My dear Sir,

The letter ² you forwarded to me was about your plates which I hope you have received, I gave your direction but by a blunder Giroux put my name on the package.³

You have perhaps seen the last number of the Phil. Mag. in which M^r Towson speaks of Photogenic paper which gives the light and shade in their right places.⁴ I was anxious to see these specimens. No. 1 is very good indeed.

I have examined my Camera furnished by Giroux with one of the same size & a rough lens.

The light seemed to me the same in both, but I think the lenses are so contrived that in Daguerre’s Camera the difference of focus for difference of distance is less in amount. The achromatism I [illegible] to be judge.

I have done some in the Camera on paper silvered as yet without decided success; but the weather has been very unfavorable.

Donné persists in engraving from Daguerre’s plates, though Daguerre said it was impossible.⁵ Daguerre has done a portrait of himself, said to be excellent.

I saw Cooper at the Polytechnic taking a drawing with the Oxy hydrogen Microscope ⁶.

Malaguti has made some very curious experiments upon the absorption of the chemical rays. It seems water impedes their passage less than air!⁷

Yours very faithfully
