This sheet of notations includes three enclosures, the first, described as 'Position of the verticals for notation 84', appears to be a completed additional notation, dated 16 April 1838 and was numbered F.84 by Bromley. Dimensions 64 cm x 48 cm.
The second and third enclosures are untitled but contain manuscript notes and diagrams relating to the barrels and stores. These enclosures, numbered F.84 and F.84 respectively by Bromley, are also undated, but a date of 1838 April can be inferred from the date of the notations. Dimensions 29 cm x 44 cm, and 30 cm x 43 cm.
