168 CATHODE RAYb. 



stood by itself we miglit think that it was probable that e was greater 

 than the atomic charge of atom rather thau that m was less than the 

 mass of a hydrogen atom. Taken, however, in conjunction with 

 Lenard's results for the absorption of the cathode rays, these numbers 

 seem to favor the hypothesis that the carriers of the charges are 

 smaller than the atoms of hydrogen. 



It is interesting to notice the value of e/m, which we have found 

 from the cathode rays, is of the same order as the value of 10-" deduced 

 by Zeeman from his experiments on the effect of a magnetic field on 

 the period of the sodium light.
