EXPERIMENT XIII.

Whether Solvents dissolve Minerals, and cause that Heat observable in their Action, by any Antipathy betwixt the Mineral and the Men∣struum, or whether it did not rather proceed from the violent agitation of the parts of the Metal, either dissolv'd by the insinuation of its parts into the Pores of the Metal, or by obstru∣cting the passage of some aethereal Matter through those Pores, which wanting its usual course dissolves the Metal, by forcing a new way, I shall not undertake to determine; but having agitated Oyl of Vitriol with four times its weight of Water, thereby it obtained a sensible Heat; from which Experiment it ap∣pears, that the Heat produc'd by Minerals de∣pends not on a conflict of Acid and Alkalies, since Water is void of either of those chymical qualities.
