Le Conte engraving 
Kay’s engraving of Mr Maxwell and unidentified ladies 
The Painting
10,11] The Key-Plate suggests that the two female figures numbered 10 and 11 represent Miss Crawford of Jordanhill and her friend Miss Hay of Mont Blairy but they show no resemblance to Kay’s portraits of these two ladies. The two ladies 10 and 11 in the Key-Plate are shown in the Fig 138 of Kay’s Portraits of Mr Maxwell where they are not identified other than ‘ladies in the costume of 1785’. The Key-Plate identification therefore is incorrect. This is the only error that I have encountered in the Key-Plate.
