[18] But although these parotid Swellings were in general so favourable with us, we are not to imagine that this will always be the Case: for _Riverius_, though he speaks of these Swellings proving for the most part critical; yet he tells us, that, in the Year 1623, this Fever was epidemic at _Montpelier_, and that almost one half of the Sick died; and particularly, that most of those who had Swellings of the parotid Glands appearing about the 9th or 11th Day, were carried off within two Days of their Appearance. Having attended several who died from the Swellings not coming to Suppuration, he began to consider in his own Mind, what might be the Cause of their Death, and concluded, that it was owing to there being a greater Quantity of morbid Matter in the Blood than the Part was able to contain, and that Evacuations by blooding and purging were the only Remedies which were likely to give Relief; and therefore, in the first Case of this Kind, in which he was afterwards consulted, he ordered three Ounces of Blood to be taken away, notwithstanding the Patient was so low that the Surgeon was afraid he would have died in the Operation: The Pulse rose on bleeding, and he ordered four Ounces more to be taken in three or four Hours afterwards: The Pulse rose still more, and he ordered a Dose of Sena and Rhubarb to be taken next Day, and the Patient recovered. And he adds, that all those who were treated in this manner got well. _Prax. Med. Lib._ XVII. _sect._ iii. _cap._ 1. As soon as these Swellings of the parotid Glands appeared, we endeavoured to bring them forward to Suppuration, by the Application of emollient Cataplasms, or of gummous Plaisters; and had them opened as soon as a Fluctuation of Matter was to be felt, and afterwards treated them as common Abscesses. _Riverius_[19] very justly observes, that when such Tumours encrease in such a Manner as to endanger Suffocation, they ought to be opened before they come to Maturation; and Dr. _Pringle_[20] desires us not to wait for a Fluctuation of Matter, but to open the Abscess as soon as it can be supposed to have formed.
