They form part of the very rapid post-war growth in pure and applied sciences of every kind. During this period several branches of biology including immunology, molecular biology and, of course, cryobiology, have split off from their parent disciplines. One result of this splintering has been the development of separate jargons used by the specialists and sometimes incomprehensible to those working in closely allied fields. The pure physicists, chemists, and the applied...
