William Wyon to Faraday   1 May 1839

Her Majestys Mint | 1st May 1839.

My dear Faraday,

I have seen my friend Mr Rouw¹ who has promised to be with you tomorrow Thursday, at 3 oClock.

I am almost afraid that I shall be unable to be with you but luckily my services are not required on this occasion[.]

Ever believe me to be | Yours truly | W. Wyon
