John, 7th Earl and Duke of Rothes.
6 x 7ins.
Inscribed as ‘from the original of Sir P. Lely in the collection of the Earl of Rothes. Drawn by W. Hilton R.A. & Engraved with permission by C. Peart.’
The portrait by Sir P. Lely of the Earl is unlike this illustration which was almost certainly taken from the Wright portrait (q.v. P5.)

Detail 4 x 3ins. from the same portrait
