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.

Stratford, William Samuel (? 1791-1853) naval officer and astronomer
