• An isolated sinus venosus of a shark was divided into two halves still connected to each other by several muscle bundles similar to a bridge. Rhythmic activities of both halves were studied with extra- and intracellular techniques. 1. The electrical activity of one half of the connected sinus venosus was modified by the other half. 2. A small depolarizing potential induced by adjacent fibers could be recognized and was assumed to take a mediating role in maintaining a coordination of the rhythm between the two halves of the sinus venosus. 3. The evidence presented suggests that the rhythm of the sinus venosus is formed as a result of the integration of those of the individual automatic cells.
