the indudion is falfe, that there is ho Acid in {^int of 
Wine, {\x\z^ Acids do generally, if not always hinder the 
fermenting of bodys. 
To the fth, he anfwers, that fpirit of Wine digefted 
with Syrup of Violets, will change the colour. 
Dr. Vhight having thus far been upon the Negative, 
by declaring what fpirit of Wine is not, i he now afferts 
it to be an oyl, which is ardent or inflammable, by no 
means upon the fcore of its Volatile fait, for then fait 
of urine muft burn j nor upon the account of any Acid^ 
which has been already refuted 5 much lefs upon the ac- 
count of its water and Earth, for that were abfurd ; ergo 
ratione Olei, He gives an Inftance how fpirit of Wine 
may be reduced to a true oyl , for as it is a fpirit, he fays 
it has only loft the outward form and confiftence of oyl, 
being made more fine and lub tile, yet notwithftanding, 
he propofes a way to bring it to oyl again. Take a 
quantity of high fpirit of \Vine, put it into a Cucurbit, 
which is not very well doled, let it ftand for j months, 
then endeavour to re(3:ify it in a gentle Balneo^ you will 
find little fpirit that will rife,but a good quantity of in- 
flammable oyl will remain at the bottom. 
Mr. Kun\els anfwer does principally confift in deny- 
ing the experiment, of deducing fpirit of Wine to o}il,by 
the way and method propofed, or by any other: unlefs 
he perhaps firft united fome oyl with his fpirit,and then 
the Air having fublimed the fpirit, which was lighter 
then the oyl or water, by this means perhaps, he obtain- 
ed fome little oyl. 
Dr. Voight examines an EpiftleofMr. Kun\els^ fent 
to him for that purpofe. 
The firft Prsefuppofition of the Author of the Epiftle is, 
that all Vegetables contain an Acidum & Vrinofum. The 
2d. that all Fermentations produce Acids^ which are 
fcparableby Art. 
In anfwer to the firft, Dr. Voight complains of his
