(M114) Among the Dyaks of North-West Borneo young men and warriors may not eat venison, because it would make them as timid as deer; but the women and very old men are free to eat it.(415) However, among the Kayans of the same region, who share the same view as to the ill effect of eating venison, men will partake of the dangerous viand provided it is cooked in the open air, for then the timid spirit of the animal is supposed to escape at once into the jungle and not to enter into the eater.(416) The Aino of Japan think that the otter is a very forgetful animal, and they often call a person with a bad memory an “otter head.” Therefore it is a rule with them that “the otter’s head must not lightly be used as an article of food, for unless people are very careful they will, if they eat it, become as forgetful as that creature. And hence it happens that when an otter has been killed the people do not usually eat the head. But if they are seized with a very strong desire for a feast of otter’s head, they may partake thereof, providing proper precautions are taken. When eating it the people must take their swords, knives, axes, bows and arrows, tobacco-boxes and pipes, trays, cups, garden tools, and everything they possess, tie them up in bundles with carrying slings, and sit with them attached to their heads while in the act of eating. This feast may be partaken of in this way, and no other. If this method be carefully adhered to, there will be no danger of forgetting where a thing has been placed, otherwise loss of memory will be the result.”(417) On the other hand the Aino believe that the heart of the water-ousel is exceedingly wise, and that in speech the bird is most eloquent. Therefore whenever he is killed, he should be at once torn open and his heart wrenched out and swallowed before it has time to grow cold or suffer damage of any kind. If a man swallows it thus, he will become very fluent and wise, and will be able to argue down all his adversaries.(418) In Northern India people fancy that if you eat the eyeballs of an owl you will be able like an owl to see in the dark.(419)
