"An electrized rod, brought towards the cap of the instrument, causes the leaves to diverge or repel each other. It is not necessary to touch the cap of the electroscope with the electrized bodies, in order to pass into or on the rod connected with the leaves the electricity we wish to examine. By an influence called "induction," to be more fully explained hereafter, the leaves are found to posses the same kind of electricity as that enjoyed by the electrized body." - from "Cyclopaedic Science Simplified" 1889 (J.B. Lippincott Company) [republished in 1988: Static Electricity with 30 Experiments - by J.H. Pepper]
