The Room in the Dragon Volant

The curious case which I am about to place before you, is referred to, very pointedly, and more than once, in the extraordinary Essay upon the Drug of the Dark and the Middle Ages, from the pen of Doctor Hesselius.

            This Essay he entitles Mortis Imago, and he, therein, discusses the Vinum letiferum, the Beatifica, the Somnus Angelorum, the Hypnus Sagarum, the Aqua Thessalliae, and about twenty other infusions and distillations, well known to the sages of eight hundred years ago, and two of which are still, he alleges, known to the fraternity of thieves, and, among them, as police-office inquiries sometimes disclose to this day, in practical use.
