It is a general fact, and one not yet accounted for, that scarcely any fossil remains are ever preserved in stratified rocks in which this oxide of iron abounds; and when we find fossils in the New or Old Red Sandstone in England, it is in the grey, and usually calcareous beds, that they occur.
I am not sure that it was correct, for the effects of nitrous oxide is, perhaps, due to a deprivation of mechanically mixed air.
And so it came to pass that deep plots were laid by all parties alike to rid themselves of this little upstart intruder of a poet who wanted to eat everybody up. Nathan, acting on Florine's advice, gained Finot's support by selling him the sixth share for fifteen thousand francs, and Lousteau consequently lost his commission. The wounds of vanity refuse to heal if oxide of silver gets into them.
The oxygen is taken up by the iron to give oxide of iron, and benzene is obtained, thus: C H OH gives O and C H . But there is another hydrocarbon called naphthalene, C H , and this forms not one, but two phenols.
Yet, how great a difference, in appearance and value, between that precious gem and a thimbleful of coal-dust! Again, what are other gems, such as the ruby, the sapphire, the topaz, the emerald, and others? They are nothing more than crystallized clay or sand, with a trifling quantity of metallic oxide or rust, which gives to each one its peculiar color.
Now I kept some worms in a pot filled with very fine reddish sand, consisting of minute particles of silex coated with the red oxide of iron; and the burrows, which the worms made through this sand, were lined or coated in the usual manner with their castings, formed of the sand mingled with their intestinal secretions and the refuse of the digested leaves; and this sand had almost wholly lost its red colour.
Creek is the name given by Australian colonists to precarious water Courses and tributary streams. "You may remember," said Julius Faber, "Sir Humphry Davy's eloquent description of the effect produced on him by the inhalation of nitrous oxide.
The only other metal, besides gold, we have in abundance in this region, is iron, and that is of excellent quality. In some places it is obtained from what is called the specular iron ore, and also from black oxide. The latter has been well roasted in the operations of nature, and contains a large proportion of the metal. It occurs generally in tears or rounded lumps, and is but slightly magnetic.
But between his departure and this moment the carbonic acid and the oxide of carbon had had time to produce asphyxiation, and certainly he would arrive after her death; or, if he found her still living, some one would discover that the draught of the stove had been turned, and seeing it, he would betray himself as surely as by an avowal.
Stir the liquor twice a day for a fortnight, or the shrub will be spoiled. SICK ROOMS. To purify sick rooms from noxious vapours, exhalations, and all kinds of infected air, put half an ounce of finely pulverized black oxide of manganese into a saucer, and pour upon it nearly an ounce of muriatic acid.
