Taking, then, the above advertisement to be true, or nearly so, down to the words "left leg" inclusive, (though I have some doubt if the blemish there implied amount to a positive lameness, or be perceivable by any but the nearest friends of John,) I would proceed thus:-- -- "Leans a little forward in his walk; his hair thick and inclining to auburn; his nose of the middle size, a little turned up at the end; lively hazel eyes (the contusion, as its effects are probably gone off by this time, I judge better omitted); inclines to be corpulent; his voice thick, but pleasing, especially when he sings; had on a decent shag great-coat with yellow buttons." Now I would stake a considerable wager (though by no means a positive man) that some such mitigated description would lead the beagles of the law into a much surer track for finding this ungracious varlet, than to set them upon a false scent after fictitious ugliness and fictitious shabbiness; though, to do those gentlemen justice, I have no doubt their experience has taught them in all such cases to abate a great deal of the deformity which they are instructed to expect, and has discovered to them that the Devil's agents upon this earth, like their master, are far less ugly in reality than they are painted.
I am afraid, Mr.Reflector, that I shall be thought to have gone wide of my subject, which was to detect the practical errors of physiognomy, properly so called; whereas I have introduced physical defects, such as lameness, the effects of accidents upon a man's person, his wearing apparel, &c., as circumstances on which the eye of dislike, looking askance, may report erroneous conclusions to the understanding.

But if we are liable, through a kind or an unkind passion, to mistake so grossly concerning things so exterior and palpable, how much more are we likely to err respecting those nicer and less perceptible hints of character in a face whose detection constitutes the triumph of the physiognomist! To revert to those bestowers of unmerited deformity, the framers of advertisements for the apprehension of delinquents, a sincere desire of promoting the end of public justice induces me to address a word to them on the best means of attaining those ends.

I will endeavor to lay down a few practical, or rather negative, rules for their use, for my ambition extends no further than to arm them with cautions against the self-defeating of their own purposes:-- 1.

Imprimis, then, Mr.Advertiser! If the culprit whom you are willing to recover be one to whom in times past you have shown kindness, and been disposed to think kindly of him yourself, but he has deceived your trust, and has run away, and left you with a load of debt to answer for him,--sit down calmly and endeavor to behold him through the spectacles of memory rather than of present conceit.
Image to yourself, before you pen a tittle of his description, the same plausible, good-looking man who took you in, and try to put away from your mind every intrusion of that deceitful spectre which perpetually obtrudes itself in the room of your former friend's known visage.

It will do you more credit to have been deceived by such a one; and depend upon it, the traitor will convey to the eyes of the world in general much more of that first idea which you formed (perhaps in part erroneous) of his physiognomy, than of that frightful substitute which you have suffered to creep in upon your mind and usurp upon it; a creature which has no archetype except in your own brain.
