“Schroder thinks that in what Pliny says of Flos Salis, he can find the martial sal-ammoniac flowers of our chemists, [the double chloride of ammonium and iron], or the so-called flores sales ammoniaci martiales.—It is certain that what Dioscorides and Pliny call flos salis, has never yet been defined. The most ingenious conjecture was that of Cordus, who thought that it might be Sperma ceti; but though I should prefer this opinion to that of Schroder, I must confess that, on the grounds adduced by Matthiali and Conrad Gesner, it has too much against it to be admitted as truth.”—Beckmann, Hist. Inv. Vol. II. p. 193. Bohn’s Ed.
