Cannot leave the instrument with Edward Troughton later than Saturday. Perhaps Troughton had better leave the instrument in the box until GE calls.

The Miss Edgeworths will prolong their visit until Friday in order to visit Slough. George Dollond has sent the radii of the crown lens. Will JH breakfast with the Katers on Friday?
The Miss Edgeworths have changed their plans again in order to visit Portsmouth, but will arrive at Slough on Sunday morning. Hopes the Herschels can still breakfast with the Katers on Friday.
The comet is not visible. All is ready for its observation. How is the Cambridge observatory progressing? Comet still not visible. Wishes he had a good telescope.
Will not be able to pay a visit as children have whooping cough. Has been demonstrating his calculating machine. Hopes to see him at the Greenwich visitation.
JH has been appointed a Lay-fellow. It entails no duties. The present body regards it as an honor to retain JH's name.
Outlining the circumstances in which J. N. Vallot was elected an Associate of the Astronomical Society. Has only received one letter from Vallot.
Mentions meeting [W.] Herschel in 1816. Recalls receiving catalog from Caroline Herschel, which he then gave to the Munich observatory. Looks forward to meeting JH and 'sharing love of truth.' Sends chemistry and physics papers. Discusses code for electromagnetic signals and its origin.
Thanks for sending your catalogues. Requests duplicates. Has made annotations indicating the 'quantity which Mr. [F. W.] Bessel's Instrument places the stars to the south of my determinations.' Cannot yet explain discrepancy. Unable to determine a parallactic shift for Alpha Lyrae, Alpha Aquila, or Gamma Draconis.
Thanks JH for extract from a letter from [J. J.] Littrow. Discusses in detail positional determinations of various stars he has made, attempting to determine whether errors of either observations or computation have entered into his results. Reports that in general there is substantial agreement between determinations made by JP and those made by John Brinkley at Ireland's Royal Observatory. Mentions solar observations at Greenwich.
Would like very much to see JH as soon as possible. Has an instrument of [J. C.?] Schenk to show him. There is one on the way to him now from Paris.
Has received letters from the Admiralty, which have allayed all his previous distress. Is to receive two telescopes. Weather has been unsuitable for observations.
Further regarding the transmission of papers abroad. Encloses a copy of his own paper on the formula of J. J. Littrow. Astronomical matters.
[J. C.?] Schenk has reason to be grateful to JH for all his assistance. Schenck's friends can now judge whether it will be expedient to bring Schenk to London to set up in business. Awaits anxiously the verdict of Edward Troughton.
