[Phys-l] Am I missing something here?

[Bernard Cleyet <bernardcleyet@redshift.com>]

"In 1898 Wien studied the canal rays discovered by Goldstein and  
concluded that they were the positive equivalent of the negatively- 
charged cathode rays. He measured their deviation by magnetic and  
electric fields and concluded that they are composed of positively- 
charged particles never heavier than electrons."
