from an Elfential Acid Salt 
mix’d with fome Oily 
parts, whereof it confifts ; 
for, if you feparate thefe 
two iubftances, one from 
another, neither of the two 
will prove at all fweet : 
The Oil alon6 is infipid 
upon the Tongue, becauie 
it makes little or no Im- 
preHidn upon the Nerve 
that ferves for Tailing ; 
but when the Acid is en- 
tirely mix’d with it, the 
Edges of this Acid do ferve 
for a Vehicle to the Oil, to 
makfc it penetrate and tic- 
kle fiiperficially the Nerve, 
whereby the fenfe of Tail- 
ing is produced : The Acid 
therefore being alone, does 
become incilive, and pricks 
the Tongue -by its Edges ; 
but when they are dull’d 
and blunted by the Ramous 
parts of the Oil, then they 
have another fort of Deter- 
mination, and can no longer 
pierce the Nerve of Tail- 
ing, but with a great deal

better for Coughs than 
common Sugar, becaufe , 
being harder, it requires a 
longer time to melt in the 
Mouth; and befides, it 
keeps the Breaft moifter 
than the common Sugar. 
Spirit of Sugar is made 
fin the following manner : 
powder and mix eight 
Ounces of White Sugar- 
Candy with four Ounces 
ofSal-Armoniack ; put this 
Mixture into a Glafs, or 
Earthen Body, whofe third 
part only is thereby fill’d ; 
fit an Head to the Body, 
and place it in a Sand-Fur- 
nace ; join a Receiver to 
it, and lute well the Jun- 
dlurcs with a wet Blad- 
der ; give it a fmall Fire 
for an Hour only, to heat 
the Veflel ; then increafe it 
to the fecond Degree ; there 
will dellill a Liquor, Drop 
by Drop, and towards the 
End there will rife white 
Vapours into the Head ; 
increafe your Fire Hill 
more, until nothing more 
comes forth ; let the Veflels
