Note that there is practi- cally no acid phosphatase except in the nuclei, although there is an occasional granule here and there. Compare the sparseness of acid phosphatase in the young ani- mal with Figure 8 which shows a ten-day-old hydranth in early stages of regression. Particularly notice the enormous numbers of very small acid phosphatase-positive granules, which are nearly everywhere in the gastrodermal cells. Notice th
