Abstract

THE restriction of increase of size to the immediate post-ecdysal period is a feature of growth peculiar to Arthropods. The rapidity of the increment suggests that it is due merely to inflation of the body with fluid1,2,3, while true growth, that is, the addition of new protoplasm and cell division, is probably continuous as in other groups. There remains the question : Does the post-ecdysal inflation affect the cavities of the body, the tissues, or both?
