Thanks for JG's Correlation of Physical Forces; JH is still uncertain about the nature of heat.
Thanks for volume three of WW's Plato edition. Responds to WW's comments on JH's translation of the first section of Homer's Iliad.
Has sent an R.S.L. membership application certificate for GA to sign and send on.
Is preparing a list of nebulae and their positions; does GA think anyone would print them?
Comments on barometric readings and the signaling process.
Suggests preparing an estimate of the cost of preparing and printing a nebula catalogue so JH can approach the R.S.L. [see GA's 1862-1-24].
Arranged for Maggie Maclear to be met after her arrival in England and for her trip back to Cape Town.
Notes ingenuity of JB's gravimetric balance. Astonished that it did not occur to anyone before. [Letter continues 5 Feb.:] Suggestion for improving torsion thread arrangement.
Comments on AH's chemical results and on an apparently anomalous sample of common salt being sent by JH; sends AH £5 for the month.
Outlines the differences between the telescope of his own father and that of Lord Oxmantown [William Parsons]. Comments on various lenses. Sends him a little work of his own on telescopes.
Mostly family news, concluding with concerns about family finances.
Comments on a number of chemical phenomena, and asks AH to analyze several solid samples; further, JH discusses meteor falls, with emphasis on the application of Newton's laws and terminal velocities.
JB's solution to torsion thread arrangement is simpler and more ingenious than JH's. Enquires about details of gravimetric balance. Pendulum measurements. Density of continents. Clarification of JH's privileges as foreign associate of Institute. Death of J. B. Biot.
Thanks for fine engravings; is concerned about the 'miraculous phenomena' depicted on some other people's engravings, 'especially American ones.'
Responds to some erroneous claims made at the Society regarding JH's views in meteorology, e.g., JH asserts his support for the Hadleian theory of winds.
Asks help of R.S.L. in reducing all observations to 1870 in JH's catalog of nebulae. Estimates cost at £10.
Has completed catalogue of nebulae and star clusters observed by Charles-Joseph Messier, JH's father, and JH. Requests R.S.L.'s help in 'reducing [them] to an epoch.'
Encourages AH in his intention to apply for a position at the University of Glasgow; gives AH advice about fulfilling his university responsibilities.
Is giving advice about AH's application for a position at the University of Glasgow, and indicating what kind of help JH can provide.
Asks what AD knows about the Andersonian Institution in Glasgow, which JH's son Alexander is considering as a place of employment. JH then deals with a problem in probability theory, and concludes the letter with a riddle.
