But I will heat the ether so as to convert it into a gas.
Albano and Schoppe climbed together those pure heights of the mountains of the Muses, where, as on natural ones, the atmosphere of life rests lighter, and the ether draws nearer to the shortening column of air.
The tones hovered and hung twining together into one wreath, high in their ether above the noisy swarm of men, and sang down to them their heavenly songs.

The truth is, I had taken ether in the evening for a touch of neuralgia, and it set my imagination at work in a way quite unusual with me.
A sharp pain coming on, ether was administered with relief.
Newton's hypothesis of anether filling the heavenly spaces does not, I confess, help my conceptions.
I don't believe the human gamut will be cheated of a single note after men have done breathing this fatal atmospheric mixture and die into the ether of immortality!
The atmosphere of memory is one in which imagination flies more easily and feels itself more at home than in the thinner ether of youthful anticipation.
It is because the molecules of this spiritual ether are nothing but the souls of the living, the dead, and the unborn, and any vibration of the spiritual ether must inevitably cause a certain vibration of its atoms.
The ether rises to the top, carrying with it the bromine in solution; after being withdrawn, this ether is mixed with potassa, by which the bromide and bromate of potassa are formed.
Bromine may be readily detected by passing a current of chlorine through the fluid, after which ether is added and the whole is agitated.
Since brick does not elastically vibrate to such infinitesimal impulses as electric waves, ether must.
The existence of an all-pervasive medium called the luminiferous ether was launched as a theory.
Sir William Thompson thinks he has proved that a cubic mile of celestial ether may have as little as one billionth of a pound of ponderable matter.
This incredibly high-class energy is not banking up coal in the celestial ether as it did on the earth, but is returning to the quick, mobile forces of the invisible worlds.
Ether is so rare that its density, compared with water, is represented by a decimal fraction with twenty-seven ciphers before it.
Marvelous discoveries in the capacities of ether have been made lately.
Ether is a far better medium of transmission than iron.
Between two hundred and four hundred millions of millions of vibrations of ether per second are the different sorts of heat.
If ether can so readily go through such solids, no wonder that a spirit body could appear to the disciples, "the doors being shut.
Since some kinds of electricity do not readily pass through space devoid of air, though light and heat do, it seems likely that some of the lower intensities and slower vibrations of electricity are not in ether but in air.
That is to be expected from the generally-accepted idea that the apparent velocity of any ether vibration is independent of the velocity of either source or receiver.
The fourth order rays, of which the theory has been completely worked out, are the shortest vibrations that can be propagated through the ether; for the ether itself is not a continuous medium.
That barrier in the ether seems impervious, and if so, it could not transmit a blow.
Crystallized ether would displace fluid ether, so it might--I'll give up!
The zone of force is necessary to shield certain items of equipment from ether vibrations; as any such vibration inside the controlling fields of force renders observation or control of the higher orders of rays impossible.
Nothing in theether spectrum is corkscrewy enough to get through it.
Its solution in alcohol or in ether is known as tincture of iodine.
Ethyl alcohol and methyl ether have the same number of the same elements, C2H6O, but their molecular structure is not the same, and hence their properties differ.
