The drug exhibited with the ceremonies by which the friendly spirit is induced to enter the body is entirely secondary and adjuvant, and is not supposed to be any more efficient in producing a cure than was the Old Testament incense of the Temple ritual in obtaining an answer to prayer. But the drug is often a really valuable medicine, and does cure the patient. Yet the native Christian must be forbidden to submit to its use, because of the invariably associated heathen ceremonies. The magician alone knows from what plant the drug came, and he positively refuses to administer it unless its associated ceremonies are carefully observed. For the Christian to consent to do that, is to "kiss the calves"[43] of idolatrous Israel, or to partake of the "meats offered to idols."[44] The manner of practising the white art by the magic doctor may be purely ritual without his making or the patient's wearing any material amulet, but the performance is none the less fetich in its character. According to the usual procedure an article is prepared with incantations referring to spiritual influences to be worn by the applicant either as a cure for an actually existing disease or any other expected danger, or, irrespective of disease, for the attainment of a desired object or for success in some cherished plan. Its application may be as limitless as the entire range of human desire. The first step in the process is the selection of an object in which to enclose the various articles deemed necessary to attract and please the spiritual being whose aid is to be invoked. In this selection it is not probable that superstitious or other moral consideration enters. It is simply a matter of taste as to shape or availability or convenience. The article usually chosen is a horn of a gazelle or young antelope, or of a goat. The ground for the choice is availability; those animals are common. The horns are preserved and are therefore always at hand. They are small, light, and easily carried. They are durable, not liable to rust and decay, as would be an article of vegetable origin, and they have a convenient cavity.
