Asks permission to use information from JH's letter in Astronomische Nachrichten. Believes [Alexander von] Humboldt can explain observational anomalies that JH notes.
JH will as WT requests stop mentioning JH's hyposulfite fixing process and await publication of WT's process. Reports in detail on some of JH's experiments relating to photography and to spectrum analysis. [In a P.S. dated 1839-2-13,] JH states: 'I have discovered your secret of fixing [or its] equivalent.'
