Optical activity differentiating the flowing and nionflowing amoebic cytoplasm was detected. This evidence indicates mtiolecular alignment in the flow stream and can be used to provide data on the direction of alignmtient. The results were obtained by utilizing a dynamnic polarized-light detection system which is sensitive only to specimenis which possess a preferred axis.
