1. The activity of dehydrogenase and oxic ase of the auriculo-ventricular functional system was quantitatively estimated and compared with that of heart muscle, with the conclusion that the former is far inferior to the latter in the activity of both ferments.
2. It was found also that the content of sulfhydrvl compounds of the auriculoventricular junetional system is less than that of the heart muscle.
3. It was proved moreover that Tawara's bundle consumes far less oxygen than the heart muscle.
4. From these expp erimental results it is reasonably concluded that the metabolic activity of the auriculoventricular junctional system is much inferior to that of heart muscle.
The author is deeply indebted to Prof. Keizo Kodama and Prof. Makoto Isihara for kind advice throughout this investiga-tion.
