tion together. To this reafon the Dodtor gives no credit, 
for he fays, fpirit of Ni ere is as pure as that of Vitriol, and 
that with fpirit of Wine, they doe make an alteration: 
and the higher they are, the more they heat, but if very 
Jiighly rectified, they will produce flame upon their mix- 
ture. 
Mr, ^mkel fcQms to hQ in no wife of his judgment, that 
the mentioned ^ad fpirits, are of an equall purity ; he 
thinks, in that of Nitre, there is lome thing ot an Vrino' 
fum ; in the oyl of Vitriol, none at all. As to the expe- 
riment oi flame, produced by oyl of Vitriol, and fpirit of 
Wine, he tells him, that he read it out of an Author, but 
it never fucceeded. 
Since fpirit of Wine is an oyly body, the Author of the 
Letter, makes a queftion, how it comes to pafs, that it 
makes no ebullition, and gives no colour to any fpirit, 
except that of Nitre > to which Dr. Voight anfwers, be- 
caule it caufes no more ebullitions, for that reafon, it 
approaches the nature of oyls- for Acidumb^ Vrinofum^ 
does only excite thofe ebullitions. He anfwers further, 
that it does indeed make ebullitions, both with fpirit ot 
Nitre, and of fait, but that it does fo, by reafon of an X;- 
irinom{2Ax,, itcontains. 
To this Mr. IQinkel thinks, he has copioufly anfwer-* 
cd, and therefore fuperfedes. - ' 
IntheEpiftile, Dr. Voight anfwers, to this objedtion,; 
that if fpirit of Wine vfttQ2inOleo/um, why it would not 
mix with oyl : he anfwers it, by proving the contrary, 
that if you put into high redified fpirit of Wine, oyl of 
Fennel, or Annifeeds, it will difTolve. Um tol 
Mr. J5^«>^^/ reply s, that it retains fome few dro'p^of 
this oyl, by reafon of that f mall ofiginlxtj Jddum irP 
the fpirit 5 but if you impregnate it with more falts, itf 
will take up, and diifolve more oyl. Alfo that iteafilj?}
