ABSTRACT

I have now mentioned all the books which I have published, and that these have been the milestones in my life, so that little remains to be said. I am not conscious of any change in my mind during the last thirty years, excepting in one point presently to be mentioned; nor indeed could any change have been expected unless one of general deterioration. But my father lived to his eighty-third year with his mind as lively as ever it was, and all his faculties undimmed; and I hope that I may die before my mind fails to a sensible extent. I think that I have become a little more skilful in guessing ['ight explanations and in devising experimental tests; but this may probably be the result of mere practice, and of a larger store of knowledge. 1 have as much difficulty as ever in expressing myself clearly and concisely; and this difficulty has caused me a very great loss of time; but it has had the compensating advantage of I forcing me to think long and intently about every sentence, and thus 1 have been often led to see errors in reasoning and in my own observations or those of others.
