Roentgen has familiarized us with an order of vibrations of extreme minuteness as compared with the smallest waves with which we have hitherto been acquainted; and there is no reason to suppose that we have here reached the limit of frequency.
These are easily checked by material obstructions, although they render the air a conductor and affect photographic plates. The third are very penetrating rays, which are not deflected by electricity and which are seemingly identical with Roentgen rays.
Of course with all this the one question is as to whether such conceptions are true; but judged by intuition, which is the Roentgen ray of spirit judged by the data reached by scholars and thinkers, by psychologists and scientists it has no claim to recognition.
Within but a few years we have made such discoveries as two centuries ago would have sent the discoverer's to the flames. The liquefaction of oxygen; the existence of radium, of helium, of polonium, of argon; the different powers of Roentgen and Cathode and Bequerel rays.
It seemed to March an ironical outcome of all this spiritual severity that one of the greatest modern scientific discoveries should have been made in Wurzburg, and that the Roentgen rays should now be giving her name a splendor destined to eclipse the glories of her past. Mrs.
Between two hundred and four hundred millions of millions of vibrations of ether per second are the different sorts of heat. Between four hundred and eight hundred vibrations are the different colors of light. Beyond eight hundred vibrations there is plenty of light, invisible to our eyes, known as chemical rays and probably the Roentgen rays.
Here, besides several leading men of science from our own country, were Lord Kelvin, Lord Rayleigh, Professor Roentgen, Dr. Moissan the man who first made artificial diamonds and several others whose fame had encircled the world. Each of these men cherished hopes of wonderful discoveries, along his line of investigation, to be made in Mars.
Riesener, Roentgen, Gouthiére, Fragonard and Boucher are some of the names that stand out most distinctly as authors of the beautiful decorations of the time. Marie Antoinette's boudoir at Fontainebleau is a perfect example of the style and many of the other rooms both there and at the Petit Trianon show its great beauty, gayety and dignity combined with its richness and magnificence.
The late revelations of chemistry, Roentgen rays, x-rays, radio-activity of metals, etc., throw an interesting light upon the seemingly infinite divisibility of matter. A small particle of a given substance may for many years throw off a continuous shower of corpuscles without perceptibly diminishing its volume. For an illustration we may take the odoriferous musk.
First of all it was subjected to the Roentgen rays, the result being to show that the interior was not homogeneous. A few days after, there was a great gathering of experts at the Museum, a hole was cut in the wax at the back of the bust, a bent wire was introduced, and the search for the famous piece of waistcoat began.
