Scioptric ball, maker unknown, c.1745-1755, but once owned by Stephen Demainbray.

Scioptic balls were used to direct beams of light, usually the sun's rays, during optical demonstrations. This scioptic ball once belonged to Stephen Demainbray who used it in his lectures on natural philosophy. Demainbray worked as superintendent at the King's observatory at Kew from 1768 and his collection of instruments and apparatus was absorbed into the King's own collection.
