INORGANIC RESPONSE III 
the next series of records. The wire at the low tem- 
perature of 5° C. happened to be in a sluggish condition, 
and the responses to vibrations of 45° to 90° in amplitude 
were feeble. Tepid water at 30° C. was now substituted 
for the cold water in the cell, and the responses under-

went a remarkable enhancement. But the excessive 
molecular disturbance caused by the high temperature of 
90° C. produced a great diminution of response (fig. 65). 
Diphasic variation.—It has already been said that if 
two points A and B are in the same physico-chemical 
condition, then a given stimulus will give rise to similar 
excitatory electric effects at the two points. It the
