Excerpt from Preventive Medicine: Two Prize Essays; The General Principles of Preventive Medicine, And, the Medical Inspection of Schools, a Problem in Preventive Medicine
Diseases are characterized by metabolic nerver sions occurring within the body, from the toward action of physical, chemical or organ agents or psychic inﬂuences. The energy of ual factors, while important in the origin, are usually inconspicuous in the manifestations of dis ease. Thus, the force of the percussion cap is not appreciable in the effects of the explosion it incites. The manifestations of disease are not limited by the number of casual factors, but by the number of reactions that may be shown by the tissues. This we should not forget - that disease expresses the reaction of the organism, not the action of the so-called gem.
