Abstract
REPETITIVE or strobed electronic flash has been commonly used in techniques for the analysis of animal locomotion. Some of the methods involved several flashes on to a single photograph, notably in connexion with work on the flight of birds and bats. Dryl1,2 has described a ‘photomacrographic’ method for recording the activity of mobile protozoans. This utilized a time exposure to a continuous source of light illuminating the animals against a dark background. His method was developed from similar ‘photomicrographic’ techniques for activity recording used by other workers3–6.
