Faraday to Henry Enfield Roscoe   21 February 1857

21 February, 1857, | Royal Institution, | Albemarle St., W.

My dear Sir,

Last night I placed a portrait of Bunsen in the Library¹, and that led me to get a friend to read the inscription beneath; and considering the case I am persuaded that I came to a false conclusion about it. Somehow I imagined that it came from Bunsen himself, but then I do not know him personally and the inscription tells me that it is a valued personal testimony to some one in particular, and I doubt not it is you. Now I should send it back to you at once by the carrier, but am not quite sure that I have your town address, so I use this letter as a means of knowing really where you are and with many thanks for your kind intention of showing it to us here, beg your pardon for my mistake and oblige

Ever, my dear Sir, | Yours Very Truly, | M. Faraday.

- Roscoe, Esq., | &c., &c.
