        [May one] doubt whether, in cheese and timber, worms are generated,
        or, if beetles and wasps, in cow-dung, or if butterflies, locusts,
        shellfish, snails, eels, and such life be procreated of putrefied
        matter, which is to receive the form of that creature to which it
        is by formative power disposed[?]  To question this is to question
        reason, sense, and experience.  If he doubts this, let him go to
        Egypt, and there he will find the fields swarming with mice begot
        of the mud of the Nylus, to the great calamity of the inhabitants.
                A seventeenth century opinion quoted by L. L. Woodruff,
                in *The Evolution of Earth and Man*, 1929
