Points from Foregoing Letters

    Abstract

    PROF. H. MUNBO Fox shows that the rates of cleavage of sea urchin eggs are adapted to the temperature of the seas in which they live. For a given rate of cleavage, a higher temperature is necessary in a certain Mediterranean species than in an English species of the same genus; and the same phenomenon occurs within another single species in different latitudes.
