1. Wenn das Tier nach 20-stündigem Fasten getötet wird, so zeigt der Glykogengehalt der Leber bei kohlenhydratreich wiearm genährten Hunden einen fast gleichen Wert, namlich bei jenen 0.42-0.72 Proz. und bei diesen 0.46-0.67 Proz.
2. Bei Durchblutungsversuchen wurde der Glykogenansatz der Leber bei kohlenhydratreich genährten Hunden sehr auffallend (97-192 Proz.), aber bei den mit Eiweiss-Fettdiät gefütterten nur unbedeutend (17-67 Proz.) gefunden.
3. Diese Herabsetzung der Glykogenbildung in der Leber soll für die Beeinträchtigung der Zuckerassimilation durch Eiweiss-Fettdiät sicher ein ätiologisches Moment darstellen.

1. A new micro-gasometric apparatus is devised.
2. A monng the chloride of several heavy metals the catalytic activity of iron is most effective, while copper comes next, and salts of other metals remain very weak in their effectiveness.
3. This catalytic activity seems to be due to the presence of metallic ion.
4. The catalytic activity of iron chloride weakens therefore proportionately with the increase of hydrolysis.
5. The oxidative activity of salt of iron and other metals is almost parallel with their catalytic activity.
6. The presence of caolin, at a certain amount, promotes both the catalytic and oxidative activity of iron salt. The excess of caolin, however, retards the activity of iron. The repeated treatment of caolin with iron chloride lessens the effectiveness of caolin in promoting the activity of iron salt probably oaring to the deformation of the surface.
7. The addition of a certain amount of isoclectric albumin to the system of H₂O₂+FeCl₃ accelerates the catalytic action of iron salt on hydrogen peroxide, while the optimum concentration, at the other acidity than the isoclectric point, shifts to either direction.
8. The same relation as that of albumin is also observable in case of the addition of lecithin and cephalin.
9. The presence of iron salt retards the action of hemase very clearly.
10. The presence of hemase acts favourably on the catalytic activity of iron salt at a certain concentration just as in the, case of albumin. This effectiveness of hemase is found to be Clue to its albumin content.
11. The presence of peroxiclase retards the activity of hemase.
12. The presence of heiuase promotes the activity of peroxidase and oxidase when the amount of hydrogen peroxide present is large, while in the case where the amount of hydrogen peroxide is not sufficiently large for the action of peroxidase, it acts retardingly.
