Dear M^r Talbot/

I have wished much to have had the pleasure of meeting you again at the Exhibition but I have not been so fortunate as to do so.

I hope you are satisfied with the wording of the award, but I am now writing a short report of the Jury on photography & shall be happy to combine any notes you will kindly favour me with on your processes for that purpose. ¹ – I do not wish to state what is incorrect and I gather from reading that Mungo Ponton first used the Bichromate of Potash & gelatine ² – I have also an obscure remembrance that you in conversation with me told me that used [sic] it as a portion of your new patent – It appears also to form the Base of operations for Col. Sir H^y James, ³ M^r Osborne ⁴ & others – If it is not to Mungo Ponton that the discovery is due – I should be glad to allude otherwise if it is your own. I hope you will pardon me for not being more at home on this subject & will favour me with an answer as early as you can, for the reports must be delivered as speedily as possible.

I am dear M^r Talbot Yours very respectfully & obliged
Hugh W Diamond

Pardon the old Calotype paper I write on ⁵
