TALBOT8019

Dear Mr Talbot,

I thank you very much for the kind offer of your Phosphoroscope. ¹ I would have accepted of your offer with great pleasure at any other time, but I am at present occupied with preparing for publication an account of some old experiments ² which I had expected to extend, but which I can now only revise.

I expect to be at Allerly ³ on Thursday the 23^rd, where I shall look at your paper on Spectral Analysis. ⁴ Are you satisfied with Kirchhoff’s account of these in the last N^o of the Phil. Magazine. ⁵ I shall be at 7 Greenhill Gardens ⁶ till the 23^d and would wish an answer to the above question.

I am Ever Most Truly yours
