Correction to JH's paper on double stars [see JH's 1849-3-26 & 1849-3-25].
Thanks JH for Cape Results sent through [F. G. W.] Struve. Further grateful for the N. L. Lacaille and Jérôme Lalande works sent to the observatory. Appreciates reduction of the moon results as well as the magnetic observation of 1845. Reveals new development in double star zones[?]. Comments on making magnetic observations.
