PREFACE.
How does it work? This question has been put to me so often by persons
young and old that I have at last decided to answer it in such a manner
that a much larger public than that with which I have personal
acquaintance may be able to satisfy themselves as to the principles
underlying many of the mechanisms met with in everyday life.
