Forwards a request from C. F. Gauss for magnetic observations made in England.
Compares magnitudes for some specific stars and then comments more generally on that question; JH believes he will no longer be able to observe in winter in England as he is too severely afflicted by rheumatism.
Sends HS's observations of magnetic declination and dip near London for forwarding to Carl F. Gauss. Encloses a letter from Edward Sabine.
Asks permission to use information from JH's letter in Astronomische Nachrichten. Believes [Alexander von] Humboldt can explain observational anomalies that JH notes.
