puscles per c.c. of platinum. We may therefore say with certainty 

 that the main features of the phenomenon are to be represented 

 by a formula of the type Adh~ b/d . 



Interesting conclusions are also to be drawn from the actual 

 values of the constants themselves. From the constant A we 

 obtain the number n of free corpuscles in a cubic centimetre of 



solid platinum, since we have the relation n = | — ^- ) A

 tained by putting corresponding values 0and C in the equation
