Note 17 — OF THE Malignant and Petechial FEVER.

Riverius tells us, that, according to Hippocrates’s Doctrine, Deafness is a very dangerous Symptom in the Beginning of acute Disorders, though it be a good Omen, and portends Health, when it does not appear till the Height of Fevers, especially those of a malignant Kind; and adds, that he himself has a thousand Times observed, that those labouring under this Fever have recovered, when this Symptom of Deafness came on at the Height (in statu) though the other Symptoms threatened much Danger. Prax. Medic. lib. XVII. sect. iii. cap. i. p. 451.

This Symptom of Deafness occurs in other Fevers as well as in this, and often proves a good Symptom in them likewise, as I have frequently observed. Two remarkable Examples of which I had under my Care in St. George’s Hospital, in the Year 1759. On the 17th of January 1759, James Donaldson, a young Man of nineteen Years of Age, was admitted into the Hospital for a Fever, attended with a Stupor and a Delirium, a parched dry Tongue, and other Symptoms of a Fever of the inflammatory Kind, for which he had been blooded, and used other Evacuations. On the 19th, after the Application of a Blister, he was seized with almost an entire Deafness; after which, all his other Symptoms became milder, and he mended daily, and was entirely free from the Fever by the 30th. On the 10th of April 1759, a Youth, John Young, fifteen Years of Age, was admitted into the same Hospital for a Fever, which had already continued fourteen Days. His Speech was affected, and he had entirely lost the Use of his Limbs, was delirious, and had other bad Symptoms. On the 12th, his Hearing became exceedingly dull, and he recovered daily afterwards, and was discharged, cured, the 2d of May, having recovered the Use of his Legs as well as got free of the Fever.
