WIPO promotes its treaties database with an African question

Africa in 1886

Today's WIPO Wire invites readers to test their Treaty knowledge and asks:

"Which West African nation is named in the first paragraph of the 1886 Berne Convention?"

The answer to this question is Liberia. But Liberia is not the only African state mentioned in that paragraph. Can any reader name the other one?

WIPO's reason for asking is that it wants to publicise that fact that images of original treaties and information concerning them can be found via the WIPO-administered treaties database. One of its most endearing features is that you can click through from edition to edition, to see the version of each treaty text which replaces or is replaced by the one you are looking at.
