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. The author has been careful not to include new untried methods, for of these but'a small number will last, and a text-book should contain nothing as yet not well tested by friends and foes. It is the introduction of new methods which renders some books even dangerous to the man who buys but one.
