Sends observations of several more standard stars, and of the comet.
Sends observations of several more standard stars, and of the comet.
Sends formulae for dealing with the apparent differences, in viewing the comet and compared star, due to the effects of parallax and refraction.
Calms TM about not having his comet observations published yet; those published so far are not of much value.
A note along with a request from Niccolo Cacciatore for some observations that JH says he cannot make.
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.
Finishing his copy of the panorama taken from the summit of Paarl rock. Needs TM's star reductions as soon as possible.
Thanks TM for the right ascension reductions. Saw the comet [Halley's] last night, but it was dimmer than before.
Asks for TM's barometer and thermometer readings for 20-28 September.
Uncertain when they are traveling to Paarl.
Invites TM to come see Halley's Comet in JH's large reflector. JH reports his observations of the comet.
Calculates the location of the comet [Halley's].
Comments concerning Francis Baily's book on John Flamsteed.
Calculates the location of [Halley's] comet.
Star within 20 seconds of the nucleus of the comet [Halley's].
Arranges to have tea with TM tomorrow at the Royal Observatory.
Asks TM to accompany himself and Daniel Cloetes in hunting a leopard.
Does not want to compute precessions for each individual star.
Notes a discrepancy in TM's latest observations and those of Thomas Brisbane.
Congratulates TM on the birth of his son, George.
Inquires about a star not found in TM's list of comet stars. Believes that their comet collaboration is going well.
