Admiral de Horsey has as his object the expla- 

 nation of the late Major-General Drayson's sys- 

 tem 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 ordi- 

 nary mathematical ability can calculate the obli- 

 quity 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 

 Ecliptio, and of the annual correction for obtain- 

 ing a standard rate of Bidereal time.
