Fascination was excited by touch, voice, and look. The fascination by touch was simply mesmerism, or rather the biology of the present day, in an undeveloped stage. There were said to be four qualities of touch,--_calidus, humidus, frigidus, et siccus_, or hot, cold, moist, and dry,--according to which persons were active or passive in the exercise of the fascinum. Its function was double, by raising or by lowering the arm,--"_modo per arteriæ elevationem, modo per ejusdem submissionem_" says the worthy Vairits; "for," he continues, "when the artery is thrown out and is open, the spirits are emitted with wonderful celerity, and in some imperceptible manner are carried to the thing to fascinate it. And because the artery has its origin in the heart, the spirits issuing thence retain its infected and vitiated nature, and according to its depravity fascinate and destroy." This power of touch is recognized in all history and in all climes. All who saw Christ desired to touch his garment, and so receive some healing virtue; and his miracles of cure he almost always performed by his hand. When the woman who had the issue of blood came behind him and touched him, Jesus asked who touched him, and said,--"Somebody hath touched me; for I perceive that virtue is gone out of me." It has always been a popular superstition that the scrofula could be cured by the touch of a king or of the seventh son of a seventh son. The old belief that the body of a murdered man would distill blood, if his murderer's hand were placed on him, is also of the same class. Descending to the sphere of animals, we find some curious facts having relation to this power. The electrical eel, for instance, has the faculty of overcoming and numbing his prey by this means. And among the Arabs, according to Gerard, the French lion-killer, whoever inhales the breath of the lion goes mad.
