Believes the wires are 0.2" thicker than the old ones. Dust has settled on the parallel wires of the telescope. Advises how adjustment may be made to JH's micrometer for parallelism.

Has returned the drawings to [Andrew?] Smith not having received carte blanche to look at them. Bent one of the thick wires of the micrometer when taking out the plate, so has inserted another. The micrometer will be ready tomorrow. Clean Bermuda webs and two silver wires of 6" diameter.

Thanks TM for restoring JH's micrometer.

Believes that JH and TM can compile a better comet catalog together than they could separately.

Was necessary to reduce the whole of the sixth months' observations. More scanty than he desired but much of his time was taken up observing the comet stars. Is now busy with the comet stars. Does not send the precession as JH has them in his list.

Notes a discrepancy in TM's latest observations and those of Thomas Brisbane.

Observations of 'Comet stars.' Sends original 'Transit book.' Take care of it.

Congratulates TM on the birth of his son, George.

Mrs. Maclear is much better and has given birth to a son, their first.

A note along with a request from Niccolo Cacciatore for some observations that JH says he cannot make.

Sends the list of comet stars; the constants will be computed at the Observatory and will send a copy. Encloses letters from [W. H.] Smyth and others. Lead is being removed from the roof of the lantern.

Inquires about a star not found in TM's list of comet stars. Believes that their comet collaboration is going well.

Sends annotations to JH's 'sweeping sheet.' Complains of errors in ring micrometer.

Sends formulae for dealing with the apparent differences, in viewing the comet and compared star, due to the effects of parallax and refraction.

Sorry for surprise in church yesterday. Last minute request for JH and wife [to be godparents] was unplanned. Notes on 'Parallax & refraction.' Will soon observe all stars in [F. W.] 'Bessel's zone.'

Discusses their table of comet stars.

Much obliged for F. W. Bessel's zone. Thinks his own extra meridian observations of the comet will be respectable. Feels sure Fearon Fallows could not have approved of the supports of the dome. Has been promised the pleasure of inspecting the expenses of the Observatory. Captain J. E. Alexander and Dr. John Murray will call this morning for a parting cup of tea.

Calms TM about not having his comet observations published yet; those published so far are not of much value.

Intends to dispatch the packet to the Admiralty in a few days and await Francis Beaufort's instructions regarding the printing. TM's son would be grateful for the Herschels' gift could he express thanks himself. Would like the loan of the actinometer. Sends the dome observations.

Returns copies of the Comet observations and the formula for parallax and refraction. The 21st was a busy circle day. The mural circle is in better trim than ever. Sends a chronometer.
