Faraday to James Timmins Chance   14 August 1860

Royal Institution | 14 Aug 1860

My dear Sir

Had the lamp at the North lighthouse at Whitby been adjusted before our survey of matters on the 9th instant? or was it as you left it originally and as it was when the Astronomer Royal saw it?¹ Were you with him there? and what was the judgment regarding the upper reflectors formed from observation within the lanthorn at that time?

Ever Truly Yours | M. Faraday

James Chance Esq | &c &c &c

The bundle of photographs and the drawing have been found. They came to me but I return them to Mr. Wilkins for conveyance to M. Sautter | MF

Endorsement: North Whitby | Lamp 27mm below focal plane of lenses. Same position as it had always been - not capable of adjustment - no change made. | Lamp not in center.
