and call it a throwing knife. I believe it is entirely used for sacrificing. I do not believe you could throw it, as its curve and heavy weight at the back bring it round when you attempt to, and it is quite unlike the multi-bladed, real throwing knives of some middle Congo tribes. But it is perfectly adapted for killing animals by a blow behind the head, at the top of the spine, and this is the way I have seen it used, and if I remember right, Du Chaillu does not say that he himself saw it thrown. I have never seen any knife like it except in an illustration to Junker's Reiser im Afrika (1891, vol. iii. p. 122), where one very similar is figured among the knives of the Mungabatu.
There are several other implements of this cannibal tribe figured by Junker that have a great resemblance to the Fan things used for similar purposes, and I am much tempted to think that these two tribes are, if not identical, at least very nearly related. The same dwarf people, the pygmies, are in the Mungabatu region, and are fairly frequent in the forest among the Fans, and the north-east and east limitations of the Fans are not yet known.
I found to my great interest the same superstition in Congo Français that I met with first in the Oil Rivers. Its meaning I am unable to fully account for, but I believe it to be a form of sacrifice. In Calabar each individual has a certain forbidden thing or things. These things are either forms of food, or the method of eating. In Calabar this prohibition is called Ibet, and when, in consequence of the influence of white culture, a man gives up his Ibet, he is regarded by good sound ju-juists as leading an irregular and dissipated life, and even the unintentional breaking of the Ibet is regarded as very dangerous. For example, in buying a slave the purchaser always inquires what is the slave's Ibet, because if the slave were given his Ibet to eat, he would get ill; again, once when staying with my esteemed friend Miss Mary Slessor at Okyon, there arrived among her crowd of patients a small boy with a very "sick foot." On being asked from what it had arisen, instead of getting the usual answer, "picked up medicine on the road," the boy said he had broken his Ibet. Miss Slessor told me that shortly after
