Dear Sir

I believe you have not seen any of my photographic attempts with the Solar Microscope. I therefore enclose 4 specimens of magnified lace. ² I have great hopes of this branch of the Art proving very useful, as for instance in copying the forms of minute crystallization which are so complicated as almost to defy the pencil.

Have you tried M. Daguerre’s plan ³ yet, and with what success? I have not yet had leisure to make the attempt. The first part of his process, exposing silver to the vapour of iodine, has long been known to me, but the sensibility to light had not appeared to me sufficient. I described to Section A at Birmingham ⁴ the variable Newtonian rings which I obtained last year from this process.

I expect to be able to compete with M. Daguerre in drawing with the Solar Microscope, when a few obvious improvements have been adopted. By the way did he show you anything remarkable of this kind? ⁵

Believe me Yours very truly
H. F. Talbot
