Ames Intelligencer (Newspaper) - March 5, 1896, Ames, Iowa The Ray of mystery. Development of Roentgen a discovery. Its uses and possibilities. Photographs made through metals two years ago. Its Peculiar properties were All set Forth to the scientific world Early in 1894. Not much better understood now than it was then the part. Tesla a converter plays in recent experiments. Copyright 1896, by the author new York feb. 28.�?probably no such popular furore for a purely scientific discovery was Dver excited before us has grown out of the exploitation of Tho new photography with the Aid of the x Ray or Roentgen Ray As it is popularly known. How Many intelligent and Well educated men and women know or knew a month ago what a cathode is or was yet the name cathode dates Back to the time of Faraday 1832. The cathode Ray Bas been known for More than 15 years. Photography with the cathode Ray is More than two years old. In View of the excitement created All Over the world by the experiments made by scientists in the last two months the a fac seem remarkable. They Are beyond question though and i have seen the pictured results of cathode photography the product of the experiments of professor Philipp Lenard of Germany published in March 1894. Lenard a discoveries awakened the scientific world to investigation. Roentgen was one of the investigators. It happened to be the Good Fortune of remt entry the receptacle the anode the producer and disseminator of Light. In the Brilliant rays which streamed from the positive pole the negative pole was thrown completely in Shadow until Hittorff and Crookes almost simultaneously discovered that it too propagated a Ray. Crookes achievements. Crookes achievements in the direction of producing a vacuum resulted in the Crookes tubes which have become famous popularly As Well As scientifically of late because of their use in cathode photography. It was in one of his vacuum tubes that Crookes hunted Down the cathode Ray or As a recent scientific writer puts it,4vitalized�?� the my for the Benefit of the Royal society and the British association in 1879. In Tho scientific world the discovery was regarded As of grave importance and the scientific journals made much of it. But if there was any mention of it in the daily or weekly newspapers it must have been very Brief and to the Reader of unscientific mind must have seemed very uninteresting for who by the widest stretch of the imagination could have associated the fact that a Ray of some kind imperceptible to the Eye under Ordinary conditions proceeded from the negative pole of a vacuum tube with the possibility of photographing the human brain certainly Crookes did not and it was not until 1891 that the discovery was made that these Peculiar rays would penetrate solids. Wiedemann and Ebert noticed in that year that Gold Leaf coatings on vacuum tubes were transparent to the cathode rays. This fact being made known to the scientific world was developed by the late professor Hertz whose assistant was pro Fessor Philipp Lenard. Professor Lenard became deeply interested in this Peculiar property of the cathode Ray and made Earnest efforts to classify the Ray forming a theory that it was of eth Eric nature and Basing his experiments on that idea. Up to the time of his experiments the rays had been studied Only in the vacuum. The Glass of the vacuum tube seemed impervious to them. Professor Lenard wanted to get them into the air. With other scientific men he believed that they could not be led through Glass and he did not know that they would pass into the air but their ability to penetrate Metal seemed to offer a Means of leading them without the tube. Professor Hertz suggested the use of an aluminium window to bring the Waves of electrified air a photography through opaque substances might have been known before for Nikola Tesla tells me be has found that these a a sound Waves of electrified air will make impressions on dry plates like the cathode rays. But sound Waves Are not supposed to take photographs and it would have been beyond All reason to expect it of them. The cathode rays illuminated very faintly but perceptibly. It was natural for the experimenter to test their effect on the photographic plate and on sensitive paper for the purpose of creating an analogy Between them and the rays of Light which come to us As Illus Winants but which unlike the cat Bode rays will not pass through opaque substances. The cathode Ray was not Light but it produced this one effect of Light at least it decomposed the chemicals on the dry professor Roentgen. Gen to discover the Means of making a popular application of the discovery of Lenard and of Lenard a predecessors Crookes Hittorff and others. For this reason Roentgen is a popular hero and Lenard is ignored. But the scientific world gives Lenard the credit which is his due and if he is not a person of narrow mind he is no doubt Content with that. Nikola Tesla who believes he came very near a somewhat similar discovery smiles when he Speaks of the Public excitement Over the cathode photography and says everything will find its place when history is written. Or. Tesla has a Large interest even now in the development of Tho famous discovery for the Tesla converter is used universally to produce those powerful rays with which Roentgen was Able to accomplish what would have been impossible to Lenard without the Tesla apparatus. In fact but for Tesla a invention there would have been no photographing of the Bones of the hand. Lenard never got beyond the Point of making Tho rays penetrate pieces of Metal foil. If Yon have Ever been in a scientific class and studied electricity you know the Leyden Jar with los brass Knob from which Sparks of electricity pass when it is brought close to a conductor provided Tho Jar is charged. This is Static electricity or electricity which can to produced by Ordinary friction. It was the first electricity known. Probably also you remora Nikola Tesla. Ber the tube in which electricity was made to pass from the positive to the negative pole of an interrupted circuit through a partial vacuum. The operation was accomplished with a Brilliant display of coloured lights suggesting a fireworks show in miniature. The Jar charged with Static electricity and the vacuum tube Are the foundation of the cathode photography. Faraday gave the title a a anode to the positive pole and a a cathode to the negative pole. Between Hittorff and Crookes Lis the credit of the discovery that from the cathode As Well As from Tho anode in the vacuum tube proceeds a Ray. For nearly half a Century the cathode bad been appear rays out and this suggestion professor Lenard adopted. In t he preparation of his apparatus for this important Experiment an Experiment whose Success now promises such remarkable scientific results professor Lenard sought to obtain a piece of aluminium foil j which would to free from holes but still j not too thick to permit the passage of the rays for he believed that the rays with which he was experimenting would not pass through any but a very thin piece of Metal. The foil he selected was More than i seven times the thickness of Ordinary foil but still very Light and thin. This foil i be cemented across an opening i 7-10 Mil i lira tors Wido in a Metal Cap at the end of a vacuum tube. This tiny opening with i its aluminium pane was the a windows through which the wonderful cathode Ray was to reach Tho outer world the first time in the history of modern science and probably in the worlds history that it had been released from its airless Birthplace. At the end of the vacuum tube opposite the aluminium window was introduced a brass tube within this a Glass tube of some thickness leading to an aluminium plate 12 Millimetres in diameter. This Glass tulle extended 12 Millimetres beyond the brass tube. The aluminium plate was the cathode and the brass tube the anode of the Experiment. They were connected by Platinum wires with the poles of a galvanic Battery. The whole apparatus was enclosed in a tin Box. It must have Boon with anxiety and a degree of nervous excitement that professor Lenard set his Battery in operation and started the rays from anode to cathode. The Brilliant rays from the anode were imprisoned within the tube. They could not penetrate Metal though they could pass through Glass. The cathode rays imprisoned within the Glass passed through the aluminium window and made a faint glow in the dark room mind not a glow through the dark room but in it for their penetrating Power was limited to five Cen pc meters beyond the Metal window. But they actually shone through the alumni urn through which no Ray of Light could possibly have passed. I done to know the exact Date when this Experiment was brought to its wonderful fruition hut it was some time in 1893. Not onco but hundreds of times was the Peculiar Ray made to Shine through the Metal window. Other apparatus was constructed and it was made to Shine through other metals. Its effect on phosphorescent bodies was determined and its diffusion in the air was measured. Its diversion by the use of a Magnet was a Peculiar property demonstrated. And finally professor Lenard took photographs with it on an Ordinary dry plate. What Nikola Tesla discovered. Nikola Tesla tells me he found some time ago that a when a Strong rapidly vibrating current passes through conductors there Are propagated from them certain Waves a sound Waves of electrified air a i called them. They Are propagated in straight lines like sound Waves and they penetrate bodies and they cannot Lee Stop Ped by interposing Metal of it bad Only occurred to Nikola Tesla to put a dry plate in the path of these a sound Shadow graph. From one of Roentgen s own negatives showing hand with rings on one Finger plate. If Tho cathode Waves would do this Why would not the a sound Waves of electrified air a tile Roentgen experiments with the cathode rays showed that the rays were produced in unexampled strength by the use of the Tesla converter through whose discharges the a electrified air Waves were produced. So or. Tesla very naturally tried the effect of his a sound Waves of electrified air a with Tho result of which i have told. To was the first to photograph the human brain and though he does not consider the photograph a Success he expects to improve on it. In fact he tells to he is progressing with his experiments rapidly to the Point where he Hopes to take instantaneous pictures with the new Ray. Up to this time the Best results have been obtained with exposures of an hour or More. Lenard a experiments with the cathode Ray stirred up the scientific world might by. He not Only demonstrated the possibility of bringing the new rays through metals but brought them through Glass. The Glass was thin though thinner than had been used in prior experiments. Roentgen As i have said went one step beyond Lenard. He discovered a method of intensifying the Ray so that it would pass through plates if Metal As Well As Metal foil through blocks of Wood and other thick opaque substances. This gave the discovery its practical value its value in surgery and other Fields in which efforts Aro being made to apply it now. Roentgen is entitled to nil credit for Bis development of the rays uses. But before him others deserve some credit Aud not the least among these is Nikola Tesla whose converter is the medium through which All the successful results have been obtained. The Ray has not been classified yet. Lenard believes it is eth Eric. So does Roentgen. Tesla Hopes it is a longitudinal sound wave. If it is eth Eric he says its sphere of usefulness is limited. It will probably never penetrate very great thicknesses. If it is a sound wave it can go almost anywhere through a Brick Wall or an Iron Safe. Personally conducted excursion to California.

Fierce Republic Iowa says a i have used one minute cough cure in my family and for myself with re suits so entirely satisfactory that i can hardly find words to express myself As o its Merit. I will never fail to recommend it to others on every occasion that presents Many experimenter at work. Hundreds of american scientists Are busily at work on the Lenard Roentgen discovery. They regret that Tesla or Edison did not bring the credit of it to America but they Are no less enthusiastic on that account. They have determined that some Good shall come out of America in connection with the discovery and they Are sitting up nights experimenting. If the exact nature of the Ray could be determined they could work More intelligently but they Are no worse off in this respect than Are the scientists of Germany and England. So they Are groping about hoping in most cases that they May hit on something by Accident. Edison began at the practical Side of the business As was natural. Demonstrations of new scientific facts Appeal to Edison most when he can see some Means of applying them to tim work of Man. So the first thing to which Edison turned his mind was the invention of some Means of producing the now rays without the use of the expensive Crookes tube. Tesla began to work out a moans of taking pictures instantaneously by the new photography and he Bas been engaged in trying to classify the Ray. Other scientists have devoted their attention especially to developing in the Ray the Lefrang idleness of the Ray of Light. All have repeated the spectacular experiments made abroad photographing the Bonos of the living hands Etc. It would seem now to the unscientific mind As though two things were most immediately important to concentrate the rays and increase their penetrating Power. A third result to be attained by Long and exhaustive experiments is to prove what substances Are transparent to the rays and in what degree. But the american who proves the possibility of taking a direct photograph instead of a Shadow photograph with the new rays will have his name linked with that of Lenard and Roentgen. Now All that can be accomplished with the new photography is to cast t he Shadow of an opaque substance on the sensitive plate. When Tho cathode rays Are propagated through the hand they find the flesh and blood and skin transparent but the Bones Are opaque. So the outline of Tho Bones is traced on the sensitive Plato. This has its value in surgery and already bullets and other foreign substances have been located in menus hands by the new photography. But it will reach a higher stage of usefulness when the surface of the Bone can be photographed through the flesh. Possibly before this written word sees Type that wonder too will be devel oped. Surgery moms Likely to Benefit most by the new science. It has been suggested that it can be used to detect flaws in Metal plates. Edison and others have suggested that As powerful rays of Light kill Bacilli the new Ray might be a specific in some diseases. This seems fantastic yet nothing would have seemed More fantastic to the mind of the average Man a year ago than the suggestion that his Skeleton could be photographed before he died.
