Abstract
IN the present-day economy of Nature the various associations of living creatures work into one another's hands, so that a moving equilibrium results. One of the main ideas of Prof. Meunier's “Biological Geology ” is that analogous associations have existed in the past in similar correlations, the same biocosmic rôle being discharged by successive types. After illustrating the geological activity of organisms in forming and weathering deposits, and in the ceaseless circulation of matter, the author takes an interesting survey of the various haunts of life and their interrelations, and brings forward evidence to show that in past ages there was a somewhat similar biocosmic pattern, with hydroplankton, hydronekton, hydrobenthon, aerial animals, terrestrial animals, even commensals, symbionts, and parasites.
