Adam Volumes 11/4 and 11/5 are incorrectly inscribed by William Adam (1738-1822) as being for Admiral Boscawen, presumably for his house at Hatchlands. This is not possible, however, as we can see from the scale bars that this ceiling design was intended to have dimensions of 30 x 30 feet, and there was never a room at Hatchlands large enough to accommodate it.

This design was not executed at Shardeloes either, but it is drawn in the early Adam style, dating it to the same period, and has been attributed as an alternative design for the ceiling of the hall (later saloon) on the grounds of the dimensions which match the room in question.
