Abstract

THE view that the contractile vacuoles of Protozoa in many cases perform an osmoregulatory function has been supported by much evidence1 which need not be repeated here. Recent observations carried out on the freshwater peritrich ciliate Carchesium aselli have demonstrated the remarkably close regulation of body volume which is achieved in spite of wide variation in the osmotic stress imposed by the environment.
