RADIANT ENERGY 417 



The work of Gurwitsch and his collaborators may prove to be 

 erroneous. Misleading factors may be involved of which all the 

 experimenters are ignorant. If it should be necessary later to 

 make substantial modifications of the discovery of Gurwitsch, 

 we shall yet be forced to grant that the giving off of a form of 

 radiant energy by protoplasm is not merely a possible but a very 

 probable event.
