5. The persistence of this disease in the deeper parts long after it is outwardly cured, leads to the unsuspected communication of the disease to women with whom the individual may cohabit. Among these women may be his bride, who thereupon enters upon a period of ill-health that may ultimately compel the mutilation of her sexual organs by a surgical operation to save her life. Much of the surgery of these organs performed upon women has been rendered necessary by gonorrhoea, contracted from the husband. Should she while infected with this disease, give birth to a child, the baby's eyes may be attacked by the infection, sometimes with immediate loss of sight. Probably 25 per cent of the blindness of children is thus caused. 6. The other serious venereal disease, syphilis, infects the blood and therewith all parts of the body. For months after infection with this disease, the individual may communicate it by a kiss as well as by cohabitation; and articles moistened by his secretions--towels, drinking glasses, pipes, syringes, etc.--may also convey the infection. While under proper treatment the disease is not dangerous to life in the earlier years, yet the possibilities of transmitting the contagion should forbid marriage for at least three years. The most serious results of syphilis appear years after its acquisition, when the individual has been lulled into a false sense of security by long freedom from its outward manifestations. It attacks all organs of the body, slowly and insidiously producing the symptoms of consumption, dyspepsia, liver disease and many other ailments. Since we have at present no reliable means for proving that one who has acquired the disease is absolutely cured thereof, physicians impress upon these patients two injunctions: first that they shall take the known remedies for the disease one or two months in every year, and second that they shall confide to every physician whom they may consult for any chronic or obscure ailment, the fact that they have been infected with syphilis. This latter injunction is especially important; for nearly all disorders produced by syphilis can be promptly checked by certain remedies; yet many of these disorders affecting internal organs of the body, may not be identified as of syphilitic origin by the unsuspecting physician, who therefore fails to administer the needed and successful remedy. By directing the doctor's attention to the possible syphilitic origin of the disease through a frank confession of his early infection, the patient may save his health or even his life.
