Faraday to Josiah Latimer Clark   5 March 1860

[Royal Institution embossed letterhead] | 5 March 1860

My dear Sir

My subject next Friday is the lighthouse¹[.] I am sorry that I have not power to offer you a ticket either to use or burn but I am asking Members for a ticket if they have one to spare.

The experiment you describe is a very interesting one & I thank you heartily for you kind offer which however I cannot avail myself of this time as my subject is far away from it. I think I heard Mr. Barlow speak as if he hoped that you will or would tell us some of your stores of knowledge² & that gives me some hopes that you will describe & shew the experiment here.

Ever My dear Sir | Truly Yours | M. Faraday

Latimer Clarke Esq | &c &c &c
