Faraday to James Timmins Chance   1 October 1860

[Royal Institution embossed letterhead] | Albemarle St. | 1 Octr. 1860

My dear Sir

Where you are I don’t know or whether you had my letter¹ about rotating the S. light apparatus: but I dare say you have received it. The piece of reflecting prism which you sent me was left at the Whitby light but can you let me have on the part of the Trinity house two such pieces corresponding to near the top & the bottom of the upper set of reflectors² that I may practically consider the best method of observing a distant object in them? Shall we be able to rotate the S Light?

Ever Yours Truly | M. Faraday
