'Procured a couple of curious silver medals, one of the Pretender VNICA SALVS, the other of his two sons, at Shurman the Braziers in Holborn, before I went to fencing,for the Duke of Devonshire. Sent them to the Duke after breakfast, just as he was setting off in his Post chaise for Derbyshire.' (Burnett 2020b, p. 1644)
