Part of Charles Urban’s Unseen World programme (1903), this microcinematographic short begins with a frog swimming in a tank, then focuses on its webbed foot. The final section reveals a magnified view—about 500×—of blood coursing through the tiny veins, offering Edwardian audiences a vivid first glimpse of living circulation in motion.
