WONDERFUL NEW APPLICATION OF
 RoENTGENs x RAYS.

May Be Directly Observed.
 Edward P Thompson, consulting electrical engineer of Beekman street New York, who has been experimenting with Professor Roentgen's discovery made the statement the other day that he had discovered process whereby motion otherwise Invisible micht he observed with the use of the new x rays. Mr Thompson says that by his nrocess the movements of a watch can ba observed through tho case and tbe operation of the interior organs of n living human being or animal he made visible.
 MT. Thompson has not yet been able to make complete experiments and has noa secured results that conelusivelv demonstrate the practicability of the discovery he claims to have made. He has submitted his process to several ex nprts, including Professor Pupin of Columbia college and Thomas A. Edi son. and says they fully agree that it is entirely feasible. He is to continue his apartments in Edison's laboratory and expects soon to show absolute results. Mr. Thompson claims that the sim plicity of his discovery will make it's feasibility easily apparent to those ao- ouainted with the new process.
 The value Of such a discovery to the science of surgery and medicine can well I he imagined from the claim of the in- E yentor that with it the action of the E heart and the digestion of food can be observed Mr. Thompson says that his E discovery may be identical with that of Professor Salyioni of Perugia, who read E aaper before the Rome Medical aead- emy few days ago on process which enabled the human eye, by means of the Roentgen rays, to see through anything the rays can penetrate. Professor Sal yioni, however, did not disclose his | uocess, while Mir. Thompson, who has Il already had the priority of his discovery ' attested says Eo is quite willing that E the world should know all about his E process.
 ' In the process as carried out by E ROentgen, the effect of the cathode rays after passing through opaque objects
 must be developed by photography, and. therefore, great deal Of time is oceu.
 pied between the exposure and the ob-
 aining of the picture, said MT. Thomp-
 SOL By my process 1t is intended that objects ordinarily invisible may be ex- amned instantly, and especially that H motion may be represented 10 the eye. E For example. if q purse containing coins | be shaken, the movement of the coins ! relatively to each other will be apparent, and also the motion of the purse as a whole. Again, with powerful rays. it I ought to be possible with this process to see the motion of the muscles and the joints. when ones finger is bent or to | bs able to distinguish sprain from a # hlak by moving the arm back aud forth X Gtos see the circulation of the blood. E. he beating of the heart. and the motion H sap in trees and plants, and of all ether objects which at present cannot be ' observed.
 H The process consists of three steps first, n generating cathode rays, pref | aably with an aluminium tube, to per
 nit the easy exit of the rays; second, in
 receiving the rays upon substance
 which will change the refrangibility of
 the rays aud convert them into visible
 rays, and, third, tho interception of the
 rays, more or less, by q nonhomogeneous
 object, whereby the fuorescent material,
 such as canary glass, will be differently
 illuminated according to the strength of
 nefays after passing through the said
 ODleeI The finorescent materials are
 uahlum or canary glass, barinm plati-
 eyanlde, barium manganic cyanide,
 "cnSihe and other fiuorescing materials. II It IS desired to obtain picture

 MOntlum or calcium chloride, or other
