“That which makes the healthiest house makes likewise the healthiest hospital; the same fastidious and universal cleanliness, the same never-ceasing vigilance against the thousand forms in which dirt may disguise itself, in air, in soil and water, in walls and floors and ceilings, in dress and bedding and furniture, in pots and pans and pails, in sinks and drains and dust-bins; it is but the same principle of management, but with immeasureably greater vigilance and skill; for the establishment which has to be kept in such exquisite perfection of cleanliness is an establishment which never rests from fouling itself; nor are there any products of its foulness, not even the least odorous of such products, which ought not to be regarded as poisons. Above all this applies to the fouling of the air within hospital wards by exhalations from the persons of the sick. In such exhalations are embodied the most terrible powers of disease, the spreading flames, as it were, of some infections and the explosive fuel of others; and any air in which they are allowed to accumulate soon becomes a very atmosphere of death.” The subject of hospital sanitation is so large, so many-sided, that to do it justice in the space allotted is impossible. It involves a consideration of the site of the hospital and the plans, the separation of the departments, the materials used in its construction, its ventilating system, its plumbing and sewerage connection, its food and water supplies, its facilities for isolation of infectious diseases, for disinfection, for disposal of the waste and refuse from the various departments, and its arrangement for living conditions for those on whom the responsibility of carrying on the work of the hospital involves.
