Comments concerning Francis Baily's book on John Flamsteed.

Thanks TM for the right ascension reductions. Saw the comet [Halley's] last night, but it was dimmer than before.

Problems observing Halley's Comet. Sends first batch of TM's reduction of Thomas Brisbane's stars. Does JH approve J. C. Adamson's and J. R. Innes's offer to help calculate and tabulate Expedition data? Francis Baily's proposal to rename constellations. Renegotiating price for repairs on equatorial. Describes dream resulting from reading Baily's life of John Flamsteed.

Has compared TM's observational measurements with those of the Brisbane catalogue, and finds TM's observations to be better; is working on a star photometer.

JH's observations of the comet [Halley's], together with comments on constellation nomenclature and stellar magnitudes.

Calculates the location of [Halley's] comet.

Observation of Halley's Comet. Sends servant to pick up information on star 'Constants.'

Star within 20 seconds of the nucleus of the comet [Halley's].

Encloses the list in JH's own handwriting. Has placed two silver wires in the eye piece of the micrometer. Will JH secure him some cobweb for placing in the micrometer.

Sends the original of the barometer observations as he cannot spare the time to copy them. Had hoped to have the Brisbane stars ready on Monday. Comet was invisible last night.

Has installed his astrometer to help judge star magnitudes; also makes a comparison of barometric observations with those of TM.

Dr. Andrew Smith called yesterday. Has succeeded in establishing a postal system for the Observatory. The comet was faint last evening. Had a parcel from the Admiralty but no word about the tide gauge. Sends the Simon's Bay observations, also the P. P. Barraud chronometer, which loses time at a great rate.

Sending some equipment back and forth, and some astrometer readings.
