SEES HIS OWN BRAIN
.DR. CARLETON SIMON OBTAINS RE
 MARkABLE PICTURES.

seen-Tsls Hypnotic Power.
 Inc Erlnan brain has been photo graphed. In tho rivalry of scientists ex cited by Roentgen's application of the cathode 4 rays to photography Dr. Carle- ton simon steps forward and exhibits picture of his cwn brain, obtained from process in which the cathode ray IS not factor. It may be said, how ever. that the widespread interest att tracted to Roentgen 8 discovery and the experiments of Edison preparatory to his attempt to photograph the brain. as chronieled from day to day, were the incentives that led Dr. Simon, after nearly three years of labor, to bring to bear his whole power on a final attempt to capture tho prize of honor in being tho first to photograph the brain of q living being.
 Dr. simon, who is graduate of the Now York university, a pupil of Char cot of Paris, and member of the New York polyclinic, thus tells the story of his efforts to photograph tho brain and his eventual success:
 '.The brain, you know, has been my especial study, and have worked inde- pendently in quiet way for nearly three years to photograph it. first sought to accomplish my purpose by passing q continuous current of cleo tl1city through the brain, Illuminating it by the spark, and then 1 tried the in- terrupted current, but this produced a paralysis of tho brain, rendering sense- less tho subjects. The principle is illus. trated by flash of lightning on dark [ night, which carries images through which 1t travels to the eye From this indeed 1t was suggested to me that the same idea might be applied to the brain. Again, you know, the flrefy is mado almost transparent by its tiny lantern.
 Now, finding that flashes of cleo tricity passing through the body form circuit at tho smallest possible points, found that instead of passing directly through the brain it travelled through the skin around the head, and if, on the other hand, the flash was drawn through the brain by magnetic attrac- tion, paralysis took place
 1T then attempted to use the alternat- ing, interrupted current, but found that insulation of the skin was impossible. I tried to follow nature, as in the fire fly, in the production of transiridescent rays. After great deal of labor suc- ceeded i'll equalizing to considerable degree the average between the rapidity with which light travels and the rapid ity with which sound travels. It has seemed to me in my experiments that whenever the rays of light trayeled slowly or nearer to the rate at which sound travels this same light would ill some unexplainable manner appear to ps combine with waves of sound.
 "I am still far from having perfected the instrument by which am able to photograph the brain. Of eourse the moro solid structures are reflected on the plates, and found that the less ex- posture l gave to tho photographic plate the easier l apparently was able to photograph translucent material.
 .'The rays 1 use, 1 use in conjunction with sound, and they are electric rays, so far as tho light is concerned. 1 have attempted i'll this instance to photo graph my own brain, not being able to procure any ono whom 1 thought would be appropriate.
 Dr. Simon said that he used an ordi- nary camera, with platinum plates, # subjected neither to heat nor to any < especial chemical treatment The time # of exposure was limited to two minutes. @ Ordinarily, tho doctor said, the timo of d exposure would be regulated by the depth of material through which the # light must pass.
 M For the, present Dr. Simon will not make known the details of his appa- N ratus "I do not like he said, "to # withhold it from the public, but l de- slre to moro fully perfect it before mak-
 Ing the details known.
 # He pleaded guilty to the suggestion
 vat 1t would be source of satisfaction G accomplish himself the perfeeting of the process which he has discovered
 This much he did say:
 U prodnce the effect by traction of the light and propulsion through the
 brain substance. At the time of photo graphing tho whole internal chamber
 of th9 brain is lighted up.
