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.
