[R] In the response of inorganic matter I have obtained records of positive, diphasic and negative responses. It would perhaps be advisable to refer the ‘A’ and ‘D’ effects, to physico-chemical change. The simultaneous double reaction, combination and decomposition, is of frequent occurrence in many chemical changes.
