The almost 250-year-old diary of a ship's captain unearthed in a dusty old box at a home in Glenfield has been sold for £4,900.
The box had been destined for the skip when the owner realised the diary, charting a journey by the East Indies Company ship Bridgewater from London to China via India, might have some value.
It went under the hammer at Hansons Auctioneers in Derbyshire last week with a guide price of £300 to £500.
But it raised much more than that. However, the identity of the new owner has not been revealed.
The log is by a Captain Skottowe and contains insights about life on the seas, what the crew ate, how they were punished and various illnesses and accidents that struck the ship.
Auctioneer Charles Hanson said: "The book is incredibly special since it records the life and times on board the ship Bridgewater, which set sail from London in 1769 to Madeira, Madras and China."
