ABSTRACT
The determination of the reactions and behaviour of isolated fragments of a protozoan is of value to the study of three problems, namely, the relationship between the nucleus and behaviour, the detection of any area in the organism specialized for the reception of external stimuli, and in the case of a cihate, the role played in normal swimming by the cilia of different regions of the body. Recently, an account has been given of the reactions of fragments of Amoeba proteus (Clark, 1944). The present paper is an extension of the work to include a ciliated form.
