To night I shall try and explain to you in brief form the different phenomena which take place, and the reasons why they take place, when a signal of any kind is transmitted from one spot to another without the means of ordinary wires.

I shall commence by explaining very briefly a few fundamental facts, without the knowledge of which it will be hard to understand later phenomena.

First of all a few Laboratory experiments may not be out of place; if we rub briskly a stick of sealing wax with a dry flannel we shall find that it acquires the property of attracting light bodies, and of giving feeble sparks if the knuckle be presented to it. And if a stick of glass is similarly rubbed with a piece of silk, a charge, so to speak, is produced in it, like in the wax. Now it will be noticed that if these two charge-contained sticks are placed near one end of a magnetic needle, that end will always move
