The Yoruba scale, to which reference has already been made, p. 70, again
shows its peculiar structure, by continuing its vigesimal formation past
100 with no interruption in its method of numeral building. It will be
remembered that none of the European scales showed this persistency, but
passed at that point into decimal numeration. This will often be found to
be the case; but now and then a scale will come to our notice whose
vigesimal structure is continued, without any break, on into the hundreds
and sometimes into the thousands.
