"You'd be bound to learn it. D'you know what the dinies' teeth are made of?" "It's been said," said President O'Hanrahan, "that it's bor ... boron carbide in organic form. What that means I wouldn't know, but we've got a fine crop of it!" "It's the next hardest substance to diamond," said the committeeman dourly. "It's even been guessed that an organic type might be harder.
He was enthralled by the activity in the blockhouse, and, careful to keep out of the way, he walked from station to station. Now and then he looked through the thick glass ports, and he saw the green mist of boron hydride as fuel throbbed slowly into the rocket's tanks. A thin, bald scientist in a scarlet sports shirt picked up a microphone and spoke into it.
The greater part of the legends of the Saint Graal that sprang out of the work of Robert de Boron were probably woven together by his genius; and were used in the great strife to prove that the English Church originated independently of Rome.
Rowland adds: "The substances under the head of 'Not in the Solar Spectrum' are often placed there because the elements have few strong lines or none at all in the limit of the solar spectrum when the arc spectrum, which I have used, is employed. Thus, boron has only two strong lines at 2497. Again, the lines of bismuth are all compound, and so too diffuse to appear in the solar spectrum.
I go to Paris, then to my villa at Mont Boron. I have the nostalgia of my own country, you see. Then to Venice at Easter." I Paul looked at her wistfully, for life seemed suddenly very blank and dismal. "What shall I do all that time without my best friend?" "You will probably find another and forget her."
In fact, diny teeth, being organic, seemed to be an especially hard form of boron carbide. Dinies could chew iron. They could masticate steel. They could grind up and swallow anything but tool-steel reinforced with diamond chips. The same amateur chemist worked it out that the surface soil of the planet Eire was deficient in iron and ferrous compounds. The dinies needed iron. They got it.
Why had she left her convent, if not at the instigation of the merry-eyed, devil-may-care Bindo? Around Mont Boron and down into Villefranche we went, until around the sudden bend, close to the sea-shore, showed the great white façade of the Bristol at Beaulieu, that fine hotel so largely patronised by kings, princes, and other notabilities.
In like manner silicon-eisen, containing 9 per cent. of silicon, was treated, but not giving so satisfactory a result. A small quantity only of silicon separates in the uncombined form, the greater quantity separating in the form of silica, SiO , the amorphous silicon so obtained apparently being more prone to oxidation than the boron so obtained.
"But, Martha, can you be really sure? You know, by now, that learning to read this language is as important to me as it is to you, but how can you be so sure that those words really mean things like hydrogen and helium and boron and oxygen? How do you know that their table of elements was anything like ours?" Tranter and Penrose and Sachiko all looked at him in amazement.
On the same principle that electro-dissolution is used for the estimation of combined carbon in steel, etc., I have lately varied the experiment by introducing, instead of steel, iron containing a certain percentage of boron, and, having connected the respective boride with the positive pole of a powerful battery, and to the negative a plate of platinum, using as a solvent dilute sulphuric acid, I observed, after the lapse of about twelve hours, the iron had entirely passed into solution, and a considerable amount of brownish precipitate had collected at the bottom of the vessel, intercepted by flakes of graphite and carbon; the precipitate, having been collected on a filter paper, washed, and dried, on examination proved to be amorphous boron, containing graphite and other impurities, which had become chemically introduced during the preparation of the boron compound.
