A Naval Sextant, of Ebony, Brass and Ivory, by Spencer, Browning & Co., London, circa 1850.

A sextant is an instrument used to measure the angle between any two visible objects. Its primary use is to determine the angle between a celestial object and the horizon. Knowing this angle, together with the time at which it was measured, enables the user to calculate a position on a nautical chart

This beautifully made example belonged to Lt. Edward Cecil R.N. (1834-1862), son of the 2nd Marquess of Exeter (1795-1867), who briefly commanded the gunboat Dapper, which was part of the Baltic Fleet in the Crimean War.
