Roof artificial horizon
        
        A rectangular brass-framed roof-shaped folding cover; the trough is missing. Two sides of the cover have clear glass panels, at an angle of 90 degrees. Accompanying the instrument is a cylindrical iron bottle with a threaded stopper and pouring hole. It is used for storing the mercury when the instrument is not in use. 
The artificial horizon is contained in a fitted leather carrying case which can be attached to a leather belt.
Captain Edmund Hope Verney RN (1838-1910), the original owner, saw service in the Crimea and in the Indian Mutiny.
