=Treatment.=--The treatment should be begun as soon as the diagnosis is made, and must be continuously and conscientiously pursued for three years or longer. If treatment is instituted before the secondary symptoms, it may prevent their appearance so that the patient may remain in doubt whether he had the disease or not, for it is impossible for the most skilled specialist absolutely to distinguish the disease before the eruption, no matter how probable its existence may seem. This happens because there are several kinds of sores which attack the sexual organs and which may closely simulate syphilis. The treatment is chiefly carried out with various forms of mercury and iodides, but so much knowledge and experience are required in adapting these to the individual needs and peculiarities of the patient that it is impossible to describe their use. Patients should not marry until four or five years have elapsed since the appearance of syphilis in their persons, and at least twelve months after all manifestations of the disease have ceased. If these conditions have been complied with, there is little danger of communicating the disease to their wives or transmitting it to their offspring. They must moreover, have been under the treatment during all this period. Abstinence from alcohol, tobacco, dissipation, and especial care of the teeth are necessary during treatment. =Results.=--The majority of syphilitics recover wholly under treatment and neither have a return of the disease nor communicate it to their wives or children. It is, however, possible for a man, who has apparently wholly recovered for five or six years or more, to impart the disease. Without proper treatment or without treatment for the proper time, recurrence of the disease is frequent with the occurrence of the destructive and often serious symptoms characteristic of the third stage of the disease. While syphilis is not so fatal to life as tuberculosis, it is capable of causing more suffering and unhappiness, and is directly transmitted from father to child, which is not the case with consumption. Syphilis is also wholly preventable, which is not true of tuberculosis at present. It is not probable that syphilis is ever transmitted to the third generation directly, but deformities, general debility, small and poor teeth, thin, scanty growth of hair, nervous disorders, and a general miserable physique are seen in children whose parents were the victims of inherited syphilis. In married life syphilis may be communicated to the wife directly from the primary sore on the penis of the husband during sexual intercourse, but contamination of the wife more often happens from the later manifestations of the disease in the husband, as from secretion from open sores on the body or from the mouth, when the moist patches exist there.
