William Wyon to Faraday   29 April 1839

Her Majestys Mint | 29 April 1839.

My dear Faraday,

I think you said the days that would suit your convenience best would be Mondays & Thursdays - allow me to name Thursday¹ & at any time agreeable to you - I have asked my friend² who cast my own face to make one of you for me & he has promised to call on you at the Royal Institution but I will thank you to let me know the hour & I am sure he will be punctual. This operation will not take more than half an hour & will save you much time eventually - & Pray tell Mrs. Faraday that I will be answerable for your not suffering much inconvenience[.]

Ever Yours | W. Wyon

Address: M. Faraday Esq | &c &c &c | Royal Institution | Albemarle St,
