Chick embryos at 3 to 15 days of incubation were examined for the developmet and differentiation of the “four rings” of the heart. It was clarified that nodes and bundles of the impulse conducting system in the adult chicken were derived from these rings. This finding was very important for understanding the cardiac conducting system in birds and mammals.
