In order to make the text of this book available as quickly as possible, the text
alone has been scanned in from the original, omitting the diagrams, maps and photographs.
It may be possible to add these in a subsequent version. Also left for future versions
are italics and the dots under the letters e, o, and s, as described in the note
on orthography below. Yoruba specialists will easily be able to supply them, and
non-Yoruba specialists will not be particularly worried by their omission.
