Bronze, for example, took some thousands of years to permeate the continent of Europe; iron perhaps as many hundreds; platinum a little more than fifty years; and radium less than five. What we do get from this material evidence, however, is a quite indisputable sequence of styles in time in each locality where we can hit upon stratified remains.
Radium causes a reaction in the tissues attended with exudation from the vessels, for the escape of which provision must be made. If radium is not available, the affected area is repeatedly exposed to the action of the X-rays as soon as the wound has healed. The employment of these measures has diminished to a remarkable degree the recurrence of sarcoma after operation.
"Some liquid that is intensely radioactive; but what it is I know not at all. Upon the living skin it acts like radium raised to the nth power and with an element most mysterious added. The solution with which I treated him," he pointed to Huldricksson, "I had prepared before I came here, from certain information I had.
Suppose it were ascertained that every child in the world could be rendered absolutely immune from all disease during its entire life by taking half an ounce of radium to every pint of its milk. The world would be none the healthier, because not even a Crown Prince no, not even the son of a Chicago Meat King, could afford the treatment.
Where Mike, violently transplanted from Wrykyn, saw only a wretched little hole not to be mentioned in the same breath with Wrykyn, Adair, dreaming of the future, saw a colossal establishment, a public school among public schools, a lump of human radium, shooting out Blues and Balliol Scholars year after year without ceasing.
"I guess you'd better go now," said Virginia discreetly, and continued her vigil alone. Death Valley was harmless, but when he began hearing things there was no telling where he would stop. The next minute he would be seeing things, and then getting messages, and then looking through mountains with radium.
By means of a magnifying glass, a screen covered with sulphide of zinc is kept under observation, and in front of it is disposed, at a distance of about half a millimetre, a fragment of some salt of radium. We then perceive multitudes of brilliant points on the screen, which appear and at once disappear, producing a scintillating effect.
Its salts are luminous in the dark, but this luminosity, at first very bright, gradually diminishes as the salts get older. We have here to do with a secondary reaction correlative to the production of the emanation, after which radium undergoes the transformations which will be studied later on.
Both will penetrate many different kinds of matter, but it needs reflection or refraction to make visible an object on which it impinges. Understand?" "Hardly," I answered dubiously. "What kind of visible light is there, if not radium or the Röntgen ray? You can photograph with either, can't you?" "Yes, but to see what you have photographed you must develop the film.
It's been found in places, but not in much bigger quantities than would dope a fair-sized litter of piebald kittens. It's sort of like radium, and half a pint of the distilled drug would be worth over twenty-five thousand dollars. Maybe that'll tell you how much there is of it on the market. But it's not that. Oh, no, it's a heap bigger than that, boy.
