[Royal Institution embossed letterhead] | Albemarle St W. | 28 Novr. 1859

My dear Sir

I thank you heartily for your notice. The auroral period which it refers to was wonderful & I do not at all doubt the fact. I was at that time in Scotland & the phenomena were wonderful. The auroral influence must have been simultaneous for the whole earth¹[.]

Ever Truly Yours | M. Faraday

Robt. Mallet Esqr | &c &c &c
