Mostly involves arrangements about exchanges of papers and printing some of GP's in the Astronomical Society Memoirs.
Apologizes for delay in writing. Describes JH's travels across Europe back to England. Is sending GP copies of JH's papers in physics, mathematics, and astronomy, especially double stars. Describes a new instrument, a floating collimator, described by Henry Kater at the R.S.L. [Rough notes for a later letter on the back of part of this one.]
Is working on printing GP's theory of the moon. Has received packages containing the works of a number of English scientists, and wants to know cost so as to be able to reimburse JH. Wants to be remembered to Charles Babbage.
Is helping another scientist bring to publication a work on triangulation in the Alps. Comments on JH's idea of suspending an extremely long plumb bob at a particular precipice in the Alps [Foucault pendulum?]. GP does not believe the results would warrant the expense. Comments on the floating collimator [see JH's 1825-1-14], noting that he does not find it very helpful.
Is preparing a paper on planetary perturbations, which GP would like to send to the Astronomical Society for publication. Comments on JH's ideas on the subject of perturbations. Would the paper being in French be a problem? Comments on Henry Kater's method for finding the zero point in his meridian circle.
Pleased that Astronomical Society will publish GP's memoir (in French) [see GP's 1825-5-27]. Adds some comments for clarification on points in paper and makes arrangements for copies of the paper.
Inquires about the arrival of the memoir sent by GP to JH [see GP's 1825-7-28].
Is very concerned because JH's recent letter did not comment on the arrival of GP's memoir [see GP's 1825-10-24]. Comments on printing and arrangements for copies.
Is pleased that GP's memoir has finally arrived in London [see GP's 1825-11-19]. Indicates arrangements for paying for copies. Comments on GP's astronomical observations of the last several years, and on his method of making reductions.
Responds to receipt of sample impression of GP's memoir [see GP's 1825-12-3]. Comments on printing and paying arrangements, and to whom copies are to be sent. Comments on value of using an equatorial telescope as opposed to a meridian circle. [Some parts of the letter are illegible.]
Writes to correct error JH identified in GP's memoir [see GP's 1826-1-18]. Also asks to have two additional passages added to improve memoir. Intends to come to England next winter. Is including a list of corrections for the memoir [list is missing].
Has received a package of books from JH, some of which will be sent on as instructed. Is interested in the work of JH and James South on double stars. Also comments on parallax measure of the sun and on transits of Venus. Wants to respond to P. S. Laplace's theory of Jupiter and Saturn.
Is sending JH some of GP's work, some of it to be forwarded. Refers to a note by GP in some of F. X. von Zach's writings, which GP would like to have added to his memoir being published by the Astronomical Society. GP comments on the status of some of his own astronomical projects.
Still concerned about possible changes to GP's memoir [see GP's 1826-1-28] due to the work of P. S. Laplace. Comments on illness [?] of F. X. von Zach.
Is sending copies of a memoir on the triangulation of Savoy, prepared by GP and [Mr. ?] Carlini. Is including copies for other scientists and organizations.
Is sending the letter with the British ambassador [Augustus Foster] to the Court of Turin; Foster is much interested in science and in meeting JH. GP will be sending additional work that GP has done, and indicates further plans.
Is concerned to discover if the various packages of memoirs that GP sent have been received by JH. Talks about coming to London to present several papers.
Is preparing to observe the occultation of Aldebaran. Seeks JH's comments on GP's position on the perturbations of Jupiter and Saturn compared to P. S. Laplace's work on the same subject. Comments further on the sending and receiving of packages of memoirs.
Pleased to hear that JH received GP's memoirs. Comments on the nature of GP's response to an error on one of GP's memoirs on planetary perturbations. Expresses sorrow at the deaths of W. H. Wollaston, Humphry Davy, and Thomas Young.
