Please review TW's enclosed new book on civil time-keeping: How to Keep the Clock Right. [JH annotation: Answered 7 July.]

Was very happy to receive JH's remarks on his little logical work. Comments on this work. Is not satisfied with the logic of J. S. Mill. Has not seen [James] Haig's work yet, but hopes to read it on return from the Continent.

Extended comments on John Herschel's [JH's son] observations of the spectrum of the solar corona.

Thanks JH for his letter and package of his writings.

Cites various celestial appearances as a basis for concluding that the Milky Way takes the form, not of a disk or ring, but of a series of convolutions. Urges that the nebulae form part of the Milky Way rather than being separate universes, as many had suggested. Asks JH to critique these ideas.

Health is not good. Is not up to the theory of atoms. Have had broiling heat for many weeks.

A note to accompany a paper by FP on the prediction of occultations and eclipses.

Elaborates on his hypothesis that all forms of nebulae are part of the Milky Way and on his 'twisted-stream theory' of the Milky Way's structure. Favors view that dark matter is relatively common in space and that it extinguishes light from distant objects. Proposes method of measuring stellar diameters.

Is trying to get JH 2 copies of Physique sociale. Discusses additions. Addresses JH's comments concerning power of a supreme being. Sends 19th volume of annals of observatory and AQ's work on international congress on statistics.

Apologizes for not acknowledging JH's work. Asks for copy of Royal Geographical Society's papers. Discusses [François] Arago's work on light beams and prisms. Requests JH's opinion concerning [Wilhelm] Klinkerfues's theory of light, which seems to make [Augustin] Fresnel's hypothesis superfluous.

His letter has been forwarded. JH's correspondence with the Mint to which J. G. Hubbard refers has been published in the Report of the Commissioners on International Coinage 1868. Thinks expansion of mercurial amalgam is due to hydrogen. Hopes JH will accept a small medallion.

Sends 'first fruits' of Melbourne telescope in form of a letter from [A.] LeSueur and [R. L. J.] Ellery. Includes discussion of nebulae.

Thanks JH for his positive judgement of his work. Mentions that [François] Moigno could only say that it was anti-religious. Another work on statistics has emerged: Versuch einer Sozialethik, 2nd. vol., by Alexander von Ochingen. In few days leaves for international conference on statistics.

Accepts JH's objection to his method of measuring stellar diameters. Quotes an argument he had published suggesting the existence of a hierarchy of systems in an infinite universe. Discusses his studies of the relation of proper motions to the sun's motion. Asks JH's permission to publish JH's idea that some nebulae may be 'miniature' of the Milky Way.

Requests permission to print JH's response approving of fixed-telescope system for time-keeping set out in TW's new book on civil time-keeping, How to Keep the Clock Right.

Is very pleased that JH has accepted his little volume. Is sure JH would have made a success of a similar work. Behavior of animals.

Sending tables showing the periodical occurrences of solar spots, earthquakes, volcanic eruptions, etc.; comments on his theories regarding these.

Still worried about the meaning of some terms in John Herschel's [JH's son] paper [see GS's 1869-7-20].

In recent letter to the Times regarding international coinage, JH attributed viewpoint to Col. [J. T.] Smith that was in fact expressed by J. B. Smith, M.P. for Stockport. CW's remarks on valuation of coins.

Regarding JH's letter to the Times on the gold coinage question.
