Faraday to Walter Calverley Trevelyan   5 January 1859

[Royal Institution embossed letterhead] | 5 Jany. 1859

My dear Sir Walter

I cannot suggest observations for another person nor can I reason from another persons observations - I am always obliged to observe & also think for myself. The best thing I can do is to refer Mr Tayler¹ to the Revd. Mr Farquharson² observations upon & measurements of the aurora borealis which he will find in the Phil Transactions for 1839. p.267³.

Very Truly Yours | M. Faraday

Sir W.C. Trevelyan | &c &c &c
