Note 11 — OF THE Malignant and Petechial FEVER.

It is long since the Peruvian Bark has been used by Practitioners in Malignant Disorders, though I do not know that any body gave it in this Fever to the Amount of an Ounce per Day, before Dr. Haen and Dr. Hasenohrl. Dr. Ramazini mentions its having been tried in the Petechial Fever, in the Years 1692, 3, 4. And in a Treatise on the Plague in the Ucrane, published at Petersburgh, in the Year 1750, we are told, that in the French Translation of the Philosophical Transactions for the Year 1732, there is a Note to p. 264, telling, that Mr. Amyand informed the Academy of Surgery at Paris, that Mr. Rushworth, Surgeon, had wrote to Sir Hans Sloane, on the 23d of May 1723, that when he was Surgeon to a Ship, in the Year 1694, he had cured some Men ill of the Malignant Fever, attended with pestilential Buboes, by means of the Peruvian Bark. Dr. Huxham has recommended a Tincture of the Bark; and Dr. Pringle, a strong Decoction of it, with some of the Tincture, in these Malignant Fevers.
