humours. In this artificial tho^^?/i mixture we 
©bferve, a mighty commoiion and high Ebullition and 
^ expanfion cf the Liquor. In the Bkod and othtx Juices of the 
body we conftanily difcover great quantities of volatile 
Salts ^ and fometimes either from an infefted Jir^ or bad 
dyet^ and from feveral t)ther taufeS5 foury^/^^j- may be de- 
rived to the bloody which may a<5t: upon thefe volatile SaltSj^ 
the blood fe much abounds with, as to give a notable fenfe 
- of cold, Itisno new thing for us to meet with Patients.^ 
that have thrown Mponxhtir Stomacks Bowels (which 
arc the great £'/;2//;2Sot>^ of the Blood) vQX^ four Liquors,^ 
iiich as when they happen to fall upon the T>6'/f/> will cor- 
rode thofe hard parts. Thus in our £"A;/?m>?2^;2^ tisplainthat 
a forrtign acid meeting with a volatile Salt drawn from the 
bloody does produce a cold effeB \ and fince we know no 
Liquors but a mixture of this -^Wchat gives us fuch a cold 
Phienomem?i> it feems not unreafonable to believe thatthe 
£old Fit of an y^gue may be due to Gich 'd mixture. 
As to the Incalefcence made in our mixture, I ftould 
have told you that it was done by the bare addition or 
fome drops of Oil of Sulphur per Campanam^ being a Liquor
