Various seeds, nuts, claws of animals, and other things are worn round the neck as ‘medicine’ of this kind. Sometimes it takes the shape of wedge-shaped wooden tablets, or bits of stick about an inch long, which are also seen strung on the band which people wear round the head as a remedy for headache—a kind of combination of ‘natural’ and ‘supernatural’ means, as the string is supposed to give relief by pressure. As for ‘offensive’ medicine, there are various kinds. Some are ‘buried against people’—usually in the form of horns—by the witch (_mfiti_) who wishes to do the said people a mischief. I have no doubt that horns are really sometimes buried with such intent; but it more frequently happens that they are _un_buried by the witch-detective who has probably the best of reasons for knowing where to find them. Then there is a very immoral kind of medicine which, like the Hand of Glory, enables thieves to steal without detection, by throwing the owners of the stolen property into a deep sleep, or even (adding insult to injury) forces them to answer, unconsciously, any questions as to the whereabouts of their wealth. There are several kinds of this charm, but I do not know the composition of any; though, in some parts of East Africa, a plant with the botanical name of _Steganotaenia_ is supposed to possess these marvellous properties. There is also a charm by means of which thieves can make themselves invisible; but as it might also enable honest men to escape from their enemies, it ought perhaps to have been enumerated in the first category. One kind, at least, of this medicine is the drug _strophanthus_ (obtained from a plant locally called _kombe_), and with this the chief Msamara poisoned himself in 1892, imagining that it would enable him to walk unseen out of prison at Fort Johnston. He had previously taken off all his clothes, reasoning that the drug would not make them invisible. I remember being told that native burglars (I understand that such exist, but cannot say I have come across them personally, and do not believe that they are common, except in the coast towns), when setting out for their night’s work, strip and oil themselves all over. This, I understood at the time, was to make it difficult for any one to get a grip of them, if caught; but it has since occurred to me that it was also part of the process for rendering themselves invisible—the medicine being applied externally as an unguent. Secret theft is looked on with horror, as probably connected with witchcraft. Natives are so ready to share everything they have with their neighbours, that a person who stealthily takes what he might have for the asking lays himself open to suspicion of yet darker dealings. It is the Bewitcher, the _Mfiti_, who is the great terror of native life.
