Samuel Natelson's lecture focuses on his time at the Rockford Memorial Hospital (Rockford, Illinois) as a clinical chemist, where he worked on improving the odds for survival of the premature infants. Specifically, Natelson developed new ways to prevent both dehydration and acidosis. In this lecture he also describes how his work with infants at Rockford was rejected by pediatricians at the time. Natelson is introduced by Amadeo J. Pesce.

The tape cuts at the end of Natelson's talk and resumes during his later remarks at a dinner. At the dinner lecture, Natelson continues talking about his time at Rockford Memorial Hospital and his treatment of premature infants. He reads from several strong, negative reactions to his work, all of which try to discredit his findings.
