About changes in metals due to frequent expansions and contractions, and about the health of JH's son William.
Discusses at length the means of calculating the mean daily rainfall in India, and comments on son John's work in geodesy.
Most of the letter is devoted to a mathematical derivation to show that part of son John's work on errors in geodetic observations is in error; however, part is highly praised by JH. Remainder of letter is clearly intended as a morale booster for John.

Has heard from Emma, son William's wife, that the solar eclipse will occur in the rainy season, and thus will not likely be visible [see JH's 1867-9-29]; JH is wondering if the equipment from the R.S.L. arrived safely.
Speaks of the awkwardness of some telescopic instruments, but urges son John to persevere; comments favorably on daughter Amelia's prospective husband, Thomas Wade, and comments disparagingly about the government's introduction of a metrication bill.
Comments on son John's spectroscopic and telescopic observations, and encourages observing a particular nebula, as it has been reported as having changed shape since JH observed it in the 1830's.
Is anxiously awaiting details of son John's observations of the solar eclipse in India; JH sends details of sunspots observed by JH on 18 Aug., and concludes with family news.
Talks about problems of observing nebulae—one of which seems to have changed—and one of which is in the catalogue and does not seem to exist.
Asks son John to stop at the British Museum and get the completion of a quotation JH needs; also asks John to pick up JH's R.S.P.T. copies not picked up recently.
