Octant
An octant is a navigational instrument used for measuring angles necessary for determining a ship's position at sea. This example dates from around 1820. It was retailed by Alexander Cameron, a jeweller and nautical instrument retailer based in Dundee.
The octant has an ebony frame, brass fitments and an ivory arc. The scale-dividers mark is indistinct. Engraved on the index arm is 'Cameron, Dundee'.
Alexander Cameron had premises in Dundee's High Street from 1818 to 1824, and at 120 Overgate from 1828 until his retirement in 1848.
