INORGANIC RESPONSE IO! 
(2) The cell is usually filled with tap-water, and 
a period of rest after making up, generally speaking, 
improves the sensitiveness. These expedients are 
ordinarily sufficient, but it occasionally happens that 
the wire has got into an abnormal condition. 
In this case it will be found helpful (3) to have 
recourse to the process of annealing. For if re- 
sponse be a molecular phenomenon, then anything that 
increases molecular mobility will also increase its

intensity. Hence we may expect annealing to enhance 
responsiveness. This inference will be seen verified in 
the record given in fig. 58. In the case under con- 
sideration, the convenient method employed was by 
pouring hot water into the cell, and allowing it to stand 
and cool slowly. The first three pairs of responses 
were taken by stimulating A and B alternately, on 
mounting in the cell, which was filled with water. 
Hot water was then substituted, and the cell was
