Among substances not of organic origin, the most notable instances are hydrated silicic acid, and hydrated alumina, with other metallic peroxides of the aluminous class. This property of colloids enabled Mr. Graham to account for a number of special results of observation, not previously explained.
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.
Rosebuds covered with dew violets in their mossy bed and truck like that. She's lived on Long Island twenty years and never saw New York City before. I ran against her on Thirty-fourth Street. She'd just got in on the East River ferry. I tell you, she's a beauty that would take the hydrogen out of all the peroxides in the world.
More heterogeneous, less stable, and therefore later in the Earth's history, are the deutoxides, tritoxides, peroxides, &c.; in which two, three, four, or more atoms of oxygen are united with one atom of metal or other element.
The peroxides come of that class." Again the photograph did duty. "I could almost wish that she were the lost lady of the cab of the sleeping horse so that I might see her in the flesh. I've never seen her, you know." Harleston smoothed back a smile.
It has a well, you would not call it exactly a crinkle or precisely a wave, but rather somewhere between the two. Yes, I think I should describe it as a ripple. I fancy it must be rather like the reflection of a sunset in a duck-pond, say, with a faint wind ruffling the water. For I gather that her hair is of some light shade, induced, I haven't a doubt, by the liberal use of peroxides.
The experiments which have been made for the purpose of investigating the application of the electric current in quantitative analyses are very few, about the only exception being the separation of copper from the metals which are not precipitated from a nitric acid solution, or which are deposited as peroxides at the other electrode.
More heterogeneous than these, less stable, and therefore later in the Earth's history, are the deutoxides, tritoxides, peroxides, etc.; in which two, three, four, or more atoms of oxygen are united with one atom of metal or other element.
