Preface to 1850 Edition
I do not find it easy to get sufficiently far away from this Book, in the first sensations of having finished it, to refer to it with the composure which this formal heading would seem to require. My interest in it, is so recent and strong; and my mind is so divided between pleasure and regret — pleasure in the achievement of a long design, regret in the separation from many companions — that I am in danger of wearying the reader whom I love, with personal confidences, and private emotions.
