Note 66 — APPENDIX.
Reading edition
The word statical has been used to designate phenomena which are the effects of electricity when at rest, as when accumulated upon conductors or the surfaces of panes or jars. Phenomena which are supposed to arise from electricity in motion (forming a current) are designated as dynamic. Thus, when charging one side of a pane produces the opposite state in the other, the effect upon the latter is ascribed to statical induction; but when a discharge of electricity through one wire, causes a current in another, forming an adjacent circuit, the result is ascribed to dynamic induction. This method of designation is employed whether the alleged current be owing to electricity generated by friction, as in the case of a machine, or generated by chemical reaction, as in the case of a galvanic battery. A good word is wanting to distinguish electricity, when produced by friction, from electricity produced by galvano-chemical reaction: for want of a better, I will resort to that employed by Noad, (frictional,) which has the advantage of being self-explanatory.
