THE TREATMENT OF SYPHILIS. It was at the close of the fifteenth century that syphilis began to spread through Europe. There are doubtful evidences of its existence in both Europe and Asia long previously, but the theory is generally accepted that it was brought from America by the sailors of the earliest expeditions, while its rapid spread throughout the old world in the decade from 1490 to 1500 has often been attributed to the Spanish Jews in the first place, and also particularly to the siege of Naples by the French in 1495. That large numbers of the French soldiers then engaged contracted it in the course of that war is undoubted, and as they were largely instrumental in spreading the contagion the disease soon came to be known as the French disease, or morbus Gallicus, though it has been questioned whether the adjective was not originally a reference to the skin diseases known under the name of “gale” or “itch.” The opinion that syphilis came from the west is not universally adopted. It has been pointed out that Columbus only reached Lisbon on March 6, 1493, on his return from his first voyage of discovery; and there are several more or less authentic allusions to the French disease before that date. The rapidity with which this epidemic seized on all the countries of Europe, and the virulence of its symptoms, alarmed all classes and staggered the medical men of the day. Special hospitals were opened and Parliamentary edicts were promulgated in some of the French and German cities, ordering all persons contaminated to at once leave the neighbourhoods. Mercury was one of the first remedies to suggest itself to practitioners. It had been employed by the Arabs in the form of ointments and fumigations for skin diseases, and quacks and alchemists had long experimented with it in the hope of extracting a panacea from it. Before Paracelsus had begun to administer it, Torrella, physician to the Borgias, had prescribed mercurial lotions made from corrosive sublimate, and Jean de Vigo, of Naples, had compounded his mercurial plaster, and mercurial ointment, and had even given red precipitate in pills.
