THO-RAD-X. 

 A Substitute for Radium, 



What may possibly become an important factor in medical and 

 chemical science is a new discovery, or perhaps what you might call a 

 preparation, called Tho-Rad-X, which is the product of research by 

 Drs. Bailey and Blackman, of Chicago. 



Tho-Rad-X is a saffron kind of rock, and is claimed by its inventors 

 to be even more powerful than Radium, and at the same time very 

 much cheaper to produce. 



Dr. Bailey, of the Hahnemann Medical College, says it is produced 

 from a rock found by a member of the Chicago Board of Trade; the 

 rock is pitch-blende, and has been assayed as such by Prof. W. F. 

 Hildebrandt, of the Smithsonian Institute. 



The rock contains, among other things, Radium, Uranium and 



CT5 Thorium. This substance contains the ultra violet or purple ray to an 



'^^ unusual degree, and is not diminished by time.
