Autograph letter signed to J.C. Adams

Is to publish an Ephemeris of Neptune received from Encke. Has requested Lassell to make and forward observations of satellites of Neptune and Uranus, and Hartnup [Liverpool Observatory] to send good observations of Neptune. Both are also working on the diameter of Venus. JCA requested to thank Hartnup in particular as he is under appreciated by Liverpool Town Council. Emphasises the good effect a word from JCA might have in such circumstances.

Autograph letter signed to J.C. Adams

Encke has published Ephemeris of Neptune for 1853. Alas that he got there first. D'Arrest has published one for 1848-51 using some of JCA's data unattributed. Will send copies of these if JCA has not seen them.
