The corresponding subdivisions of the solar day will be 

 as follows : 



New denominations. Old denominations. 



lday =100000 s =20 h = 24 h =86400 3 



1 demidie = 50000 s =10 h = 12 h 



1 quartidie = 25000 s = 5 h - 6 h 



1 decidie = 10000 s = 2 h =2 h 24 m 



J decidie - 5000 s = l h =l oure=50 m. =l h 12 m 

 lcentidie = 1000 s = 14 m 24 s 



1 millidie = 100 s = l m =l minute = l m 26 s ,4=86 s ,4 

 lbillidie — 10 s =8 S ,64 

 1 trillidie = l s = 1 secunde =0 8 ,864 



It will further be perceived that for the sake of symmetry 

 in nomenclature, the common system of numeration should 

 be changed for the following : 



l=units or uniards, 

 10=tens or deciards, 

 100=hundreds or centiards, 

 1000=thousands or milliards, 

 10000=billiards, 

 100000=trilliards, 

 1000000=quadrilliards, 

 10000000=quintilliards, etc. 



After the above scheme, both the angular and linear 

 dimensions of space will be submitted to decimal jurisdic- 

 tion, and be referred to a cosmical standard unit of length 

 consisting of the equatorial pendulum that shall make 

 100000 oscillations in a sidereal day. Although a trifle 

 shorter than the pendulum in present use, the metre thus 

 determined will still a little exceed 39 inches in length, and 

 therefore will not disturb the convenient size of our instru- 

 ments of practical measurement. 



As both religious and social convenience appear to be 

 best consulted by retaining inviolable the custom of group-
