You know that this substance has been used a good deal by modern painters and that it has a very dangerous peculiarity; I mean its tendency to liquefy, without any very obvious reason, long after it has dried." "Yes, I know. Isn't there some story about a picture of Reynolds' in which bitumen had been used? A portrait of a lady, I think.
"Here," says Professor Ramsay, in effect, in a late paper to the society, "is the apparatus with which we liquefy hydrogen in order to separate neon from helium by liquefying the former while the helium still remains gaseous."
There never was enough to drink, but even then there are always men who would rather wash than drink, and to see these men having their bath in a jam-tin just showed how habit is, in many of us, stronger than common sense, for there was never water enough to more than spread out the dirt or liquefy it so that it would fill up the pores.
The passengers saw the moisture in the air turn into snow, and saw the air itself first liquefy and then freeze into a solid coating upon the metal around the orifices at the touch of the frightful cold outside the absolute zero of interstellar space, about four hundred sixty degrees below zero in the every-day scale of temperature.
In its early stages a gumma is a firm, semi-translucent greyish or greyish-red mass of tissue; later it becomes opaque, yellow, and caseous, with a tendency to soften and liquefy.
The result of this first experiment is patent: the Bluebottle's grub is the medium that converts coagulated albumen into a liquid. The value of chemist's pepsin is estimated by the quantity of hard-boiled white of egg which a gram of that agent can liquefy. The mixture has to be exposed in an oven to a temperature of 1400 F. and also to be frequently shaken.
Feeling confident, then, that I could rely upon them, I next turned to my furnace, which I had filled with numerous pigs of copper and other bronze stuff. The pieces were piled according to the laws of art, that is to say, so resting one upon another that the flames could play freely through them, in order that the metal might heat and liquefy the sooner.

It is, however, singular that it should be the spectrum of crypton, that is to say, of the heaviest gas of the group, which appears most clearly in the upper regions of the atmosphere. Among the gases most difficult to liquefy, hydrogen has been the object of particular research and of really quantitative experiments. Its properties in a liquid state are now very clearly known.
They will represent the Faith as creeping like an Oriental disease into the body of a firm Western society which it did not so much transform as liquefy and dissolve. These are contrasted against the diseased Catholic body of the Roman Empire which they are pictured as attacking. Others adopt a simpler manner.
