Excerpt from The Unity of the Organism, Vol. 2: Or the Organismal Conception of Life
In our discussion we will be guided by the principle laid down earlier and followed throughout our treatment of heredity in the Protozoa, namely, that descriptive ontogenesis brought to bear on the actual transformations which result in the production of specific organs and parts, is the final tribunal for the determination of what substances are hereditary formative. The first inquiry will be whether there exist among the metazoa single-cell organs or parts which when fully formed exhibit species characters in the sense of taxonomic biology. If such elements do exist, observation on the constituents of the undifferentiated cells which take part in the transformations, obviously may be expected to give us the information sought as to what substances are formative.
