These experiments were done in accordance1 with an objective somewhat different from the one included in this report. The details of these experiments will hi1 reported later. However, as the pieces of the animal were passing through the phases of regeneration several results were pertinent to the problem considered herein. The oral pieces usually regenerated the lost portions of the body per- fectly in all details. Hv this regeneration the regular connections of canals and rows were soon established and the single, apical organ was.
