Excerpt from Electro-Medical Instruments and Their Management, and Illustrated Price List of Electro-Medical Apparatus It is of the greatest importance and convenience that there are bodies which conduct, and others which do not conduct electricity, for we are thus enabled to direct the electricity exactly to the spot where we desire its action, and to send it along metal wires which are supported by insulators, over any distance we like. By rubbing a glass stick, we have separated the positive and the negative electricity contained in the stick: the positive electricity remained in the glass bar; the negative passed through the rubbing cloth and the body of the rubbing person into the earth. In rubbing a metal stick we separate the two kinds of electricity in the same way; but we can prove this only by insulating one end of the metal stick, for instance, . By cementing it into a glass tube, and holding the glass tube in our hand while rubbing the metal. If we were to touch the non-insulated metal stick, the separated negative and positive electricity would get te united again immediately through the body of the rubbing person, and would leave no trace at all.
