Ladies and Gentlemen, -I have undertaken to speak to you this evening on what is called the Science of History. I fear it is a dry subject; and there seems, indeed, something incongruous in the very connection of such words as Science and History. It is as if we were to talk of the color of sound, or the longitude of the Rule-of-three. Where it is so difficult to make out the truth on the commonest disputed fact in matters passing under our very eyes, how can we talk of a science in things long past, which come to us only through books? It often seems to me as if History was like a child's box of letters, with which we can spell any word we please. We have only to pick out such letters as we want, arrange them as we like, and say nothing about those which do not suit our purpose
