Excerpt: ... endoderm, also according to the pre-organized constitution of the protoplasmic materials of the ovum." 23 How is this organization of the squid before cell multiplication begins to be explained in accordance with the conception that the creature's cells are more fundamental than the creature itself and are the cause of the creature? Watase's radical elementalism made it almost obligatory upon him to try to answer the above question. Something of the difficulty which the protozoan colony theory of the higher organism has to face in such cases as this, he seems to have felt, and his way of meeting it certainly has the merit of being ingenious. "Even if we admit," he says, "that the unicellular ovum irrespective of its stages of growth, represents actually the condition of the ancestral protozoan, a highly differentiated axial symmetry of a certain metazoan ovum cannot be said to be an aberrant feature unrepresented in the ancestral protozoa, so long as the existing forms of the protozoa often show such a high degree of differentiation in that particular respect." 23 As though the high degree of axial differentiation in some protozoan imagined to be the faraway ancestor of a squid were an explanation of the axial differentiation of a squid in its unicellular stage! It is hardly possible for speculation to soar on less restrained wings than this and maintain its claim to being scientific. So much by way of illustration of animal groups in which the promorphology consists in a considerable measure of observable differentiation while the individual animal is yet in the one-celled state, or, in other words, of animals in which the individual development has gone some distance in the egg before cell multiplication begins.
