Dimensions of Physical Quantities. 113 



electromagnetic quantities as being of the same absolute 

 dimensions. 



I therefore give a Table in which the powers in which K 

 and /i enter into the various electrical and magnetic quantities 

 are shown. 



If we put K = l we get the ordinary electrostatic, if /i = l 

 the ordinary electromagnetic dimensions.
