which the world's standard unit measure of time is divided. The motion of the earth on 

 its axis brings each hour meridian in succession to its solar passage, and by numbering 

 them as described a complete coincidence is obtained between the hour meridians and 



the hours of the world's standard. For example, when the solar passage reaches hour 

 meridian number twelve it will be 12 o'clock, when it arrives at hour meridian number 

 seventeen it will be 17 o'clock, and so on for every meridian. Thus we realize the concep- 

 tion that the earth itself is the great standard chronometer, while the sun is the index to 

 point out the hours. 



This nomenclature by numbers generally assented to, the hour meridians which con- 

 stitute the sub-standards for universal time-reckoning would be distinguished as follows : 



Anti-Prime Meridian 180° east and west from Prime Meridian, " Zero." 



Hour Meridian 165" East longitude, number one No. 1, " Unus." 



150° " " two " 2, "Duo."
