It is well known, that practitioners employ but one kind of suppurating bougies, made with a plaister, whose basis is lytargirium of lead and oil of olives; whilst, in order to conduct suppuration properly, bougies should be more or less suppurative, according to the stages of the disease. Having for a long while made use of suppurative bougies, practitioners use dessicative ones, even when suppuration is still abundant. But to those who have the least notion of the means employed by nature in the reproduction of fleshy substance, it is evident, that such a sudden passage from active suppurative remedies to dessicative ones, never can produce the desired effect. After a forced suppuration, kept so for a long while, far from being incarnated, the cavity of the ulcers is widened, and all the fibres around it have lost their natural elasticity. Thus dissicative bougies employed immediately afterwards, being all of an astringent quality, and acting on the part alone they are in contact with, can only dry and crisp the edges of the ulcers, and cause them to become callous. The running is therefore stopt for a time, and never fails to break out again, when circulation is considerably increased by any accidental cause. The use of common bougies, as they are actually made, is not only defective, but unrational and hurtful. In common bougies, the suppurative plaister is spread over their whole superficies. Now, to apply the remedy in every point of the urethra, in order to cure some ulcerated parts, is certainly very absurd. What is commonly alledged in support of such a practice is, that it is only by giving to the medicament this extension, that it can be sure of reaching and acting on the diseased parts; but the seat of the distemper can easily be found, by gently introducing a probe into the urethra, and there only may the remedy be applied.
