as to medicine whatever. No doubt it was mere casual luck at first that tried these springs and found them answer. Somebody by accident tried them and by that accident was instantly cured. The chance which happily directed men in this one case, misdirected them in a thousand cases. Some expedition had answered when the resolution to undertake it was resolved on under an ancient tree, and accordingly that tree became lucky and sacred. Another expedition failed when a magpie crossed its path, and a magpie was said to be unlucky. A serpent crossed the path of another expedition, and it had a marvellous victory, and accordingly the serpent became a sign of great luck (and what a savage cannot distinguish from it--a potent deity which makes luck). Ancient medicine is equally unreasonable: as late down as the Middle Ages it was full of superstitions founded on mere luck. The collection of prescriptions published under the direction of the Master of the Rolls abounds in such fancies as we should call them. According to one of them, unless I forget, some disease--a fever, I think--is supposed to be cured by placing the patient between two halves of a hare and a pigeon recently killed.[7] Nothing can be plainer than that there is no ground for this kind of treatment, and that the idea of it arose out of a chance hit, which came right and succeeded. There was nothing so absurd or so contrary to common sense as we are apt to imagine about it. The lying between two halves of a hare or a pigeon was a priori, and to the inexperienced mind, quite as likely to cure disease as the drinking certain draughts of nasty mineral water. Both, somehow, were tried; both answered--that is. Both were at the first time, or at some memorable time, followed by a remarkable recovery; and the only difference is, that the curative power of the mineral is persistent, and happens constantly; whereas, on an average of trials, the proximity of a hare or pigeon is found to have no effect, and cures take place as often in cases where it is not tried as in cases where it is. The nature of minds which are deeply engaged in watching events of which they do not know the reason, is to single out some fabulous accompaniment or some wonderful series of good luck or bad luck, and to dread ever after that accompaniment if it brings evil, and to love it and long for it if it brings good. All savages are in this position, and the fascinating effect of striking accompaniments (in some single case) of singular good fortune and singular calamity, is one great source of savage religions.
