Figs. 9-12 from pieces including the whole naked region of 50-60 mm. animals. Fig. 13 from piece including whole naked region of 70-80 mm. animal. The figures are slightly above natural size. This lateral operation has been performed on thirty-five stem pieces and of these fifteen, or forty-three per cent, have given rise under standard conditions to new lateral axes consisting of at least a hydranth and more or less stem. Twenty pieces, fifty- seven per cent., healed without giving rise to new axes. Among the new lateral axes three, , nine per cent, of the total, became complete by the development of a basal end from the lateral stem region opposite the lateral hydranth. It has been shown in earlier papers (Child, '26^, '270, fr), that either cut end or both, or any other region of a piece may develop as a basal end under inhibiting external conditions. In the light of these results it is to be expected that regions of lateral injury may also be made to develop as basal structures under inhibiting.
