Radium acts upon the chemical constituents of glass, porcelain and paper, giving them a violet tinge, changes white phosphorous into yellow, oxygen into ozone and produces many other curious chemical changes. We have said that it can serve the surgeon in physical examinations of the body after the manner of X-rays.
This young man is then commanded to stand apart, the girl is hunted out, and together they wait while the witch-doctor X-rays them through and through. After this close scrutiny, they are asked: "Do you want this man?" "Do you want this girl?" To which they reply, "Yes, Father of Kittens, I do." It may be a great surprise to the reader to learn that these savages are exceedingly moral.
Yet there were differences, for there was none of that misty halo around the bones, the flesh which the X-rays cannot render wholly invisible. The skeletons stood out clean cut, with no trace of fleshly vestments. I crept over, spoke to the two. "Don't look up yet," I said. "Don't open your eyes. We're going through a queer light. It has an X-ray quality. You're going to see me as a skeleton "
It consists simply of a closed box with an opening to which the eyes are placed. The opposite end of the box is a piece of board coated with a salt such as platino-barium cyanide. When the X-ray strikes this salt it makes it glow, or fluoresce, and objects held between the X-ray tube and the fluoroscope cast shadows according to the density of the parts which the X-rays penetrate.
If in the interior, a sufficient amount of the cortex should be removed to allow of the tumour being scraped out, and care must be taken that no nodules of cartilage are left behind. In multiple chondromas of the hand, when the fingers are crippled and useless, exposure to the X-rays should be given a trial, and in extreme cases the question of amputation may have to be considered.
Through the lead-glass bowl I could see the X-ray tube inside suffused with its peculiar, yellowish-green light, divided into two hemispheres of different shades. That, I knew, was the cathode ray, not the X-ray, for the X-ray itself, which streams outside the tube, is invisible to the human eye. The doctor placed in our hands a couple of fluoroscopes, an apparatus by which X-rays can be detected.
For instance, as every student of physics knows, a single point of space may contain at the same time vibrations of heat, light of many shades, magnetism electricity, X-Rays, etc., each manifesting its own rate of vibration, land yet none interfering with the others."
The bones show a feeble shadow with the X-rays, and appear thin and atrophied; the medullary canal is increased at the expense of the cortex. In young infants in whom multiple fractures occur the prognosis as to life is unfavourable, and no satisfactory treatment of the disease has been formulated. If the patient survives, the tendency to fracture gradually disappears.
If a versatilist, a modern Goethe, for instance, could put all of Emerson's admonitions into practice, a constant permanence would result, an eternal short-circuit a focus of equal X-rays. Even the value or success of but one precept is dependent, like that of a ball-game as much on the batting-eye as on the pitching-arm. The inactivity of permanence is what Emerson will not permit.
