Has been to see [Richard] Jones, who has undergone some 'abominable' treatment; Mrs. Jones believes Jones is recovering; JH talks about a plague of boils in England. JH comments on the activities of a little kitten, on Annibale de Gasparis having found another planet [Eunomia?], and on a strange poem being written about the Crystal Palace by a man named [?] Warren.

Most of the letter is taken up in replying to MH's letters; JH talks about Charles Wheatstone's idea of 'binocular Daguerreotypes,' and about a chart of all balloon ascents, prepared in Paris, and brought to JH by a friend coming from there.
