In relation to the puerperal psychoses, it appears that the first menstruation after the birth of the child has, like the very first appearance of the menstrual flow during the menarche, a tendency to favor the onset of mental disorder. According to _Marcé_, this first post-puerperal menstruation has a very definite significance in the causation of psychoses. Among forty-four cases of puerperal psychoses, there were eleven instances in which the mental disorder made its appearance six weeks after childbirth, exactly at the moment, that is to say, in which, had the mothers not given suck to their children, menstruation ought to have reappeared. In those who did not nurse their infants, and in whom menstruation recommenced at the due date, the psychosis usually began on the first day of menstruation, less often on the fourth or fifth day. In some instances the psychosis appeared at the time at which menstruation might have been expected to occur, but when the flow was still in abeyance. And in some women who suckled their children for a time and then weaned them, the psychosis made its appearance at the time of the first recurrence of menstruation. Among diseases of the sense-organs occurring during the menacme, ocular lesions are by no means rare as sequels of pathological changes in the genital organs. Thus, in cases of displacements of the uterus, especially prolapse, retroflexion, and retroversion, we sometimes see retinal hyperæsthesia and reflex amblyopia, photophobia and lachrymation, and accommodative or muscular asthenopia. Inflammation of the pelvic connective tissue, perimetritic and parametritic exudations, and especially parametritis atrophicans, may give rise to functional disorders of the eye, reflex hyperæmia of the trigeminal and optic nerves, various painful sensations, and photophobia. Severe metrorrhagia may also cause disturbances of vision, either by inducing local anæmia and consequent functional failure of the nervous apparatus, or by leading to serious infiltration of the optic nerve which manifests itself also in the retina in the form of a transudation. In cases alike of congenital and of acquired atrophy of the uterus, and frequently, therefore, in sterile women, optic nerve atrophy may occur. COMPETENCE FOR MARRIAGE OF WOMEN SUFFERING FROM DISEASE. In this section we must consider the competence for marriage of women suffering from heart disease, of those suffering from hereditary tendency to mental disorders and neurasthenic states, and, finally, of those affected with tuberculosis.
