 of which indicates that the needle which 

 has pursued its travels in so many persons, 

 through so many years, will be suppressed by 

 the camera. 



"My next object is to photograph the bones 

 of the entire leg," continued Herr Spies. "I 

 anticipate no difficulty, though it requires some 

 thought in manipulation." 



It will be seen that the Rontgen rays and their 

 marvellous practical possibilities are still in their 

 infancy. The first successful modification of the 

 action of the rays so that the varying densities of 

 bodily organs will enable them to be photo- 

 graphed will bring all such morbid growths as tu- 

 mours and cancers into the photographic field, to 

 say nothing of vital organs which may be ab- 

 normally developed or degenerate. How much 

 this means to medical and surgical practice it re- 

 quires little imagination to conceive. Diagnosis, 

 long a painfully uncertain science, has received an 

 unexpected and wonderful assistant; and how 

 greatly the world will benefit thereby, how much 

 pain will be saved, only the future can determine. 

 In science a new door has been opened where none 

 was known to exist, and a side-light on phe- 

 nomena has appeared, of which the results may 

 prove as penetrating and astonishing as the 

 Rontgen rays themselves. The most agreeable 

 feature of the discovery is the opportunity it 

 gives for other hands to help; and the work of 

 these hands will add many new words to the
