74 RESPONSE IN THE LIVING AND NON-LIVING 
Tt will be seen how rapidly chloroform produces depres- 
sion of response (fig. 44), and how the effect grows with 
time. In these experiments with plants, the same 
curious shifting of the zero line is sometimes noticed as 
in nerve when subjected similarly to the action of re- 
agents. This is a point of minor importance, the

essential point to be noticed being that the responses 
are rapidly reduced. 
Effects of chloral and formalin.—I give below (figs. 
45, 46) two sets of records, one for the reagent 
chloral and the other for formalin. The reagents 
were applied in the form of a solution on the tissue at 
the two leading contacts, and the contiguous surface. 
The rhythmic fluctuation in the normal response shown 
in fig. 45 is interesting. The abrupt decline, within a
