Note 105 — Chapter XXXI

(1, 2) Dr. Tissot informs me, that in Swisserland, they call a volatile Salt of Vipers, or the volatile Salt of raw Silk, Sel. d'Angleterre, of which one Goddard made a Secret, and which he brought into Vogue the latter End of the last Century. But he justly observes at the same Time, that on the present Occasion every other volatile Alkali will equally answer the Purpose; and indeed the Smell of some of them, as the Spirit of Sal Ammoniac with Quicklime, Eau de Luce, &c. seem more penetrating.
