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 Ad*e~ bl0 . 
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 is ob- 
tained by putting corresponding values 6 and C in the equation
