Examples

    Alphonse Laveran - Nobel Lecture

  • It is spread from person to person by the bite of the tsetse fly, which carries the protozoon and is famous for that reason.

    The Human Brain

  • Let us begin our comparative study with an example of the simplest animals that consist of only a single cell, such as the little protozoon

    The Doctrine of Evolution Its Basis and Its Scope

    Disease and Its Causes

    Mysticism and Logic and Other Essays

    The Montessori Method

  • All this being known at the time of Laveran, and the malarial parasite being known to be a protozoon, it would have seemed logical to consider its segmentation in the stroma of the red corpuscle as the phase of scission and to await until the parasite gave place to the sexual forms, which must necessarily come in the phase succeeding scission.

    The Montessori Method

  • The living being -- protozoon or vertebrate, notwithstanding its differentiation of material parts and manifoldness of structure, is truly one.

    The Catholic Encyclopedia, Volume 9: Laprade-Mass Liturgy

  • This evolution of matter from the protozoon to man, announced from university chairs as the result of science, was eagerly taken up by the social democrats, and became the fundamental tenet of their conception of the world and of life.
