Would like JH to add his signature to Hind's certificate for the R.S.L., and then forward it to G. B. Airy.
Explaining the discrepancy in the Nautical Almanac; will endeavor to make a clearer explanation in the next edition. Returns JH's son's memorandum.
Sees that JH mentions 'the longitude of perihelion on the ecliptic' as one of the elements he would like to have in the case of the small planets. Would like his advice.
Comments on JH's advice regarding the 'longitude of perihelion in the ecliptic.'
Explaining some of the signs in the enclosed table. Has sent the Nautical Almanac for 1867.
Sending the revision of the first half sheet for the 1867 supplement containing the latest elements of the small planets.
JH's letter went to the old address, which accounts for the delay. Regarding his query, gives date of the conjunction of the planets.
Regarding the comet seen at Melbourne (Australia), may be the 1843 comet discussed by JH in his Outlines Astr. Comments on this.
Further regarding the southern comet; does not think it can be the 1843 one until he receives further observations.
Sending the elements of 79, 81 and 82; is not certain if N. R. Pogson has sent the orbit for No. 80. It is reckoned in the same way as in the last edition of JH's Outlines Astr.
Thinks that E. W. L. Tempel's comet may be connected with that of Biela. Comments on this.
Regrets his reply [to Hind's 1866-1-30?] is late owing to absence on an excursion. Has not heard that either comet has been perceived. Has not seen Otto Struve's remarks.
[John?] Farley has just given him the readings for the minor planets. Encloses these and also readings for the major planets from U. J. J. Leverrier.
Sends photograph of a medal lately struck in Paris to commemorate the discovery of 100 asteroids, on which Hind appears.
His last note on the Julian period puzzled him. Has not taken many double star measurements, but will send on a few later. Has not finished the ecliptical charts yet. Regarding a planet more distant than Neptune.
Has calculated the ecliptic of Thucydides. Comments on this and the reading given by E. W. Hartwig. Regarding the 7 eclipses of the sun during the past 30 years. G. Bishop's assistant (W. Plummer) is investigating the orbit of the great comet of 1861. Nautical Almanac for 1874 delayed due to extra work on the transit of Venus.
Forgot to call his attention to the column regarding the Julian period in the Nautical Almanac. Something strange about the neighborhood of R. Leporis. He has no doubt seen the table of Julian dates in the Connaissance des temps.
Sends calculation of the Transits of Venus in 2004 and 2012. Cannot find any record of new double stars. Is in doubt about R. Leporis. Quotes an historical incident regarding an eclipse of the sun and the removal of Mahomet's pulpit. Did F. X. von Zach make his calculations himself?
Gratitude for Cape Results. Special comments on JH's 'method of sequences' and cometary theory. Refers to article on Halley's Comet in Astronomische Nachrichten. Reports observations of Saturn's satellites and orbit of Gamma Virginis.
Annibal de Gasparis's new planet Psyche. Alexander von Humboldt selected its name. Other new planet, found by [C. Robert] Luther, was named Thetis by F. W. A. Argelander. Detected new nebula on 26 Apr. Nervous trouble interrupting Hind's search for planets.
