Dear Sir

I am very much obliged to you for a sight of your photogenic drawings, some of which possess great beauty, and give promise of still more. I have found out how to use the ferrocyanate, ² viz. by washing the picture with it, & then washing out, 3 times successively–

If there is a meeting of the R. Soc^y tomorrow, I intend to request M^r Christie to read a note, ³ briefly mentioning the nature of my processes; ⁴ which will then be free to all the world to adopt, or to find out better ones for themselves.

The weather both yesterday and today was of the most Antiphotogenic description, in London.

Believe me Yours very truly
H. F. Talbot

P.S. I hope you received my letter of yesterday
