Explains in detail his photographic method for producing landscapes on paper.
Describes a method developed by [J. J.] Heilmann of 'taking from glass negatives positive impressions of different dimensions.' Praises JH's suggestion that public records be preserved on microscopic negatives.
Is willing to be a witness to some battery experiments by J. P. Gassiot, but JH is busy, mostly with house hunting, and so may not be available.
Agrees to provide Josiah Quincy with extracts from letters by James Grahame. Highlights of Grahame's life.
