The usages of folk-medicine form a wide subject, which would occupy many volumes such as the present; a mere bibliography of the literature could not be included in the number of pages here allowed. The gleaning, also, is in this case very imperfect; the greater number of such "Cures" would fall in that part of the subject here omitted, relating to the function of animals and plants. In this field, conceptions formerly operative have not yet disappeared; "the doctrine of signatures," that is to say, the rule that the healing object is indicated by its resemblance to the organ affected, has scarcely passed into oblivion, while popular systems of treatment are still based on rules not essentially different. In addition to this guiding idea, an exorcistic method has survived; in our folk-lore is retained the removal of the trouble in virtue of its transfer to another place or person. Especially in the significant case of warts, such rule of early medicine operates with full force. Here, as in other instances, the obscure influence of suggestion plays a complicated part; belief in the efficacy of any system of treatment appears sufficient to promote its effect. These charms are perhaps sometimes effective, even although no conscious attention is paid to the process; but to enter on this field would be foreign to the present discussion. It is sufficient to point out that in popular belief the preservation of the theory goes hand in hand with the survival of the practice.
Weather proverbs form an extensive body of popular observations, here only partially recorded. From the psychologic point of view, the principal interest attaches to the mental causes of these prognostics. Collectors have generally assumed that in this field experience is at the basis of a great part of the alleged knowledge. It may be so with a few of the simpler signs; yet, even in respect to these, great diversity is visible. In general, I should myself attach small importance to this consideration. Remarkable in man regarded as an intellectual being is the variation to be observed in the effect of experience. In certain relations of daily life the savage is as quick to learn, and as accurate in his judgment, as civilized man; mention need only be made of his skill in the hunt, and his intimacy with the forest. But under complicated conditions, whenever this action falls outside of daily habit, he appears incapable of profiting by observation; on the contrary, it is usually imagination which dictates presumed experience. The latter rarely corrects a superstition; as already remarked, discovery of error in the application of inherited theory is applied only to increase the complexity of the formula. Not until the existence of a means of record, and the formation of a body of observations capable of methodical arrangement, is an erroneous belief superseded, when the true causes of the events become manifest; of this principle ideas respecting the weather constitute good illustrations.
Students of this collection will be surprised by the number and vitality of formulas and beliefs relative to the moon. It is probable that the majority of the readers of the male sex will have no other associations with the newly born moon than that poetic sentiment which delights in the vision of the faint sickle silver through the twilight; if they possess any further association with the planet, it is likely to be no more than a vague dread of the effect of its radiance falling on a sleeper. Women, on the contrary, will remember that the moon should be first seen not "full face," but "over the the[TN-1] right shoulder;" they will be aware that with such vision may be united a wish, to which jesting fancy assigns a probability of accomplishment. But these, also, will be surprised by the discovery that lunar divination is maintained with profound seriousness, and that the honor paid to the orb is nothing else than a continued worship, still connected with material blessings expected from its bounty.
