Faraday to Richard Hayton Davis 4 June 1864

[Royal Institution embossed letterhead] | 4 June 1864

My dear Sir

I thank you for your hearty invitation during the summer¹. I do not think that I shall be able to accept your kindness though it might do me good & would be very pleasant but I must leave the future to develope its own history. In the mean time I thank you very much[.]
