PREFACE.
While permitting this Lecture to go before the public, we are aware that many persons may be prejudiced against us and our cause, before having given the subject reasonable thought. We would remind such persons, if such there be, that we are all human beings, placed here to aid, encourage and "love one another." Hence, we do most humbly implore them to peruse and digest the contents of this discourse without bias; and, if after having done so, they can point out any doctrines which are not in strict accordance with sound scientific laws—we will most sincerely thank them for such criticism; still, we do not deem it just that a doctrine should be denounced without a legitimate cause. However, we claim to have ample reason to dislike and disapprove of "quackery"—simply because "life" is very precious to us as well as to our children and friends whom we love most affectionately. And we deem this glorious boon too valuable to trifle with; we equally consider the "cure of human ills" too serious for jesting or for hypothetical experiment!
Philadelphia, Pa., January 5th, 1860.
