Is very thankful for the meteorological observations sent to JH, and makes some suggestions for additional and continued observations.
Is very thankful for the meteorological observations sent to JH, and makes some suggestions for additional and continued observations.
Note of thanks to JH for interceding on AS's behalf.
JH and his family went on an excursion and collected plants. JH is now sending some that survived well and asking WH to identify them.
Is sending WH a plant sent earlier, but this one has a bulb attached.
Introduces [Charles?] Cameron. Received angry and excited letter from Charles Babbage. Discusses barometers. Heard Herschels may be travelling to Rio de Janeiro.
Reports the death of family members. Reveals news of new Pulkowa observatory. Has completed his work on micrometer measurements, resulting in 10,500 observations. Includes lists of aspects of his works.
Wonders if JH has received AQ's letters and works sent to the Cape. Sends more. Has been doing meteorological observations. Will send some if JH wishes. Mural circle and transit instrument finally in place. Problems with equatorial; therefore missed Halley's Comet.
Pleased to hear JH's work is progressing. Disappointed with Dr. [John] Davy's meteorological observations at Malta. Comments on other scientific news, including recent eclipse, [Andrew] Crosse's controversial artificial crystals at Bristol B.A.A.S. meeting, JF's 1832 observations in Switzerland, and William Whewell's and William Buckland's books.
Discusses methods of magnetic observation, JH's actinometric readings in the Cape, and the need for more physical observatories.
Replies to WH's letter on 'Scotodynamics.' Cannot follow WH's analysis of velocities of vibrations and disturbances, but finds it symbolically beautiful and powerful. Notes that diploma [?] arrived and was sent to Hanover. Thanks WH on behalf of Caroline Herschel, who sent a letter acknowledging the honor bestowed on her by Royal Irish Academy.
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.
