EIGHTH ORDINABY MEETING. 



73' 



When it is mean midnight at Greenwich, that moment it is mean 

 noon at the meridian 180° from Greenwich, as indicated by the solar 

 passage. Hence the anti-Prime Meridian practically becomes the 

 time-zero for the woi"ld. 



The initial instant of the twenty-fonr hours of each successive 

 Universal or Cosmic Day is the moment of mean solar passage on 

 the Anti-Prime Meridian. The first hour of the Cosmic Day is at 

 the solar passage on the meridian 15° westward This then becomes 

 the 1st hour meridian. The second hour of the Cosmic Day is at the 

 solar jDassage on the meridian 15° still further westward. This be- 

 comes the 2nd hour meridian. And so on in turn, each meridian^ 

 which is an exact multiple of 15° from zero becomes an hour meridian 

 corresponding in number with the numbers of the vSuccessive hours of 

 the Cosmic Day. 



The twenty-four hour meridians so determined come in the follow- 

 ing order, viz. :
