It was solid at 9° C., and sufficiently soft to flow at 12° C., but did not entirely liquefy under 22° C. To test its neutralizing power, 0.9575 gramme dissolved in alcohol was titrated with decinormal alkali; it required 34.05 c.c.
In the solid form the molecules are so packed together that, of course, the motion is excessively restricted; in the liquid it is a little easier; in the gaseous state the molecules are in a comparatively "open order." In most substances that are solid under ordinary conditions, by applying heat continuously we first liquefy and ultimately vapourize them.
The sparks fly out, the bellows ply, As if the rock to liquefy. The fire and water's might twofold Are here united found; The mill-wheel, by the flood seized hold, Is whirling round and round; The works are clattering night and day, With measured stroke the hammers play, And, yielding to the mighty blows, The very iron plastic grows.
The glands form tumours of variable size, and are often larger than the primary growth, the characters of which they reproduce. The glands are at first movable, but soon become fixed both to each other and to their surroundings; when fixed to the mandible they form a swelling of bone-like hardness; in time they soften, liquefy, and burst through the skin, forming foul, fungating ulcers.
Now the grub of the Anthrax "appears precisely at the exact moment when the larva of the Chalicodoma is attacked by that lethargy which precedes metamorphosis, and which renders it insensible, and during which the substance of the grub about to be transfigured into a bee commences to break down and resolve itself into a liquid pulp, for the processes of life always liquefy the grub before achieving the perfect insect."
It results from this that the temperature becoming gradually lower as we rise in the atmosphere, at a certain altitude there can no longer remain any traces of oxygen or nitrogen, which no doubt liquefy, and the atmosphere must be almost exclusively composed of the most volatile gases, including hydrogen, which M.A. Gautier has, like Lord Rayleigh and Sir William Ramsay, proved to exist in the air.
The discovery of these properties suggested an explanation of the failure of previous attempts to liquefy air. Air at ordinary low temperatures is in the gaso-liquid condition, and its liquefaction is not possible except when a difference exists between the density of the vapor and that of the liquid greater than it is possible to produce under any conditions that can exist then.
Metellus accepted the proposal and wrote to him to come, on which Pompeius entering Gaul, performed noble exploits, and he also fanned into a flame again and warmed the warlike and courageous temper of Metellus, which was now near becoming extinct through old age, as the liquid, heated stream of copper by flowing about the hard, cold metal is said to soften and to liquefy it into its own mass better than the fire.
Better still: I can feed them quite satisfactorily with wasps that have turned putrid under their horny rings; I see them greedily suck the juices of decomposing Rosechafer grubs; I can keep them thriving with chopped up butcher's meat, which they know how to liquefy by the method of the common maggot.
M. Cailletet, having fruitlessly subjected air and hydrogen to a pressure of one thousand atmospheres, came to the conclusion that it was impossible to liquefy those gases at the ordinary temperature by pressure alone.
