Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Some few of the ideas thus brought forward I have gleaned from writings on the subject, many have come from my teach- ers and other friends in the profession, while the remainder have occurred as the fruit of my own labors. None of them, therefore, are advocated merely from a theoretical course of reasoning, but all have been tried in the furnace of actual experience, and have not been found wanting.
