THE UNSOLVED PROBLEMS OF PREVENTIVE MEDICINE.
An inventory of the present status of the disease entities with which the modern sanitarian and clinician have to deal tempers the facile optimism of the unthinking. Whereas the infections transmitted by insects, the waterborn diseases, and certain diseases for which we possess methods of specific immunization have been well conquered, we are still unable to control the high mortality from degenerative diseases of the heart, bloodvessels and kidneys, from pneumonia and other acute respiratory infections, cancer and, to a less extent, tuberculosis. To map out the varied lines of attack upon these unsolved problems is the object of this paper.
