mble to exped a more conftant Accenfion from the A- 
nimal Oyls than from any other. 
Olenm Succini is jullly put in the Catalogue of Mi- 
nerals, and is produced by a ftrong degree of Fire (as 
is above mentioned ) does yet not make any Motion , 
and fcarce any Incakfcence with this Oyl,notwith{land- 
ing its abounding with Volatile Salts: The reafon is, 
becauft thefe Saks are not properly Volatile, as Alkalies 
arc, but do belong to the Family of Acids, and fo can 
make no Ferment with this Compound Spirit, which is 
it felf highly Acid. 
Having now made it plain and eafie for any one to 
make two Liquors, aftually cold, without any adven- 
titious heat or fire, boyl up to a Flame, it will feem 
ftrange that after fo many Experiments made in the 
World by all forts of Ghymifts, and with all manner of 
Fermenting and Fiery Ingredients, none Ihould have 
difcovercd a certain way of producing this great am^ 
defirable Effed:. For though I will not queftion the 
veracity of the %ttzX. Borichius ^ who declares to the 
World, that he made his Oyl of Turpentine and Spirit 
of Nitre to take Fire and Flame ; yet for my part, after 
fo many unfuccefiful Experiments made with the great- 
eft Accuracy I could, I muft ft ill own my incapacity 
to perform it: But if you add fome drops of Balfam 
of Sulphur to that Oyl of Turpentine, the Effea will 
then very certainly fucceed, and your Mixture advance 
to an aftual Flame. However it may prove as to this 
laft mentioned Mixture, the great variety of other Li- 
quids that are made to kindle and produce flames, will 
now put the Matter of Fad: out of Queftion, which I 
am told has been by many Experimentors doubted of.
