On the dynamics of atmospheric pressure and the pressure on clouds and birds.

As JH is preparing a catalogue of all known nebulae, would WL please provide a complete listing of all he has seen.

Sends another section of JH's Iliad translation. Regrets he cannot come to the Cambridge B.A.A.S. meeting. Sends lines of the Iliad translated by Augustus DeMorgan.

Times of 12 May called for remedy to industrial pollution. In 1838 JH visited soda production plant near Newcastle and suggested profitable modification to fume chimneys that removed harmful vapors and generated useful compounds.

Calls public attention to an inexpensive process JH devised in 1838 to eliminate noxious acid fumes coming from manufacturers of soda.

[Responding to JC's 1862-5-26], discusses JH's argument against the eternal self existence of matter. Gives reference to where argument appears in JH's Prelim. Discourse.

Comments on several nebulae, and on GA's receiving an honorary degree [from Cambridge University].

Provides the information in response to GA's request for the position of one nebula [see GA's 1862-5-27].

Hopes AD will be successful in his projected paper on the infinity of magnitude. Does not recollect the paper by J. J. Sylvester. Has had a letter from Manchester on his own theory of eternal existence.

Outlines the early life of his father, Sir William Herschel, and shows that the cutting received from the Stroud Journal was inaccurate. [Marked 'not sent.']

Gives details of William Herschel's youth, to correct errors in TP's anecdote about WH in Stroud Journal.

The family is complaining about not having any news from AH; comments about AH's explanation of the color of copper sulfate by twilight.

Has just received the Stroud Journal and TP's letter. Thinks it a fair and proper thing that TP has done. His own letter had no sinister insinuation.

JH regrets he will not have time to review paper on Indian meteorology.

Reports on and deems fit for publication [William] Hopkins's paper [R.S.P.T., 153, 677-] on theory of motion of glaciers.

Thanks WP for WP's paper on nebulae and on WP's giant reflecting telescope. Comments on and/or raises questions about various nebulae.

Thanks AH for the chemical analyses [see JH's 1862-2-13]; gives fatherly advice about spending, or not spending, money.

Expresses concern about son John's loneliness in India, and so JH proceeds to tell him of the Great Exhibition of 1862, and about scientific work being done such as improvements in meteorology, solar photography, and the work being done on JH's catalogue of nebulae. No decision has been made about the Edinburgh professorship for which son Alexander has applied.

Sends £10 to GA, exhausting grant from R.S.L. GA's estimate of 5600 nebulae was too high. Recommends asking R.S.L. for additional £50.

The R.S.L. grant is almost used up; how much more money will be needed for the nebula catalogue [see GA's 1862-6-25]?
