TEE PHYSICAL LABORATORY * 117 



at the University of Manchester, England. Time will not permit me to 

 go on with the history of this fascinating subject, but I will only remark 

 that in all the great countries radiological institutes have been founded 

 for the purpose of carrying on researches on the medical applications 

 alone of radioactivity, so that here again we may expect great practical 

 results. 



I hope I have now sufficiently shown the nature of the contributions 

 of the physical laboratory to civilization, not only in the practical mat- 

 ters of making life easier and more agreeable, but also in the extension 

 of our intellectual outlook, and the making of life more worth living.
