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. As to boasting, the writer is well aware it is the worst policy imaginable for any one in search of admiration. He had better seem extremely modest, make apologies, advance with cap in hand on tiptoe. This is the way to captivate all little minds, without a single spark of genius, in a work. But the object of the author is to speak exactly as he thinks, with mathematical precision. Truth may seem severe when it is not, and he who speaks it, like the skilful surgeon at an amputation, calmly cuts, but only to save life or reputation. The man who will not do so is a moral coward. He is unfit to speak, or write, or act. He is selfish.
