Artificial Mercurial Horizon
A rectangular mahogany trough and a mahogany-framed roof-shaped cover. Two sides of the cover have clear glass panels, at an angle of 90 degrees. Accompanying the instrument is an empty circular wooden jar with a threaded stopper and a bone or ivory spout. It is used for storing the mercury when the instrument is not in use.
The artificial horizon is contained in a fitted mahogany box, with a trade label in the lid for Charles Wilson, late J.W. Norie and Wilson, 157 Leadenhall Street, London.
