Abstract

Now that the enthusiasm for finding an organism as the causal agent in malignant tumors has somewhat diminished, it will be noted with interest that the direction the investigation of new growths is taking is along chemical lines. This is fully in accord with the general trend of modern biology and medicine. Undoubtedly, the chemical side has been too much neglected, though the progress of investigation of the problem from this point of view is entirely dependent on the progress of general physiologic chemistry, and this we know is comparatively a new field. In recent years attention has been called in many ways to the importance of the inorganic constituents of the organism in promoting vital activities. Though these elements are all present in small quantities and some in even the minutest quantities, still their action appears to be specific and their presence indispensable to the organism. The presence of
