[49.] Linton, 1889, p. 214. The second print mentioned is after Titian, not Veronese.
[50.] Duplessis, 1880, pp. 314-315. Duplessis, who was conservateur-adjoint in the Cabinet des Estampes of the Bibliothèque Nationale, no doubt based his judgment on the impressions in that collection. Certainly few of these were printed by either Jackson or Pasquali.
