The caustic humours which an ulcer contains, vitiate the nutritive lymph, and prevent its assimilation to the substance of the corroded fibres; and besides adhering to these fibres, they keep them in a state of rigidity, and oppose their extension. The first reason therefore, showing the necessity of suppuration in order to cure ulcers, is to evacuate these humours. The next is to dissolve the callous edges of the ulcers, and to aid the corroded fibres to discharge the viscid fluids with which they are filled. Thus having used diachilum cum gummis, I employ four times a day injections made with a weak solution[11] of sal ammoniac in common water, and order the injection to be kept in the urethra five minutes every time. Mean while I make use of a weaker suppurative, such as[12] _l’onguent de la Mer_. The time the injection and suppurative are to be continued, is likewise to be proportionate to the inveteracy of the disease, and must be longer if any astringent injection has been made use of, or any callous had been discovered in the urethra by passing the probe up to it. When the use of this suppurative is discontinued, I employ another made with Gold lytharge ℥ vj. Oil of olives ℥ xji. Yellow wax ʒ jv. Venet. turpentine ʒ ji. Bol. Armœn ʒ ji. Every day I render it less suppurative by mixing with it a few drops of Peruvian balsam, and continue its use till the ulcers are consolidated. The space of time necessary to perfect the cure of slight gleets, is generally from twenty-five to thirty days; and of stubborn ones, seldom exceeds ten weeks. But to these observations I must add a few others very material. Sometimes patients who labour under these complaints, are of a habit of body scorbutic, or infected with the venereal taint; in such cases the humours ought to be purified, before the cure of the ulcers is attempted. If the patient is of a phlegmatic or plethoric habit of body, the ulcers are always difficult to heal. A drachm of bark in powder should therefore be prescribed to be taken in a glass of red wine, every day during the treatment. Such is my method of curing gleets; and if ten years practice attended with constant success, may be allowed a sufficient time to convince of its efficacy, I may confidently offer this my idea to the sensible practitioners, and flatter myself that every one who shall adopt it, will find the greatest satisfaction in this respect. Among the great number of instances I could quote to evince its superiority over all other methods hitherto in vogue, I confine myself to the two following.
