§ 455. Such Ulcers as are of a long Duration, which spread wide, and discharge much, prey upon the Patient, and throw him into a slow Fever, which melts and consumes him. Besides, when an Ulcer is of a long Standing, it is dangerous to dry it up; and indeed this never should be done, but by substituting in the Place of one Discharge that is become almost natural, some other Evacuation, such as Purging from Time to Time.
We may daily see sudden Deaths, or very tormenting Diseases, ensue the sudden drying up such Humours and Drains as have been of a long Continuance: and whenever any Quack (and as many as promise the speedy Cure of such, deserve that Title) assures the Patient of his curing an inveterate Ulcer in a few Days, he demonstrates himself to be a very dangerous and ignorant Intermeddler, who must kill the Patient, if he keeps his Word. Some of these impudent Impostors make use of the most corrosive Applications, and even arsenical ones; notwithstanding the most violent Death is generally the Consequence of them.
§ 456. The utmost that Art can effect, with Regard to Ulcers, which do not arise from any Fault in the Humours, is to change them into Wounds. To this End, the Hardness and Dryness of the Edges of the Ulcer, and indeed of the whole Ulcer, must be diminished, and its Inflammation removed. But sometimes the Hardness is so obstinate, that this cannot be mollified any other Way, than by scarifying the Edges with a Lancet. But when it may be effected by other Means, let a Pledget spread with the Ointment, [Nº. 69], be applied all over the Ulcer; and this Pledget be covered again with a Compress of several Folds, moistened in the Liquid, [Nº. 70], which should be renewed three times daily; though it is sufficient to apply a fresh Pledget only twice.
As I have already affirmed that Ulcers were often the Consequence of sharp and spirituous Dressings, it is evident such should be abstained from, without which Abstinence they will prove incurable.
To forward the Cure, salted Food, Spices, and strong Drink should be avoided; the Quantity of Flesh-meat should be lessened; and the Body be kept open by a Regimen of Pulse, of Vegetables, and by the habitual Use of Whey sweetened with Honey.
If the Ulcers are in the Legs, a very common Situation of them, it is of great Importance, as well as in Wounds of the same Parts, that the Patient should walk about but little; and yet never stand up without walking. This indeed is one of these Cases, in which those, who have some Credit and Influence in the Estimation of the People, should omit nothing to make them thoroughly comprehend the Necessity of confining themselves, some Days, to undisturbed Tranquillity and Rest; and they should also convince them, that this Term of Rest is so far from being lost Time, that it is likely to prove their most profitable Time of Life. Negligence, in this material Point, changes the slightest Wounds into Ulcers, and the most trifling Ulcers into obstinate and incurable ones: insomuch that there is scarcely any Man, who may not observe some Family in his Neighbourhood, reduced to the Hospital, [98] from their having been too inattentive to the due Care of some Complaint of this Sort.
I conclude this Article on Ulcers with repeating, that those which are owing to some internal Cause; or even such as happen from an external one, in Persons of a bad Habit of Body, frequently require a more particular Treatment.
Of Frozen Limbs.
§ 457. It is but too common, in very rigorous Winters, for some Persons to be pierced with so violent a Degree of Cold, that their Hands or Feet, or sometimes both together are frozen at once, just like a Piece of Flesh-meat exposed to the Air.
If a Person thus pierced with the Cold, dispose himself to walk about, which seems so natural and obvious a Means to get warm; and especially, if he attempts to [99] warm the Parts that have been frozen, his Case proves irrecoverable. Intolerable Pains are the Consequence, which Pains are speedily attended with an incurable Gangrene; and there is no Means left to save the Patient's Life, but by cutting off the gangrened Limbs.
