“When 88° is reached, the boundary between liquid and gas vanishes; liquid and gas have blended into one mysterious intermediate fluid; an indefinite fluctuating something is there filling the whole of the tube—an etherealized liquid or a visible gas. Hold a red-hot poker between your eye and the light; you will see an upflowing wave of movement of what appears like liquid air. The appearance of the hybrid fluid in the tube resembles this, but is sensibly denser, and evidently stands between the liquid and gaseous states of matter, as pitch or treacle stands between solid and liquid.”
The temperature at which this occurs has been named by Dr. Andrews the “critical temperature”; here the gaseous and the liquid states are “continuous,” and it is probable that all other substances capable of existing in both states have their own particular critical temperatures.
Speculating further upon this “critical” state, Mr. W. Mattieu Williams emits some quite Occult theories about Jupiter and other Planets. He says:
“Our notions of solids, liquids, and gases are derived from our experiences of the state of matter here upon this Earth. Could we be removed to another planet, they would be curiously changed. On Mercury water would rank as one of the condensible gases; on Mars, as a fusible solid; but what on Jupiter?
“Recent observations justify us in regarding this as a miniature sun, with an external envelope of cloudy matter, apparently of partially-condensed water, but red-hot, or probably still hotter within. His vaporous atmosphere is evidently of enormous depth, and the force of gravitation being on his visible outer surface two-and-a-half times greater than that on our earth's surface, the atmospheric pressure, in descending below this visible surface, must soon reach that at which the vapour of water would be brought to its critical condition. Therefore we may infer that the oceans of Jupiter are neither of frozen, liquid, nor gaseous water, but are oceans, or atmospheres of critical water. If any fish or birds swim or fly therein, they must be very critically organized.”
As the whole mass of Jupiter is 300 times greater than that of the Earth, and its compressing energy towards the centre proportional to this, its materials, if similar to those of the Earth, and no hotter, would be considerably more dense, and the whole planet would have a higher specific gravity; but we know by the movement of its satellites that, instead of this, its specific gravity is less than a fourth of that of the Earth. This justifies the conclusion that it is intensely hot; for even hydrogen, if cold, would become denser than Jupiter under such pressure.
“As all elementary substances may exist as solids, liquids, or gases, or, critically, according to the conditions of temperature and pressure, I am justified in hypothetically concluding that Jupiter is neither a solid, a liquid, nor a gaseous planet, but a critical planet, or an orb composed internally of associated elements in the critical state, and surrounded by a dense atmosphere of their vapours and those of some of their compounds such as water. The same reasoning applies to Saturn and other large and rarefied planets.”
It is gratifying to see how “scientific imagination” approaches every year more closely to the borderland of our Occult Teachings.
This is corroborated by a learned Brahman. In his most excellent Lectures on the Bhagavad Gîtâ (Theosophist, April, 1887, p. 444) the lecturer says:
“There is a peculiarity to which I must call your attention. He [Krishna] speaks here of four Manus. Why does he speak of four? We are now in the seventh Manvantara—that of Vaivasvata. If he is speaking of the past Manus, he ought to speak of six, but he only mentions four. In some commentaries an attempt has been made to interpret this in a peculiar manner.
