A discourse denying the præ-existence of alcalizate or fixed salt in any subject, before it were exposed to the action of the fire: To which is added a confirmation of an assertion, deliver'd in numb. 101. p. 5. q. 6. Of these tracts, viz. That alcalizate or fixed salts extracted out of the ashes of vegetables, do not differ from each other: The same likewise affirm d of volatil salts and vinous spirits; by the learned Dr. Daniel Coxe
Abstract
The Alcalizate or Fix'd Salts of Plants, extracted out of their Ashes Incineration, or out of Tartar calcined, do, in my apprehension, neither præ-exist in the Vegetables that afforded them, before they were expos'd to the action of the Fire; nor do they differ considerably, (I am certain, not sensibly) from each other.
