  <dc:title>Letter from Walter A. Heiby to Marshall W. Nirenberg</dc:title>
  <dc:description>Heiby developed a theory (similar to homeopathy&apos;s law of infinitesimals) known as the reverse effect, that states that &quot;there is a good probability that a vitamin, mineral, or drug that causes or exacerbates a certain disease at one concentration may reverse its role and molify or cure that same disease at another concentration, and vice versa.&quot;  This is the third letter sent to Nirenberg asking for his comments on the theory, which Heiby promised to include on the jacket for the book.</dc:description>
