FIG. 18. Curve obtained when 
the values of Z given by the 
application of the formula 
Z = fj- - K\ I to the experi- 
ments performed with a primary 
voltage of 2 are plotted against 
the values of K used in these ex- 
periments. Abscissae represent 
values of K; ordinates represent 
values of Z. The equation for 
this curve is K = 18 Z.

an equation which enables 
us to determine the value 
of make stimuli at any 
given primary voltage, for 
which the value of a is 
known. 
There remains now for 
the completion of the make 
shock formula only the 
establishment of a definite 
relationship between the 
values of a at various 
primary voltages and the 
voltages themselves. To 
determine whether such a 
relationship exists another 
curve was plotted, prim- 
ary voltages against values 
of a previously determined. 
This curve is represented 
in Fig. 19. It has the
