In view of the additional costs, should the nebula catalogue be reduced to a 'working list', or should JH go back to the R.S.L. for more money [see GA's 1862-6-29]?

Suggests Mr. Rüppell apply to Council of R.A.S. for copy of medal. Mentions the head on the medal is [Isaac] Newton's, not William Herschel's.

Sorry to hear of his illness. Answers to his queries regarding the colloid state of ice. Cannot agree about metals of alkalis and earths uncombined in the earth.

After collecting and reducing all nebula observations by JH and William Herschel, JH objects to GA's suggestion that JH should pay for calculations needed to prepare catalogue of nebulae. Hesitates to request additional funds from R.S.L.

Writes to ask EL a series of questions about probabilities related to shooting at targets, with variations in the size and shape of the targets.

Discusses various etymologies, some coming out of JH's efforts to translate Homer's Iliad. Also discusses a book sale and some anagrams.

Withdraws article that JH submitted to Cornhill Magazine because, as GS noted, it was meant for different class of readers. But asks for 250 copies to be printed for JH's private circulation.

Seeks state of the nebula catalogue so an accurate estimate of the remaining costs may be made [see GA's 1862-8-1].

On preparing convenient small tables to be carried with one; comments on concept formation.

JH's catalog of nebulae, reduced to 1880 as originally planned, is nearly complete and consumed all of £20 granted by R.S.L. Seeks £16 more to expand catalog and reduce data to 1860, as recommended by G. B. Airy.

Needs to know soon if R.S.L. will approve grant to expand JH's catalog of nebulae. Otherwise G. B. Airy will dismiss man employed to do those computations. [JH annotation: Sent similar letter to G. G. Stokes on same date.]

Expects R.S.L. to provide additional money, but JH will finish work himself rather than go over the amount granted [see GA's 1862-8-12].

Thanks for the pamphlet on the Figure of the Earth, but regrets he cannot agree with its conclusions. Points out some of the more serious errors.

Congratulations on the balloon ascent to 30,000 feet by James Glaisher and Henry Coxwell. Suggests far greater heights are possible using compressed oxygen to breathe and the 'Peruvian coca leaf' [cocaine] as a source of strength.

Quotes report of limitations in JW's new artillery shell for penetrating ironclad vessels. Recounts JH's [Apr. 1836] experiments at Cape of Good Hope to increase explosive power of gunpowder by adding [Luke] Howard's fulminating mercury.

Sends JH's translation of Book II of Homer's Iliad (1862). Hopes to publish it in Cornhill Magazine. Three reasons for wanting it to appear soon.

Thanks for superb new information about nebulae in William Herschel's list. Wishes Alexander Herschel could serve as [WL]'s assistant in Valetta. Success of JH's son Alexander in chemistry and meteor research.

Has photographs of September 23 . Desires half pictures 'with the sun's limb in the middle of the view.' Cannot yet draw conclusions about the notches of the limb.

Nebulous nature of some stars. Recent reports on variability of some nebulae.

Reduction of JH's catalog of nebulae will not be completed before Christmas. HA's success in discovering nebulae and novae. Has compared positions of all nebulae observed by both JH and William Herschel; very few show evidence of shift. Thanks for offering HA's observations, but space in catalog is too limited.
