production of the response-curves of A and B recorded 
on a fast-moving drum. It will be remembered that 
one point was touched with Na,CO, and the other with

a) Records of A and B obtained separately. R’ is the resultant by algebraical 
summation. (b) Diphasic record obtained by simultaneous stimulation of 
A and B. 
By suitably increasing the amplitude of vibration 
of the less sensitive, the two deflections were rendered 
The records of A and B were at 
first taken separately (fig. 66,a). It will be noticed that 
the maximum deflection of A was attained relatively
