Thanks JH for explanation of phenomena [see HS's 1849-12-4]. B. A. Gould [?] has begun to publish American version of Astronomische Nachrichten, but without strong financial backing.

Wilhelm Struve stayed several days with HS enroute from England to Pulkowa, but forgot to leave copies of [JH's Cape Results] for HS and K. L. C. Rümker. Later, Struve forgot to give these to G. B. Airy, who was visiting Pulkovo, for delivery to HS. HS has not yet seen Cape Results, or J. J. Lalande's catalogue to be sent by B.A.A.S. Happy to publish R.A.S. invitation for observations of solar spots. Short poem about Rümker losing a comet.

Discusses a letter in which JH explains why JH cannot, as a British subject, accept the foreign order offered him [by the Danish king]. Asks HS to read over the letter and to decide how it should be delivered.

JH replies (to RS:HS 15.389) that neither JH nor his father held that the moon influenced the atmosphere, though JH does connect a full moon with a clear sky. [Eliza] Hamilton, sister of W. R. Hamilton, has published some poetry that is not well known, but deserving. Cannot accept foreign order.
