Name some of the Oxides of iron.

Now it has been observed, that if this decomposition of the peroxide of hydrogen takes place in contact with some metallic Oxides, as those of silver, and the perOxides of lead and manganese, it superinduces a corresponding chemical action upon those substances; they also give forth the whole or a portion of their oxygen, and are reduced to the metal or to the protoxide; although they do not undergo this change spontaneously, and there is no chemical affinity at work to make them do so.

Dr. Liebig recognised, in the known chemical properties of the Oxides of iron, laws which, if followed out deductively, would lead to the prediction of the precise series of phenomena which respiration exhibits.
