At present, both in N and B, Hebrews is placed after 2 Thess., but in B there is also a continuous numeration of sections throughout the epistles, according to which I to 58 cover Romans to Galatians, but Ephesians, the next epistle, begins with 70 instead of 59, and the omitted section numbers are found in Hebrews.
A decimal system of numeration was used, with numbers going up to io,000.
Here we must bear in mind that Hebrew numeration always includes the day which is the terminus a quo as well as that which is term.
Arithmetic is supposed to deal with cardinal, not with ordinal numbers; but it will be found that actual numeration, beyond about three or four, is based on the ordinal aspect of number, and that a scientific treatment of the subject usually requires a return to this fundamental basis.
The representation of numbers by spoken sounds is called numeration; their representation by written signs is called notation.
