[17] _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. Swellings of the parotid Glands appeared in many Subjects, towards the Decline of the Fever, which came to Suppuration, and proved critical. In two only, out of those I attended while in _Germany_, they came on early in the Fever, but did not suppurate. Both Patients died; all the rest recovered, except one old Man, an Invalid at _Bremen_; who, after having one Swelling appear on the right Side, which came to Suppuration, and seemed critical, relapsed into the Fever; and another formed on the other Side, which came likewise to Suppuration, and the Fever ceased, after having reduced him very low; but the great Discharge from the Sores wasted him gradually, and he died hectic in about a Month after the Fever had left him[18].
