The Thibetians have adopted the use of the denary and duodenary cycles.
The notation is then said to be in the scale of which ten is the base, or in the denary scale.
There is no essential difference, however, between this and the denary basis.
The numeration was in the denary scale, so that it did not agree absolutely with the notation.
The words eleven and twelve have been supposed to suggest etymologically a denary basis (see, however, Numeral).
But the system has never spread; and the word “dozen” itself is based on the denary scale.
Each one was worth a denary, which was a coin worth about a shilling, or a quarter of a dollar.
