The experiment with the iron filings introduces a new idea into the mind; the idea, namely, of structural arrangement. Every pair of filings possesses four poles, two of which are attractive and two repulsive. The attractive poles approach, the repulsive poles retreat; the consequence being a certain definite arrangement of the particles with reference to each other. Theory of Crystallization.
But their testimony to its nutritiousness is worth nothing, for they will eat pine knots, or anthracite coal, or brass filings, or lead pipe, or old bottles, or anything that comes handy, and then go off looking as grateful as if they had had oysters for dinner. Mules and donkeys and camels have appetites that anything will relieve temporarily, but nothing satisfy.
Naturally, for I had planned the distance well, his finger-tips, white with the chalk he had unconsciously handled, touched the blue surface of the blotter now lying uppermost and left their marks there. I could have shouted in my elation at the success of this risky maneuver, but managed to suppress my emotion, and to stand quite still while he took a good look at the filings.
Their direction shows us the direction of the magnetic forces, and their density shows us the strength of the magnetic forces; for where the force is strongest there we have the lines of force most numerous and most strongly delineated in the scattered filings.
"Comrades!" resounded Pavel's voice, ringing and firm. A dry, hot haze burned the mother's eyes, and with a single movement of her body, suddenly strengthened, she stood behind her son. All turned toward Pavel, and drew up to him, like iron filings attracted by a magnet. "Brothers!
There, too, was the famous iron crown of Lombardy, which Austria still claims as her own; so called from a thin ring of iron inserted in it, made from a nail of the true cross which Gregory had sent Agilwulf; just as he sent Childebert, the Frankish king, some filings of St. Peter's chains; which however, he says, did not always allow their sacred selves to be filed.
If their advice is to be of value, physicians should know the various methods of treatment suitable for dental diseases, including mouth washes, gargles, masticatories, anointments, rubbings, fumigations, cauterizations, fillings, filings, and the various manual operations.
At the end of one of the work-rooms, backed against a snowy window, clung about with shreds of the driving storm, stood Ellen Brewster, with some other girls around her, and a few men on the outskirts, and a steady, curious movement of all the other workmen towards her, as of iron filings towards a magnet, and she was talking. Her voice was quite audible all over the great room.
There was more cotton than silk in the velvet covering of the furniture; and if various statuettes placed on brackets at a certain height had been closely inspected, it would have been found that they were of mere plaster, hidden beneath a coating of green paint, sprinkled with copper filings.
Now that her vigil was explained, for Bower had advanced with ready smile and outstretched hand, the Wraggs and Vavasours and de la Veres all the little coterie of gossips and scandalmongers were drawn to the center of the hall like steel filings to a magnet. Millicent ignored Bower. She was young enough and pretty enough to feel sure of her ability to deal with him subsequently.
