Such a case occurs when large beds of vegetable substances are buried under layers of sediment which subsequently become stone, and thus shut the hydrocarbonaceous compounds beneath them from all access to oxygen.
The substances thus formed by a weak union of carbon with hydrogen are called hydrocarbons.
This gas that is disengaged from the upper part of the fuel consists chiefly of nitrogen and carbonic oxide, mixed with volatile hydrocarburets derived from the fuel used.
Under such uncomfortable circumstances our race will have diminished with the diminishing call on their energies, and by the time that the self-repairing and reproducing machines arise, all but a few of the rare inventors, calculators, and speculators will have become pale, pulpy, and cretinous from fatty or other degeneration, and behold around them a scanty hydrocephalous offspring.
I need not observe that headach is a general attendant of all inflammatory states of the brain, whether in the form of phrenitis, hydrocephalus acutus, or idiopathic fever; though with some exceptions in regard to all of them, as I before showed you.

Of course, I know that an odour of peach-blossom in the air, resulting in death, could only be associated with some vaporous effluvium of cyanogen, or of hydrocyanic ('prussic') acid, or of both; and when I at last managed to examine some of the dust under the microscope, I was not therefore surprised to find, among the general mass of purplish ash, a number of bright-yellow particles, which could only be minute crystals of potassic ferrocyanide.
He had some sealed glass capsules of hydrocyanide of potassium in little brass tubes, sewn up in the lining of a waistcoat, and he took one, and must have died instantly.
If a man knows no Latin, he belongs to the vulgar, even though he be a great virtuoso on the electrical machine and have the base of hydrofluoric acid in his crucible.
Bell was never to have another great inventive success, though his speculations and prototypes anticipated fiber-optic transmission, manned flight, sonar, hydrofoil ships, tetrahedral construction, and Montessori education.
Thus Salisbury has indicated the palmella gemiasma, which is found with us in places perfectly free from malaria, while it is often wanting in malarious marshes in the center of Italy; Balestra, a species of alga which is as yet indeterminate; Bargellini, the palmogloea micrococca; Safford and Bartlett, the hydrogastrum granulatum; and Archer, the chitonoblastus oeruginosus.
What is wanted is to know how the atoms of carbon, hydrogen, oxygen, and nitrogen are linked together, for, strange to say, these differences of groupings, which may be found to exist between these three or four elements, endow the compounds with radically different properties and serve us as a basis of classification.
I have heard a young man say, after hearing a few popular chemical lectures, and seeing a few bottle and squirt experiments: Oh, water--water is only oxygen and hydrogen!--as if he knew all about it.
Mr. Naudin's experiments have shown, for example, that artichoke spirits, which could not be utilized by the old processes, give through hydrogenation an alcohol equal to that derived from Indian corn.--La Nature.

She had probably recognized the derelict Sparhawk and had made a note of her present position, in order to report to the hydrographic office.
As the principal objects of my visit were to ascertain the disposition and resources of the Sulus for trade, and to examine the straits leading into the Sulu seas, in order to facilitate the communication with China, by avoiding on the one hand the eastern route, and on the other the dangers of the Palawan Passage, it may be as well to give the result of the latter inquiry, referring those who may be more particularly interested to the Hydrographical Atlas and Memoir.

59' 30'' E. It was my intention to remain for two or three days at a convenient anchorage to enable us to make short excursions into the interior; but the vexatious mismanagement of the tender now made it incumbent that I should make every possible use of the time to complete the operations connected with the hydrography of this sea; for I perceived that the duties which I intended should be performed by her, would now devolve upon the boats, and necessarily expose both officers and men to the hazard of contracting disease.
This process of normal self-division may take place at all periods of life: it may form an early phase of metamorphosis, as in the Hydroid of our common Aurelia, described in the last article; or it may even take place before the young is formed in the egg.
And he knew as much of astronomy as he did of hydrology, could call the stars by name, and define the shapes of the constellations; and she, who had studied astronomy at the convent, was charmed to find that what she had learned was all true.
To these, heretofore, they did use to sacrifice, by that Greek: hydromanteia, or divination by waters.
The word acan meant wine, or rather, mead, the intoxicating hydromel the natives manufactured.

I can't wait for him any longer, so I'm doing his work myself," answered Miss Dickenson, who was tenderly winding a wet bandage round her Juno's face, one side of which was so much plumper than the other that it looked as if the Queen of Olympus was being hydropathically treated for a severe fit of ague.
In the spring of 1865 she was induced, by the entreaty of friends who had themselves tested his skill, to consult Dr. Schieferdecker, a noted hydropathist, and later to place herself under his care.

The water-shield (Hydropeltis) is chief maid-of-honor; she is a highborn lady, not without royal blood indeed, but with rather a bend sinister; not precisely beautiful, but very fastidious; encased over her whole person with a gelatinous covering, literally a starched duenna.
