Has replied to Richard Sheepshanks in the Memoirs of the Astronomical Society. Is surprised how near he got to the general figure described by the Circle Centre. Comments on calculations he intends to carry out. Cannot say decidedly that Zeta Octantes is double; it is doubtful seen through the 8-ft. transit.

Summary:

Sends C. P. Smyth with the observing lists of JH's zero stars. Comments on these lists. Would like to see the Cedar Mountains, but cannot spare the time at present. Wished to visit Riebeck's Castle to verify one of N. L. Lacaille's remarks. Did not notice any air bubbles in JH's barometer. The Observatory barometer is similar to the one of Sir John Franklin. Goes to the Block House tomorrow to commence the triangulation.
