Name: Engraving depicting Davy's experiment with a mercury vapour light. A long u-tube contains two columns of mercury: both ends of the tube are immersed in cups of mercury. When an electric current is passed through, the air between the columns glows with a feeble bluish light. Heating intensified the light, and the introduction of air bubbles changed it to purple. Davy concluded that the light was due to glowing mercury vapour. - SuperStock
