Faraday to Martin Farquhar Tupper¹   3 July 1862

[Royal Institution embossed letterhead] | 3 July 1862

My dear Sir

I am very much obliged by your kindness in sending me the photographic copies of your medals. I guess as well as I can whether the metal of each was gold or silver[.]

Ever Truly Yours | M. Faraday
