It is all a groping and ignorant effort to construct out of base metal and brass filings, so to speak, something to take the place of that golden treasure denied them by Nature, a child. But this is a digression.
When we place a thin sheet of cardboard or glass upon a magnet and scatter iron filings over it, we observe the iron to take certain positions and trace certain lines which Faraday has styled lines of magnetic force, or, more simply, lines of force. The figure, as a whole, which is thus formed constitutes a magnetic phantom.
Leather gearing spun along with a continuous gliding, and there was ceaseless bustle and activity amidst the odoriferous dampness of all the steam. Scores of perspiring workmen, grimy with dust and filings, were still toiling. Still this was the final effort of the day.
"That wouldn't take no crowd," Happy Jack grumbled, remembering the limitations of Dry Lake's hotel. "Here come Chip and the missus. Wonder what they want?" The Little Doctor left Chip to get their tickets and walked quickly toward them. "Hello, boys! Waiting for someone, or just going somewhere?" "Waiting. Same to you, Mrs. Chip," Weary replied. "To me? Well, we're going up to make our filings.
Loeb all he did was to restate destiny, one of humanity's oldest ideas, in the terms of tropisms, infusoria and light. Omar Khayyam chemically reincarnated in the Rockefeller Institute. Nevertheless those who accept his theories have to admit that there is essentially no difference between their impulses and the rush of filings toward a magnet.
On asking if M. Thomas Froment were there, Pierre was led by an old workman to a little shed, where he found the young fellow in the linen jacket of a mechanician, his hands black with filings. He was adjusting some piece of mechanism, and nobody would have suspected him to be a former pupil of the Lycee Condorcet, one of the three clever Froments who had there rendered the name famous.
To this pond, for open water was very, very scarce on the prairie in September, came water fowl from near and afar; from no man knew where. As steel filings respond to a magnet, they came, and as inevitably; stragglingly, suspiciously by day, in flocks that grew to be a perfect cloud by night.
There seems no doubt that Paracelsus discovered many facts which became of great importance in chemistry: he prepared the inflammable gas we now call hydrogen, by the reaction between iron filings and oil of vitriol; he distinguished metals from substances which had been classed with metals but lacked the essential metalline character of ductility; he made medicinal preparations of mercury, lead and iron, and introduced many new and powerful drugs, notably laudanum.
She cannot be a martinet nor, in her presence, can the children become sycophants. Her very presence generates an atmosphere that is conducive to healthy growth. There is that impelling force about her that draws people to her as iron filings are drawn to the magnet. Her smile stills the tumult of youthful exuberance and when the children look at her they gain a comprehensive definition of a lady.
The process was slow, as the gas had to be generated in large quantities by means of diluted sulphuric acid and iron filings put into wooden casks disposed round a large cistern, from which it was conveyed through water in long leaden pipes. To keep the impatient populace quiet, therefore, during the tedious operation, Montgolfier sent up one of his fire-balloons.
