But while treatises upon this subject are by no means rare, they are not accessible, except to those scholars who are within reach of the largest libraries; and while all, or nearly all, indicate the association of these practices with sorcery and witchcraft, as well as with folk-medicine, no writer has hitherto ventured to suggest the distinctively religious derivation to be ascribed to them.
From the moment when the disgusting “Urine Dance of the Zuñis” was performed in the author’s presence down to the hour of concluding this work, a careful examination has been made of more than one thousand treatises of various kinds and all sizes, from the musty pig-skin covered black letter of the fifteenth century to the more modest but not less valuable pamphlet of later years. These treatises have covered the field of primitive religion, medicine, and magic, and have likewise included a most liberal portion of the best books of travel and observation among primitive peoples in every part of the world; not only English authorities, but also the writings of the best French, Spanish, German, Latin, Greek, Arabic, and Celtic authors are here presented, together with an examination of what has come down to us from leaders of Eastern religious thought and from the monastic “leeches” of the Anglo-Saxons.
A great number of examples of the use of stercoraceous remedies has been inserted under the head of “Therapeutics,” for two excellent reasons: first, to show that the use of such remedies was most widely disseminated; and secondly, to demonstrate that this use had been handed down from century to century.
Had any other course been followed, objection might have been raised that unusual remedies, or those of eccentric practitioners only, had been sought for and quoted for the purpose of proving that Filth Pharmacy was a thoroughly consistent and fully developed school in the science of therapeutics, from the most primitive times down to and even overlapping our own days.
A perusal of this volume cannot fail to convince the most critical that it has been written in a spirit of fairness as much as is possible to human nature, and without prepossession or prejudice in any direction.
The fact that so many citations have been incorporated in this compilation without comment, may be claimed as an additional proof of the unbiassed character of the work.
No collection of facts constitutes a science. All that can properly be done with facts not positively known to be related, is to place them, as here placed, in juxtaposition, leaving the reader to frame his own conclusions; by no other method can an author escape the imputation of distorting or perverting evidence.
The great number of letters received from distinguished scholars in all parts of the world, from Edinburgh to New South Wales, attests the interest felt in this treatise, and at the same time places the author under obligations which words cannot express. Special acknowledgments are due to:—
