Has been considering what principle should be followed in the computation of the orbits of double stars. Gives his views.
Obviously a ring of planets is being discovered. Congratulations on the discovery. Is the reading based on one night's observations only? Gives it a female name, possibly Iris.
Outlines the changes he would like to see in the column for Equinoctial Time in the Nautical Almanac.
About the naming of asteroids.
Suggests the name 'Clio' for asteroid No. 59. Gives a list of proposed names for asteroids.
Rejoices that RH is studying orbit of Mu2 Bootis. Suggests way to simplify calculations. Compares orbits for Gamma Virginis calculated by various observers. Notice of systematic errors.
Reports the disappearance of a nebula seen by William Herschel in Coma Berenices, but which H. L. d'Arrest did not locate in 1850.
Drawing attention to his prediction of the storms of 1838 and 1839.
Sends a copy of an ephemeris of Biela's comet for November and December.
Has just completed the orbit for the binary star Mu2 Bootis. Sends details. Could not send his notice of Biela's comet to W. R. Dawes as he did not know his address.
Is grateful for details of his method of calculating the orbits of double stars. Comments on some of his observations.
Will apply JH's principle at the first opportunity. Has made some successful observations of the star Epsilon Arietes. Intends observing Castor on every fine evening.
Communicating the elements of Castor and Corona by JH's method. Comments on these readings.
Sending him the elements of the new planet Astrea. Orbit is based on the Berlin observations. Differs from those given by J. F. Encke.
Regarding the strange appearance of the comet of Biela. Will observe the double star as soon as he has an opportunity.
Is obliged for his notice of the separation of Biela's comet; has sent extracts to H. C. Schumacher. Sends some observations made that evening. [Francesco] de Vico announces a new comet; so far he has been unable to trace it.
Has not been able to secure any angles of Gamma Virginis due to poor weather. Perplexed over the difference between J. H. Mädler and W. R. Dawes. George Bishop will be pleased to send any measures he may require.
Sends his observations of y Cygni. Comments on the differences in the readings of various observers. Still unable to observe the double star JH requested, but the weather has been poor.
Obtained first rate measures of the double star on 31 May, but since then the atmosphere has been hazy and so unable to send any further measures. Thinks it worthwhile to observe all the stars in Cassiopeia and Ophiuchus.
Elements of the new comet observed at Regent's Park.
