in Egypt, since the effect of drinking its milk was believed to be leprosy. Such fancies may perhaps have been sometimes suggested by the observation that the eating of semi-putrid flesh, to which some savages are addicted, is apt to be followed by eruptions on the skin. Indeed, many modern authorities attribute leprosy to this cause, particularly to the eating of half rotten fish.(101) It seems not impossible that the abhorrence which the Hebrews entertained of leprosy, and the pains which they took to seclude lepers from the community, may have been based on religious as well as on purely sanitary grounds; they may have imagined that the disfigurement of the sufferers was a penalty which they had incurred by some infraction of taboo. Certainly we read in the Old Testament of cases of leprosy which the historian regarded as the direct consequence of sin.(102) (M24) Again, the rule that, after touching a pig, a man had to wash himself and his clothes, also favours the view of the sanctity of the pig. For it is a common belief that the effect of contact with a sacred object must be removed, by washing or otherwise, before a man is free to mingle with his fellows. Thus the Jews wash their hands after reading the sacred scriptures. Before coming forth from the tabernacle after the sin-offering, the high priest had to wash himself, and put off the garments which he had worn in the holy place.(103) It was a rule of Greek ritual that, in offering an expiatory sacrifice, the sacrificer should not touch the sacrifice, and that, after the offering was made, he must wash his body and his clothes in a river or spring before he could enter a city or his own house.(104) The Parjas, a small tribe of the Central Provinces in India, are divided into clans which have for their respective totems the tiger, the tortoise, the goat, a big lizard, a dove, and so on. If a man accidentally kills his totemic animal, “the earthen cooking-pots of his household are thrown away, the clothes are washed, and the house is purified with water in which the bark of the mango or _jamun_ tree (_Eugenia jambolana_) has been steeped. This is in sign of mourning, as it is thought that such an act will bring misfortune.”(105) If a Chadwar of the Central Provinces who has the pig for his totem should even see a pig killed by somebody else, he will throw away the household crockery and clean the house as if on the death of a member of his family.(106) The Polynesians felt strongly the need of ridding themselves of the sacred contagion, if it may be so called, which they caught by touching sacred objects. Various ceremonies were performed for the purpose of removing this contagion. We have seen, for example, how in Tonga a man who happened to touch a sacred chief, or anything personally belonging to him, had to perform a certain ceremony before he could feed himself with his hands; otherwise it was believed that he would swell up and die, or at least be
