NUMEEAL VALUE OF THE DAT SYMBOLS. 



63 



CIB— The Day Sign for 20. 



Though this symbol appears to be a compound, its elementary parts are not easily 

 determinable. That, in its entirety, it stands for 20 is established by the fact that it 

 is one of the signs employed to denote a clay, or days ; in which use it is always accom- 

 panied by a sign for 13, the product of the two being 260 — the number invariably 

 indicated by all the abstract day symbols.
