These articles recovered from the MSS. of De Quincey will, the Editor believes, be found of substantive value. In some cases they throw fresh light on his opinions and ways of thinking; in other cases they deal with topics which are not touched at all in his collected works: and certainly, when read alongside the writings with which the public is already familiar, will give altogether a new idea of his range both of interests and activities. The 'Brevia,' especially, will probably be regarded as throwing more light on his character and individuality--exhibiting more of the inner life, in fact--than any number of letters or reminiscences from the pens of others would be found to do. It is as though the ordinary reader were asked to sit down at ease with the author, when he is in his most social and communicative mood, when he has donned his dressing-gown and slippers, and is inclined to unbosom himself, and that freely, on matters which usually, and in general society, he would have been inclined to shun, or at all events to pass over lightly. Here we have him at one moment presenting the results of speculations the loftiest that can engage the mind of man; at another making note of whimsical or surprising points in the man or woman he has met with, or in the books he has read; at another, amusing himself with the most recent anecdote, or _bon-mot_, or reflecting on the latest accident or murder, or good-naturedly noting odd lapses in style in magazine or newspaper. It must not be supposed that the author himself was inclined to lay such weight on these stray notes, as might be presumed from the form in which they are here presented. That might give the impression of a most methodic worker and thinker, who had before him a carefully-indexed commonplace book, into which he posted at the proper place his rough notes and suggestions. That was not De Quincey's way. If he was not one of the wealthy men who care not how they give, he was one who made the most careless record even of what was likely to be valuable--at all events to himself. His habit was to make notes just as they occurred to him, and on the sheet that he chanced to have at the moment before him. It might be the 'copy' for an article indeed, and in a little square patch at the corner--separated from the main text by an insulating line of ink drawn round the foreign matter--through this, not seldom, when finished he would lightly draw his pen; meaning probably to return to it when his MS. came back to him from the printer, which accounts, it may be, in some measure for his reluctance to get rid of, or to destroy, 'copy' already printed from. Sometimes we have found on a sheet a dozen or so of lines of a well-known article; and the rest filled up with notes, some written one way of the paper, some another, and now and then entangled in the most surprising fashion. In these cases, where the notes, of course, were meant for his own eye, he wrote in a small
