The fact that they are found embedded in these iron meteorites is another argument in favor of the hypothesis of the solar or stellar origin of the latter. To appreciate this it is necessary to recall the way in which Moissan made his diamonds. It was by a combination of the effects of great heat, great pressure, and sudden or rapid superficial cooling on a mass of iron containing carbon.
Twenty-eight large wires are necessary to bring it; I own the power-plant, ostensibly for the operation of a small sugar refinery. I may add that the furnace is a variation of the principle employed by Professor Moissan, in Paris." He turned to Mr. Czenki. "You may remember having heard me mention him?" "I remember," the expert acquiesced grimly.
Plunged into the frightful cold of space, their surfaces are quickly cooled, as Moissan cooled his prepared iron by throwing it into water, and thus the requisite stress is set up within, and, as the iron solidifies, the included carbon crystallizes into diamonds.
"It cannot be, surely it cannot be," said Professor Moissan at length. "But it is," said another member of the party. "Are these diamonds?" asked a third. "I cannot yet tell," replied the Professor. "They have the brilliancy of diamonds, but they may be something else." "Moon jewels," suggested a third. "And worth untold millions, whatever they are," remarked another. Jewels from the Moon.
Here, besides several leading men of science from our own country, were Lord Kelvin, Lord Rayleigh, Professor Roentgen, Dr. Moissan the man who first made artificial diamonds and several others whose fame had encircled the world. Each of these men cherished hopes of wonderful discoveries, along his line of investigation, to be made in Mars.
"Now, then," continued Pylotte, with an unconscious display of enthusiasm; "while diamonds certainly have been made by artificial means, the great difficulty has been that of producing them at a low cost. Moissan, in my country, produced diamonds by heating charcoal and iron to a high degree, and letting the mixture cool under enormous pressure.
Fortunately this number did not include any of those whom I have had occasion to mention in the course of this narrative. The venerable Lord Kelvin, who, notwithstanding his age, and his pacific disposition, proper to a man of science, had behaved with the courage and coolness of a veteran in every crisis; Monsieur Moissan, the eminent chemist; Prof.
The venerable Lord Kelvin, who, notwithstanding his age, and his pacific disposition, proper to a man of science, had behaved with the courage and coolness of a veteran in every crisis; Monsieur Moissan, the eminent chemist; Professor Sylvanus P. Thompson, and the Heidelberg professor, to whom we all felt under special obligations because he had opened to our comprehension the charming lips of Aina all these had survived, and were about to return with us to the earth.
Then, thought I, such a stone could scarcely exist without being mentioned in every book on gems, and again I called to mind the stories of contraband and light-fingered Kaffirs at the Cape. I put the question of purchase on one side. "How did you get it?" said I. "I made it." I had heard something of Moissan, but I knew his artificial diamonds were very small. I shook my head.
Edison travelled was, of course, the flagship of the squadron, and I had the good fortune to be included among its inmates. Here, besides several leading men of science from our own country, were Lord Kelvin, Lord Rayleigh, Professor Roentgen, Dr. Moissan the man who first made artificial diamonds and several others whose fame had encircled the world.
