SGINTILLOSGOPE 



(Patent) 



t HOWS a mag^nificent display of scintillations, 

 showers uf spatks, direct from the mineral 

 Pitchblende, Radium, Polonium, Uranium, Thorium, 

 or any radio-active substance, even an Incandescent 

 tias Mantle contains sufficient Thorium to excite the 

 very sensitive screen iji the Scintilloscope, which is far 

 more sensitive than the Spinthariscope. The ScinLilloscope rivals the 

 most delicate Electroscope as a detector of Alpha rays. 



The eye sees an inexhaustible shower of stars of white Hght, givin.^ a very 

 realistic idea of the ceaseless activity of these marvellous substances which are 

 producing the terrific bombardment causing this beautiful display.

 and Pitchblende Screens, giving brilliant effects, Complete, 7.s. 6d., Post free, U.K.
