Faraday to James Timmins Chance   11 December 1860

[Royal Institution embossed letterhead] | Tuesday 11 Decr. 1860

My dear Sir

With respect to the Small’s and my examination of it, my time is becoming very limited¹. Can you let me know when you will want me.

I could come next Thursday or Friday² (13th or 14th) but would have to return the same day.

I could come next Friday leaving London after ½ p. 3 o clk but should have to return on the Saturday[.]

I could come if necessary on Thursday the 20th (in Evening) returning on the next day[.]

After that I could not be with you before the 10th January 1861[.]

Let me know which of these it must be³[.]

I should like very much to see a lens up in your dark chamber & examine where its maximum light would fall as respects the dead horizon[.] To repeat in fact Stevensons Experiment there⁴. But now that our experiments are finished & that you have sent in your account as the TH desired I have no right to say any thing about it[.]

Ever Yours | M. Faraday
