"My!" he said, "but I've got an appetite. I could scoff iron-filings an' horseshoe nails an' thank you kindly, ma'am, for a second helpin'." He straightened up, and, while he reached for matches in the pocket of his overalls, his eyes traveled across the pool to the side-hill. His fingers had clutched the match-box, but they relaxed their hold and the hand came out empty.
He unpacked his food and got out frying-pan and coffee-pot. He gathered an armful of dry wood, and with a few stones made a place for his fire. "My!" he said, "but I've got an appetite. I could scoff iron-filings an' horseshoe nails an' thank you kindly, ma'am, for a second helpin'."
They are simply thrown there by the handful and the shovelful, as it were, like so many pebbles or bits of chalk. But the behavior of the white cells goes far beyond this. We are almost tempted to endow them with volition, though they are of course drawn or driven by chemical and physical attractions, like iron-filings by a magnet, or an acid by a base.
While our landlady was on the premises, I took occasion to invite her up to my own room, with a view of seeing whether my mattress of pebbles and iron-filings could be supplemented by another of shavings or straw, or some material less provocative of bodily injuries.
The 'body' was iron-filings, the acid sulphuric acid, and the vapour nitrogen. The other 'new kinds of air' were the gases discovered by Priestley. I do not wonder at Johnson's displeasure when the name of Dr. Priestley was mentioned; for I know no writer who has been suffered to publish more pernicious doctrines. I shall instance only three.
Or you may lay a little heap of iron-filings on a sheet of paper with a magnet beneath it, and they will be quiet enough as they are, but give the paper a slight jar and the specks of metal will suddenly find their way to the north or the south pole of the magnet and take a definite shape not unpleasing to contemplate, and curiously illustrating the laws of attraction, antagonism, and average, by which the worlds, conscious and unconscious, are alike governed.

Of all the horde of adventurous characters who were drawn to the Continent on the outbreak of war as iron-filings are attracted by a magnet, I doubt if there was a more picturesque figure than a little photographer from Kansas named Donald Thompson. I met him first while paying a flying visit to Ostend.
We have several tests for oxygen besides the mere burning of bodies. You have seen a candle burnt in oxygen, or in the air; you have seen phosphorus burnt in the air, or in oxygen; and you have seen iron-filings burnt in oxygen. But we have other tests besides these, and I am about to refer to one or two of them for the purpose of carrying your conviction and your experience further.
The power of attraction which the ovum exerts may be likened, most simply, to the influence of a magnet upon iron-filings. While there has been no opportunity to observe such attraction between the parent cells of human beings, its existence is not open to doubt.
