HUMAN PROGRESS has always come in waves, and for the last quarter of a century we have been on the crest of a wave of scientific advancement which gives no sign of ebbing. Some of mankind's most stubborn killers and cripplers are being conquered by new medical discoveries. But no matter how dramatic, no discovery, no miracle of medicine can stand alone. Witness the Salk vaccine. We have in our hands the means of controlling poliomyelitis, but ve are not making the most of it. Only abouit one in four people in the United States has been immunized against this (lisease. Another facet of the same problem is bIow to make available dramatic discoveries such as those in heart surgery. New hope for life is exciting to us, and even more so to the parents of children with heart defects. But the cost of diagnosis, surgery, and aftercare is absolutely prohibitive for many parents who could take in stride a simple operation or illness. The very fact that new knowledge and skills exist has created a new category of medical indigency. Some old concepts need reexamination when we face the alternatives of possible cure for some $3,000 against certain invalidism costing untold thousands or even death. Under such circumstances what is sound economy? We have learned that after a medical discovery comes the need for a network of services to spread the benefits of that discovery. When economic barriers obstruct securing these services, we must find out how they can be overcome. We
