"Help yourself to this work, dear reader, and if something does not bear the mark of perfection and accuracy, which I freely and sincerely confess; then know that this work, among the more serious concerns for the common good, has been brought to light by the author more unnoticed, in the off hours, than after a deeply thought-out manner of presentation. Should shadows appear here and there, or should some things be less clearly explained, then everyone will easily, according to his own insight, shed the necessary light on this, if one can only look at what we present with a reasonably friendly eye. Farewell."
