Paget type, artificial bubble horizon, designed and made by Henry Hughes and Son, City of London, England, 1905-1910. Mounted behind the horizon glass of a sextant it consists of a curved bubble level in right-angle tube containing a prismatic lens with cross-wires and adjusting screws. In use the observer views the bubble via the prism and aligns the cross-wires, which replaces the horizon. It can only be used during daytime with sufficient light, an improved version, from around 1914, was fitted with electric illumination for night-use.
