Patients, who were reduced very low by this Fever, or by repeated Relapses, were subject to oedematous Swellings; especially of the Feet, towards the Evening, after sitting up all the Day. These Swellings generally went away as the Sick recovered their Strength; but in some Cases they continued obstinate, and ascended towards the Thighs; and in some spread all over the Body, and terminated in an universal Anasarca. When these Swellings were recent, and confined to the Feet and Legs, commonly the Bark joined to the lixivial Salts, or the Oxymel of Squills, or other Diuretics, and a Purgative once or twice a Week, removed them. In some, an Infusion of Horse-radish had a good Effect; in others, Sweats brought out by means of _Dover_’s Powder, or of the _guttæ antimoniales anodynæ_. Sometimes these Swellings were very obstinate, and resisted the Force of all internal Remedies. In such Cases, Punctures made in the Feet, or lower Part of the Legs, which furnished a Drain for the Water, had a good Effect. Blisters applied to the Legs were of Service to some. When the Punctures were made, or the Blisters applied, before the Patient’s Strength was exhausted, provided that he laboured under no other Disorder but these oedematous Swellings, which proceeded from Weakness, I never observed any bad Effects from them; tho’ I used them both repeatedly in a Variety of Cases. But if the Patient was very weak; or had a Hectic Fever or Purging; or other Disorders, and the oedematous Swellings large; then oftentimes the great Discharge exhausted his Strength, and a Gangrene and Death were the Consequence. One of the most remarkable Instances of the good Effects of Blisters, was in the Case of a Soldier at _Paderborn_; _Thomas Hope_, of the Second Regiment of Foot Guards, after a Fever of this Kind, was swelled all over, especially about the Face and Neck, and had a Difficulty of Breathing: after having tried Variety of Medicines for this Complaint, without any Effect, he had a large Blister applied to his Back, and took the Cortex in a Mixture, with the Oxymel of Squills. As soon as the Blister began to discharge, the Swellings decreased; and were afterwards entirely removed by the Help of one or two Doses of Physic, and the continued Use of the Medicines before prescribed. Three other Men in the Hospital at _Osnabruck_, in _May_ 1761, having oedematous Swellings of the Feet and Legs, which yielded to no internal Remedies, had Blisters applied to their Legs, used the Cortex, with the lixivial Salts, two or three Times a Day, and a Purge every fourth Day; which removed the Swellings in a short Time.
