When the venereal disease has been neglected, or improperly treated, it often becomes a disorder of the habit. In this case the cure must be attempted by restoratives, as milk diet, the decoction of sarsaparilla, and such like, to which mercury may be added. It is a common practice in North Britain to send such patients to drink goat-whey. This is a very proper plan, providing the infection has been totally eradicated beforehand; but when that is not the case, and the patient trusts to the whey for finishing his cure, he will be often disappointed. I have frequently known the disease return with all its virulence after a course of goat-whey, even when that course had been thought quite sufficient for completing the cure. One of the most unfortunate circumstances attending patients in this disease, is the necessity they are often laid under of hurrying the cure. This induces them to take medicine too fast, and to leave it off too soon. A few grains more of medicine, or a few days longer confinement, would often be sufficient to perform the cure; whereas, by neglect of these, a small degree of virulence is still left in the system, which gradually vitiates, and at length contaminates the whole mass. To avoid this, we would advise, that the patient should never leave off taking medicine immediately upon the disappearing of the symptoms, but continue it for some time after, gradually lessening the quantity, till there is reason to believe the disease is entirely eradicated. It is not only difficult, but absolutely impossible, to ascertain the exact degree of virulence that may attend the disease; for which reason it will always be a much safer rule to continue the use of medicine too long, than to leave it off too soon. This seems to be the leading maxim of a modern practitioner of some note for the venereal disease, who always orders his patients to perform a quarantine of forty days, during which time he takes forty bottles of, I suppose, a strong decoction of sarsaparilla, or some other antivenereal simple. Whoever takes this method, and adds a sufficient quantity of corrosive sublimate, or some other active preparation of mercury to the decoction, will seldom fail to cure a confirmed lues.
