The "cure" is based upon the establishment in the patient of right nutrition, right functioning of the bodily organs and secretions, and thereby assisting Nature to perform the cure in a natural manner. Pure foods and other conditions of right nutrition have been the particular study of the institution staff, and large and finely furnished chemical and bacteriological laboratories have been installed for the study of nutrition in a scientific manner. The Battle Creek Sanitarium is a purely humanitarian and philanthropic institution. By perpetual charter, all of the profits of the concern in all of its ramifications are dedicated to the extension of the American Medical Missionary Cause, and there have been already established more than sixty branches of the parent institution in different parts of the world, principally in or near the chief cities of America, and all are occupied with saving and regenerating the physical body of the sick as a foundation for possible moral awakening and spiritual cultivation. The work done by these humanitarian institutions is most practical, and the best evidence of the practicality is their growth. Patients are charged what they can conveniently pay, but none who need are refused attention. Branches are made self-supporting as soon as possible, but are first nurtured by the parent sanitarium. There are some hundreds of physicians, nurses, and other attachés of the different institutions, and these are enthusiasts in the humanitarian work, taking as wages only what they need for most economical support, "a mere pittance," and deriving their chief compensation from satisfaction gained in the service. All in all, it is an expression of inspirational altruism worthy of the example of the Good Samaritan and a practical demonstration of the Sermon on the Mount.
