366 MISCELLANEOUS PAPERS. 



5. That the unit measure defined as above he held to be a day absolute, and desig- 

 nated a cosmic day. 



6. That such cosmic day be held as the chronological date of the earth, changing 

 ■with the mean solar passage at the auti-meridian of Greenwich. 



7. That all divisions and multiples of the cosmic day be known as cosmic time. 



8. That the cosmic day be divided into hours, numbered iu a single series, one to 

 twenty-four (1 to 24), and that the hours be subdivided, as ordinary hours, into min- 

 utes and seconds. 



Note. — As an alternative means of distinguishing the cosmic hours from the hours 

 in local reckonings, they may be denoted by the letters of the alphabet, which, omit- 

 ting I and V, are twenty-four iu uumber. 



9. That until cosmic time be accepted as the recognized means of reckoning in the 

 ordinary affairs of life, it is advisable to assimilate the system to present usages, and 

 to provide for the easy translation of local reckonings into cosmic time, and vice versa; 

 that, therefore, in theory, and as closely as possible in practice, local reckonings be 

 based on a known interval in advance or behind cosmic time. 



10. That the surface of the globe be divided by twenty-four equi-distant hour-merid- 

 ians, corresponding with the hours of the cosmic day. 



11. That, as far as practicable, the several hour-meridians be taken according to 

 the longitude oftho locality, to regulate local reckonings, iu a manner similar to the 

 system in use throughout North America. 



12. That in all cases where an hour-meridian is adopted as the standard for regulat- 

 ing local reckonings in a particular section or district, the civil day shall be held to 

 commence twelve hours before, and end twelve hours after, the mean solar passage 

 of such hour meridian. 



13. That the civil day, based on the prime meridian of Greenwich, shall coincide 

 and be one with the cosmic day. That civil days on meridians east of Greenwich 

 shall be (according to the longitude) a known number of hours, or hours and min- 

 utes, in advance of cosmic time, and to the west of Greenwich the contrary. 



14. That the surface of the globe being divided by twenty-four equi-distant merid- 

 ians (fifteen degrees apart) corresponding with the hours of the cosmic day, it is 

 advisable that longitude be reckoned according to these hour-meridians. 



15. That divisions of longitude less than an hour (fifteen degrees) be reckoned in 

 minutes and seconds and jiarts of seconds. 



16. That longitude be reckoned continuously towards the west, beginning with zero 

 at tlie anti-prime meridian, twelve hours from Greenwich. 



17. That longitude generally be denoted by the same terms as those applied to cos- 

 mic time.
