Regarding the pictures of the moon by M. M. Gussew. Gives details of the eclipse of 1860. Heliograph has been working at his observatory since February. G. Sabler has now left and will doubtless do good work when he receives his instrument from J. H. Dallmeyer.
Sorry to hear about JH's pain. Encloses notes from GA's testimony to parliamentary committee investigating changing standards of weights and measures. GA's work continues on 'veritable precessions.'
Encloses letter from G. J. Stoney, who had journal of WP's nebulae observations. Hopes WP's observations will be helpful for JH's proposed catalogue of nebulae.
Delighted with performance of WL's telescopes in Maltese climate. Invites JH to visit. Awaiting JH's catalogue of nebulae. Seeking assistant.
Describes galaxy-like gaseous nebula with interior elliptical ring.
More about the nebula catalog JH is preparing [see HA's 1862-3-12], and still wondering if there is some way HA's observations might be used.
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.
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.
