Wind is likely to be higher in the evening. Would like JH's views on the effect that the motion of the center of the mural circle has on the readings of the microscopes. Wind was too high last night to observe Zeta Octantes.

Summary:

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.
