[Sir Henry Ellis, Principal Secretary at the British Museum.] Autograph Letter Signed ('Henry Ellis') to the numismatist John Yonge Akerman, regarding the 'Certificate' of 'M. Meryon du Marsan' [i.e.Théophile Marion Dumersan].

1p, 12mo. In fair condition, lightly aged and worn. Folded twice. He states that the 'Certificate' of 'M. Meryon [sic] du Mersan' has been 'signed by Lord Aberdeen', and that he wishes to 'get the signatures of Mr. Gurney and Mr. Hamilton to it'. If he does not – 'or rather cannot' – send it to Akerman beforehand, he asks him if 'you can add your signature before it is read on Thursday Evening'. In addition to his literary works, Dumersan was a numismatist and Curator attached to the Cabinet des Médailles et Antiques of the Bibliothèque Royale.
