Glad that JH approves introducing Julian dates. Notes their use in American lunar tables. Positions of three new nebulae.
Encloses slips to show how he has incorporated the Julian dates. Agrees with the American lunar tables. The nebula in Taurus is invisible to William Lassell.
Was interested to receive the information regarding another missing nebula; would like to mention it at the R.A.S. The late George Bishop's observatory is now being rebuilt at Twickenham. Will return N. R. Pogson's table of Julian dates tomorrow. Has adopted the first of JH's suggestions.
Returns N. R. Pogson's tables. Has received a communication from [W.?] Lummis concerning a dark spot on the sun's disc. Has been unable to make any calculations yet.
[Jean] Chacornac found nebula in Coma Berenices that JH thought had disappeared. It is highly variable. Notes on nebulae of variable magnitude.
Positions of new comet, calculated from 'Florence observations.'
Compares positions for variable nebula in Taurus reported by several astronomers. Plans to incorporate JH's suggestion regarding Julian calendar into more convenient table of dates.
E. W. L. Tempel's 1860 discovery of nebula near Merope.
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.
