Wishes to discuss an urgent matter.
Asks to borrow a book.
Is grateful for referring him to Capt. Ludlow. Has now moved himself to Falmouth. What does JH think of the chances of success of a popular book on photography? He is contemplating the idea. Hears that J. B. Biot considers the production of colored drawings impossible, but is not convinced himself. Encloses description and drawing of a very clever instrument.
Returns with grateful thanks the example of photographs recently sent him. They open up a new field of curious processes. Will not have much time this summer for photographic experiments as he is carrying out a series of investigations into the air of mines. Has been experimenting with the cyanurets.
