Admiral de Honey has as his object the explanation of the late Major-General Drayson's system of the second rotation of the earth, and of the date and duration of the last Glacial Period. It attempts also to show how any person of ordinary mathematical ability can calculate the obliquity of the Ecliptic, the procession of Equinoxes, and the right ascension and declination of the fixed stars for any year, past, present, or future. It also shows the cause, amount and tables of the annual variation of the mean obliquity of the Ecliptic, and of the annual correction for obtaining a standard rate of sidereal time.
