The ' days ' of Genesis were twenty-four hours long. Hurrah ! " The life of geology was scarcely conscious of a ripple. The old principles rest firmly. The facts cited, instead of proving destructive, confirm another doctrine even more dreadful than that of successive faunas and great antiquity — the doctrine Lesson prom i. Lump of Chalk. 169 of correlation of organic structure with environment. Faunas change as the physical surroundings change ; but if the physi- cal surroundings remain change...less, the faunas remain change- less. Down in the deep sea, with a constant temperature of freezing water ; with perpetual absence of the stimulus of light ; without inotion ; without change of chemical condi- tions — with almost absolute changelessness for ages, why should organisms change ? They are now suited to the environment ; they could not change without becoming unsuited to the en- vironment. The forms from the Age of Chalk have survived because a deeper principle than that of succession of faunas has been dominant.
