To the younger members of the profession I wish to offer some farther hints on the direct practical bearing of the foregoing truths. The facts of our human organization should not only guide the medical advice given in the consultation-room, but caution us respecting the methods to be adopted in dealing with the poor, and suggest the direction in which national sanitary measures should proceed. The immense power of this passion of sex in the human race must never be ignored in relation to either men or women. The beneficent control which the human mind can exercise over the passion points out that item in the human _materia medica_, which more than any other the physician must strive to secure for the benefit of his patient, viz.--force of will. He is bound to declare the sovereign efficacy of this natural specific, and enforce the methods of securing it. All physical and hygienic means must be called upon to develop and support that power of will and that mental purity which alone can govern wisely the human sexual nature. There is another point which cannot be too strongly insisted on. The personal modesty of patients--that elementary virtue in Christian civilization--must be carefully cherished by the physician, who, more than any other, is acquainted with its influence on the sexual nature. The common resort to sexual examination is an evil grown up in medical practice of comparatively modern date. The use of the speculum should be strictly limited by absolute necessity. Its reckless use amongst the poor is a serious national injury. I know from fifty years’ medical experience amongst the poor, as well as the rich, that this custom is a real and growing evil. It should be a last resort of medical necessity, and it is so regarded by thoughtful physicians. That it is sometimes necessary is unhappily true; and when a poor sufferer learns from her trusted adviser that such investigation is quite unavoidable, acceptance of such judgment is the part of wisdom and true modesty. But it is essential that the medical judgment thus rendered should be final--the result of age and special experience. The wise custom of many physicians to decline practice in which a very special training has not given them the positive knowledge of an expert should be a universal rule. It is a social wrong when the serious character of this branch of medicine is not conscientiously acknowledged. The natural sentiment of personal modesty is seriously injured amongst respectable people by the resort to a succession of incompetent advisers.
