The _mesticas_ of the Malays represent a class of stones differing in important respects from the various types of bezoars. A principal distinction is that the _mesticas_ are not supposed to owe their origin to pathological conditions in the organism wherein they occur, but rather to a superabundance of the normal and healthy constituents of the animal or plant. It is probably due to this that the virtues of these particular concretions are rather talismanic than therapeutic, and that they are believed to endow the finder, or one who receives them by gift, with courage, immunity from injury, and also with cunning and shrewdness in the affairs of life. Especially by warriors are these stones highly valued, for they are supposed to protect the wearer from wounds; indeed, this belief sometimes went so far as to lead the Malays to think that absolute invulnerability was conferred on one who carried several of them bound so closely to the skin that in some cases they even penetrated the flesh. The typical _mestica_ is described as a hard stone, brilliant but seldom transparent; it is found in the flesh or fat, in the heart or on the legs of animals, and also sometimes in plants.[31] Rumphius declares that many extraordinary cases were related of warriors who could not be injured by any weapons until the _mestica_ had been cut out of their flesh, wherein it had become embedded. Indeed, he states that Dutch officers of proved veracity had confidently asserted that they had encountered such men among their native antagonists. While Rumphius feels himself therefore forced to admit the truth of the invulnerability of these men, he hastens to add that such powers could not be inherent in any piece of stone, but must owe their origin to diabolical agencies.[32] The fact that the Mohammedans had their _mesticas_ blessed by the priests of their faith, and burned incense beneath them on Fridays, the Mohammedan equivalent of the Christian Sunday, did not probably shake the belief of Rumphius that the Devil had something to do with these substances. The medicine-men of the Kainugá Indians of Paraguay mutter incantations over the bodies of the sick, and then, after many struggles and contortions, proceed to extract stones from their mouths, claiming that they have taken the patient’s disease into their own bodies, the stones being regarded as the seat of the ailment. In one case, the medicine-man produced five of these stones before the patient admitted that his pain was relieved. After the cure was completed the sorcerer was clever enough to feign extreme exhaustion, as though his vital forces had been subjected to a tremendous strain.[33] [Illustration: INDIAN MEDICINE-MEN From “Histoire Générale des Cérémonies Religieuses de tous les Peuples du Monde,” by Abbé Banier and Abbé Mascrier, Paris, 1741. ]
