I pass now to a case of a different character, which has only, within recent years, begun to attract the attention of the moralist and politician at all--the peril to life and health ensuing on the neglect of sanitary precautions. A man carelessly neglects his drains, or allows a mass of filth to accumulate in his yard, or uses well-water without testing its qualities or ascertaining its surroundings. After a time a fever breaks out in his household, and, perhaps, communicates itself to his neighbours, the result being several deaths and much sickness and suffering. These deaths and this suffering are the direct result of his negligence, and, though it would, doubtless, be hard and unjust to call him a murderer, he is this in effect. Of course, if, notwithstanding warning or reflexion, he persists in his negligence, with a full consciousness of the results which may possibly ensue from it, he incurs a grave moral responsibility, and it is difficult to conceive a case more fit for censure, or even punishment. Nor are the members of a corporation or a board, in the administration of an area of which they have undertaken the charge, less guilty, under these circumstances, than is a private individual in the management of his own premises. If men were properly instructed in the results of their actions or pretermissions, in matters of this nature, and made fully conscious of the responsibility which those results entail upon them, there would soon be a marked decrease in physical suffering, disease, and premature deaths. The average duration of life, in civilized countries, has probably already been lengthened by the increased knowledge and the increased sense of responsibility which have even now been attained.
