By acting with Roentgen rays on the region where the ovaries lie, Steinach and his colleague Holzknecht brought about all the symptoms of pregnancy, development of teats and milk glands, secretion of milk, and great growth of the uterus in all its layers.
The operating rooms, kitchens, wards, rooms for operating by Roentgen rays, and even a chapel have been installed. The organization and system are of the highest order. Every one in it is American. The doctors are the best in Paris. The nurses and orderlies are both especially trained for the work and volunteers. The spirit of helpfulness and unselfishness is everywhere apparent.
Unfortunately, of all the sickly climates of Africa, this is perhaps the most pestilential, and Mr. Nicholls, before commencing his journey, fell a victim to the epidemic fever. Another German named Roentgen, recommended also by Blumenbach, undertook to penetrate into the interior of Africa by way of Morocco.
"That light wasn't exactly the Roentgen variety," Drake interrupted my absorption in our surroundings. "And I hope to God it's as different as it seemed. If it's not we may be up against a lot of trouble." "More trouble than we're in?" I asked, a trifle satirically. "X-ray burns," he answered, "and no way to treat them in this place if we live to want treatment," he ended grimly.
But although this action is analogous to the Roentgen rays, at least as regards its action upon the photographic plate and its influence on the electric field, its action is extremely feeble in comparison, the Roentgen rays producing effects in minutes, or even seconds, which require days of exposure to uranium rays.
Many investigators have found that the Roentgen rays destroy the spermatic cells of the testis in Mammals, leaving the cells of Sertoli, the interstitial tissue, nerves, and vessels uninjured. G. d. Roy. It seems possible, although no such suggestion has been made, that the interstitial cells might either normally or exceptionally give rise to ova and spermatocytes.
Serviss pictures the gathering together of the most famous scientists of the day Edison, Roentgen, Lord Kelvin and others. The Martian machines and weapons left behind are dismantled; their principles of operation are discovered and duplicated; and a defense against their forces is perfected.
He found that if a plate covered with a phosphorescent substance is placed near a discharge tube exhausted so highly that the cathode rays produced a green phosphorescence, this plate is made to glow in a peculiar manner. The rays producing this glow were not the cathode rays, although apparently arising from them, and are what have since been called the Roentgen rays, or X-rays.
March could not allow that they would do so; or at least that the name of Roentgen would ever lend more lustre to his city than that of Longfellow's Walther von der Vogelweide. She was no less surprised than pleased to realize that this friend of the birds was a Wurzburger, and she said that their first pilgrimage in the morning should be to the church where he lies buried.
The wonderful shadow pictures produced on the phosphorescence screen, or the photographic plate, would seem to come from some peculiar form of light, but the exact nature of these rays is still an open question. Whether the Roentgen rays are really a form of light that is, a form of "electro-magnetic disturbance propagated through ether," is not fully determined.
