Still, in spite of Biddy and Monny and the others, and not for them, my heart beat fast when, on the afternoon of the third day out from Naples, the ship brought us suddenly in sight of something strange. We were moving through a calm sea, more like liquefied marble than water, for it was creamy white rather than blue, veined with azure, and streaked, as marble is, with pink and gold.
When bile finds a means of discharge, it boils up and sends forth all sorts of tumours; but when imprisoned within, it generates many inflammatory diseases, above all when mingled with pure blood; since it then displaces the fibres which are scattered about in the blood and are designed to maintain the balance of rare and dense, in order that the blood may not be so liquefied by heat as to exude from the pores of the body, nor again become too dense and thus find a difficulty in circulating through the veins.
Here are antique mosaics, in which colored stones seem liquefied, realizing the most beautiful effects of painting quadrigae, warriors, arms, armor, vases, streams, all lifelike. Ascending to the hall of French paintings I spent an hour in studying one picture La Meduse, by Gericault. It is a shipwrecked crew upon a raft in mid ocean.
They are made of liquefied electricity. We take the electric current, liquefy it, then solidify it, then mould it into the form of a sphere. Inside we place a little gong, that begins to ring as soon as the ball lands. The electricity in it is what makes it fly so rapidly and so far, and even you mortals know the principle of the electric bell."
If we could deepen these cavities to the extent of a thousand miles, the pressure would become so great that if the pit were kept free from the heat of the earth the gaseous materials would become liquefied.
"Nothing so clumsy as that, I hope," he murmured gently. "I will not insult a person of your experience and intelligence by enumerating the various ways in which the seal of a dispatch may be liquefied. It is quite true that I have read with much pleasure the letter which you are carrying from a certain group of very distinguished men to a certain person now in The Hague.
But an image of the stricken and scattered mind of the man should, though deficient in the attraction, have a greater significance, forasmuch as it does not exhibit him entirely liquefied and showered into space; it leaves him his legs for the taking of further steps.
I said that a portion of the sunbeam was stopped by the ice and liquefied it. What is this portion? The dark heat of the sun. The great body of the light waves and even a portion of the dark ones, pass through the ice without losing any of their heating power. When properly concentrated on combustible bodies, even after having passed through the ice, their burning power becomes manifest.
All were possessed by the same thought to hasten to the corral and set at liberty the animals it enclosed. Before three in the morning they arrived at the corral. The cries of the terrified musmons and goats indicated the alarm which possessed them. Already a torrent of burning matter and liquefied minerals fell from the side of the mountain upon the meadows as far as the side of the palisade.
Something, then, must be done to insulate the liquefied gas, else it will retain the liquid state for too short a time to be much experimented with. How might such insulation be accomplished? The most successful attack upon this important problem has been made by Professor Dewar.
