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. When I first began the work I had by me about a dozen versions, being those best known, with two or three less common which chance had happened to throw in my way and I thought it possible that research might disclose, say an equal number unknown to me, so that the whole, with such notes as it might occur to me to write, would little exceed the size of a large pamphlet.
