On avait très anciennement remarqué qu'en mêlant ensemble de l'acide muriatique et de l'acide nitrique il en résultait un acide mixte, qui avait des propriétés fort différentes de celles des deux acides dont il était composé. Cet acide a été célèbre par la propriété qu'il a de dissoudre l'or, le «roi des métaux» dans le langage alchimique, et c'est de là que lui a été donnée la qualification brillante d'eau régale. Cet acide mixte [...] a des propriétés particulières dépendantes de l'action combinée de ses deux bases acidifiables, et nous avons cru, par cette raison, devoir lui conserver un nom particulier.
