Excerpt from Electric Light, Its Production and Use: Embodying Plain Directions for the Working of Galvanic Batteries, Electric Lamps, and Dynamo-Electric Machines
With regard to this, Professor Daniel, whose elegant and careful writing is still worth quoting at the present day, remarks - The disruptive discharge of the voltaic battery through air is de pendent upon precisely the same principles as that of the Leyden battery; but the phenomena are modified by the lower intensity, greater quantity, and perpetual renewal of the force. When passing between two charcoal points, its duration renders it the most splendid source of light which is under the command of art. When the poles of a powerful battery are gradually separated after contact, the discharge takes place through an interval which increases with the heating of the air by the ignited charcoal. With the original battery of the Royal Institution of plates, the discharge passed through four inches of air; and with the constant battery of 70 cells the flame is much more volumi nous, and extends to the distance of one inch.
