This diagram of a square and circle may have been used in Turner’s later lectures on geometry, given as Professor of Perspective at the Royal Academy.
Peter Bower (unpublished notes)1 writes that the sheet is Double Elephant size Whatman paper made by William Balston and Finch and Thomas Robert Hollingworth, at Turkey Mill, Maidstone, Kent. Bower notes that ‘all of the group of papers with 1794 dates in the watermark show considerable process dirt and poor formation. Perhaps this lack of quality control at Turkey Mill was the result of the disruption caused by James Whatman’s stroke and the change of ownership at the mill’.
