268 Further Researches on Positive Rays [Apr. 3, 1914 



I could not discover from the pbotocrraphs any evidence of an 

 increase in the relative intensity of the molecular lines. I hope that 

 the examples I have given this evening may show that the positive 

 ray method can be applied to a great variety of problems in physics 

 and chemistry, and that its development may assist the progress of 

 these sciences.
