Description

Experiment showing glow effects and dark intervals within glass tubes filled with mercury vapour. Sparks between the negative electrode formed of a tube of aluminium foil and the positive electrode of long aluminium wire running parallel to this.

Text accompanying this image states that the circular area of darkness was created by an electromagnet: ‘If in the vessel (fig.1) a small electromagnet is introduced into the inner cylinder with its axis at right angles to the axis of the cylinder, it is found that the parts of the aluminium foil covering the two poles of the magnet are absolutely dark (fig. 8…)’

Additional print of figure 8, plate 4, from the manuscript version of the paper ‘Experiments on the discharge of electricity through gases. Sketch of a theory’, by Arthur Schuster, Proceedings of the Royal Society, vol.37 (1884), pp.317-339. The published version appeared as the Bakerian Lecture for 1884.

Inscribed in ink: ‘2’; and verso ‘Schuster’.
