Note 17 — THE INDIVIDUAL ORGANISM WITH REGARD TO FORM AND METABOLISM

In the pressure experiments I had altered the relative position of the nuclei in origine. In later years I succeeded in disturbing the arrangement of the fully formed cells of the eight-cell stage, and in getting normal larvæ in spite of that in many cases. But as this series of experiments is not free from certain complications—which in part will be understood later on (see page 73)—it must suffice here to have mentioned them. (For further information see my paper in Archiv. f. Entwickelungsmechanik, xiv., 1902, page 500.)
