experiment and its published results. Bull. Am. met. Soc., 64(6):614-615.

The GATE field experiments were conducted in 1974. The number of published papers concerning GATE (in AMS journals) climbed steadily in subsequent years but did not peak until 1980, six years later. The six-year lag was 'surprising and significant,' but aside from the observation that later papers employed more complex data sets, no reasons for the lag are offered.

It is argued that the 'evolution of order in living systems and certain nonliving physical systems obeys a common fundamental principle...the Dar- winian dynamic.' An equation, containing the variables necessary for natural selection processes (heritability, variation of type, competition for

resources), demonstrates this principle for a simple non-biological system and short replicating RNA molecules. The authors show that the fitness of an RNA replicator is a function of intrinsic adaptive capacities and resource availability. The application of the Darwinian dynamic to phage T4 and to higher organisms is discussed. Dept. of Molecular and Med. Microbiol., Univ. of Arizona, Tucson, Ariz. 85721, USA. (msg)

Physicochemical hydrodynamics (PCH) encom- passes 'problems related to the influence of fluid flow on chemical or physical transformations and to the influence of physicochemical factors on fluid flows.' Thus, chemists, engineers, physicists and hydrodynamicists convened to consider interface mechanics and multiphase systems, electrochemistry, turbulence theory and its applications, transport phenomena and chemical reaction systems, the PCH of low Reynolds number flow, and the hydrody- namics of biological systems and polymers.

cause of biological extinctions 65 Myr ago. Nature, Lond., 303(5920):797-800.

Tabulations of the genera present before and after the Cretaceous-Tertiary extinctions have revealed certain patterns; organisms with calcium-containing skeletons were the most susceptible. Among the hypotheses proposed for the C-T extinctions is that they were caused by ionizing radiations. It is proposed here that the pattern of extinction in the fossil record emerged as a consequence of neutron activation of certain elements in organisms and in their environment.
