Finishing his copy of the panorama taken from the summit of Paarl rock. Needs TM's star reductions as soon as possible.
Invites TM to come see Halley's Comet in JH's large reflector. JH reports his observations of the comet.
Sends a list of additional stars to be measured for JH to use as standards.
About an anomaly in one of JH's lists of observations.
Calculates the location of the comet [Halley's].
Having read John Burrow's book, JH proposes procedure for analyzing masses of data from [African] Expedition. Will volunteer to interpolate chronometer errors if TM will undertake computations.
About the principles whereby the nomenclature of the constellations might be reformed.
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.
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.
Star within 20 seconds of the nucleus of the comet [Halley's].
Has installed his astrometer to help judge star magnitudes; also makes a comparison of barometric observations with those of TM.
Sending some equipment back and forth, and some astrometer readings.
Arranges to have tea with TM tomorrow at the Royal Observatory.
Sends observations of several more standard stars, and of the comet.
Asks TM to accompany himself and Daniel Cloetes in hunting a leopard.
Does not want to compute precessions for each individual star.
