1 put an omcc ot Sal Armomac^ into. 5 ounces of 
Spirit of Nitre, and the Liquor of the Thermometer de- 
fcended 2 inches 5 lines. This Mixture put forth fome Va- 
pours, vvliich fcen/d more confidcrable than thofe which 
do ordinarily exhale frcxn Spirit of Nitre alone. 
i poured half an ounce ot 6W/ xirmoniac into 3 ounces oiF 
Spirit of VitrioljWhich made a violen*: Fermentation. The 
. . Sjhjeft Matter was confiderably raiRdj and much Vapour 
went out, the Liquor was very thick, and the Tiicrmo- 
mxter defccnded 5, inches 6^ hues. I ©blerved, that the 
Vapouts which were raifed by this Mixture were Hot, and 
that they confiderably raifed the Liquor of the Thermo- 
meter, which Lheld hanging above the Subjed Matter, 
tho that which was dipp'd, within did defcend, and 
fliew'd a very great Cold. 
Sea Salt Sca- Salt mixcd with Acid Spirits, Heats the Liquors, in- 
txce^tjd, (^.^d (^jf Coohng them. 
Being mixed with Spirit ot Salt, it raifed the Liquor of 
the Thermometer fome lines, without (hewing anyfenfiblc 
Ferment, 
With Oil of Vitriol it ferments with a Noife, and raifes 
a great fmoke : the Liquor thickens, and becomes a fort df, 
a clear Jelly. The Liquor of tie Thermometer rifes very 
much in this Mixture, and the Heat is fenfibk to the 
Touch. 
yoiatiu^iU' the Volatile Alkalous/Salts mingled with different 
kus saitt ' Acid Liquors, excited a Ferment more or lefs ftrong, ac- 
w^giedwith cording to the Acidity of .the Liquors^ and the Purificati5 
■ prits. ofthefe Salts from their Fetid Oils. They all made., 
the Liquor of the Thermometer to defcend : but that 
which did fb the moft confiderably, is the Salt of Urine. 
One ounce of Volatile Salt of Urine very, well Redtified, 
in 4 ounces in Diftilled Vinegar, made a ftrong Fermen- 
, ration. The fubftance is elevated very much, and with 
apife and the Liquor of tha Thermometej: defcends in 
Vl^e F.erment oae inch 9, lines..
