“DOTTING” APPARATUS. 
McDougall’s Pattern for determining individual 
differences in “ Motor Fatigue.” 
This is housed in a polished mahogany desk-like 
box with top 17" x llj". The specially printed paper 
passes under an adjustable opening at A, there being 
a sliding shutter which reduces the opening from 2V 
to 1|". The spring motor is of the gramophone type 
with the winding handle at H. The starting lever is 
seen at 5, with the regulator immediately underneath ; 
this enables the speed at which the paper passes the 
opening to be varied.
