sual quinary scale will be found,
with a few exceptions like those just instanced, to have the following
structure or one similar to it in all essential details: 1, 2, 3, 4, 5,
5-1, 5-2, 5-3, 5-4, 10, 10-1, 10-2, 10-3, 10-4, 10-5, 10-5-1, 10-5-2,
10-5-3, 10-5-4, 20. From these forms the entire system can readily be
constructed as soon as it is known whether its principal base is to be 10
or 20.

Turning first to the native African languages, I have selected the
following quinary scales from the abundant material that has been collected
by the various explorers of the "Dark Continent." In some cases the
numerals of certain tribes, as given by one writer, are found to differ
widely from the same numerals as reported by another. No attempt has been
made at comparison of these varying forms of orthography, which are usually
to be ascribed to difference of nationality on the part of the collectors.
