OF ULCERS OF THE GENITAL ORGANS, AND THEIR CONSEQUENCES. It were unprofitable to enter here upon the History of Venereal Affections, as it is a subject of no practical utility, still involved in uncertainty, and mystified by disputation. It will suffice to describe the different forms of the disease, and state the treatment applicable to each. During the last century, and in the beginning of this, much greater ravages were produced by the disease than at the present time; and though this may be, perhaps, partly owing to a change in the poison itself, it is mainly attributable to the mildness of the measures by which it has been, and is, opposed. Every form of the affection, as soon as it appeared, was at one time opposed by a counter poison, mercury; and the practitioner, relying implicitly on this mineral as a specific, and not being fully aware of its dangerous properties, continued to gorge the system with the supposed remedy, subverting the constitution of his patient, making, in many cases, no impression on the disease, but still persevering in the use of a poison equal, if not more potent, than the one which it was intended to destroy. The change of treatment has been propitious to our science and to mankind. But let it not be inferred that mercury now is, or ought to be, entirely dismissed from the treatment of this disease, or from practice generally: often no other means are effectual; but it should always be prescribed most cautiously and sparingly. The effects of the venereal virus are divided into primary or local, and secondary or constitutional; and these present a great variety in their appearances, characters, and tendencies. They are sometimes modified by the constitution, or by the remedies ordered in the first stage; but there can be no doubt that different poisons exist, producing distinct kinds of ulcers, which again are succeeded by different constitutional affections.
