That is, the greater will be the number of those who are the servants and not the masters of science. A unity of a certain kind we shall have, the unity of those who have learned to pilot an aeroplane, to apply X-rays, to extract the phosphate from iron, or to test cattle for tubercle.
If the cancer already covers an extensive area, or has invaded the cavity of the orbit or nose, radium or X-rays yield the best results. The effect is soon shown by the ingrowth of healthy epithelium from the surrounding skin, and at the same time the discharge is lessened.
Returning to the Hippocratic collection, the purely surgical treatises will be found no less remarkable than those of clinical observation. The verdict of Adams was probably just, though since his time the surgery of dislocations, aided especially by X-rays, has been enabled to pass very definitely beyond the Hippocratic position.
Occasionally a small thrombus situated behind a valve in a varicose vein or in the terminal end of a dilated vein for example in a pile undergoes calcification, and is then spoken of as a phlebolith; it gives a shadow with the X-rays.
Every schoolboy is now aware that a door is solid only to his eyes and touch; that with the aid of X-rays it becomes transparent, the light passing through it as water passes through network, revealing what is on the other side. Every schoolboy also knows that his own body can be so photographed as to reveal its skeleton.
It will depend upon the subsequent course of the disease, whether or not a second, or it may be even a third, application of radium will be required. Where neither radium nor X-rays is available or applicable, recourse may be had to the injection of Coley's fluid, a preparation containing the mixed toxins of the streptococcus of erysipelas and the bacillus prodigiosus; or of selenium.
Whatever is so small that we cannot handle it is too small to be seen. Whatever is too distant to be reached is not truthfully reported. The "X-rays" of light we cannot see, because our ancestors could not deal with them. The sun and stars, the clouds and the sky are not at all what they appear to be. The truthfulness of the senses fails as the square of the distance increases.
Hilary echoed inquiringly. "Yes. They act like X-rays, more powerful though, and with the further property of rendering everything they touch transparently crystal for depths of ten to fifteen feet. Lead is the only element they can not penetrate. Another secret our scientists can not fathom, so they talk learnedly about the stream of rays polarizing the structure of matter along a uniaxis."
Taking crystals of this chemical compound, he spread the same over a cloth or paper screen, and used that screen to catch and convert the invisible images carried against it by the X-rays. To his surprise, his experiment was completely successful.
Other forms of sarcoma, and the enlargement of an accessory thyreoid, are less likely to be confused with tuberculous glands. Calcified tuberculous glands give definite shadows with the X-rays.
