A whole plate sheet film negative. A slightly distant starboard side view, taken from abaft the beam, of the paddle tug Middlesex (1865) at anchor in Gravesend Reach, River Thames. Five of her crew are on deck looking towards the photographer. Her boat is on a painter astern. Tilbury is in the background. This is a copy on acetate film of negative number G1680 and it has reticulated and been discarded.
