By way of on-line background for the first topic

Makinde has a book (African Philosophy, Culture, and Traditional
Medicine — 1988, Ohio UP) about the topic but I can't find it on the
web. (It is in Questia but you have to subscribe to that.)

There is a very brief discussion of it by Hallden here, pages 43/44:

Hallden says a lot of it is about divination. There is most of the
chapter on Yoruba divination in the Companion to African Philosophy at
Google books too:

- Google books is a pain - you have to go to the ToC and click on
chapter 22 to reach it.
