The mode of imposition, I shall explain in a fact as communicated by one of his most intimate friends, and leave the story itself to applaud his ingenuity:—He has (in a very respectable habitation) a small private room, to which every patient or messenger is conducted (upon a plea that the _doctor_ is not at home, or is particularly engaged) here an emissary (as if casually) asking certain questions, hears the whole story, examines the urine, and descends to particulars—the _doctor_ is in the adjoining apartment (calculated by a thin partition and certain openings, invisible to the unsuspecting visitor) where he minutely hears the entire conversation; the necessary secrets being obtained, he makes his appearance with the most commanding aspect; at this awful ceremony, the fascinated patient almost feels the effect of ANIMAL MAGNETISM; the approach of so much wisdom deprives him for a moment of speech, and the _poor devil_ undergoes a kind of temporary annihilation. An instance of this occurred not long since, when a country fellow having journeyed twelve miles to the doctor with a bottle of his wife’s _chrystal stream_, communicated the necessary particulars to the agent, when the doctor, in possession of the secret, made his appearance.—“Well, friend!”—“I have brought your honour my wife’s water, she could not _rest any longer_ without your _device_.”—“Your wife’s water—very well—let me see!—aye, I perceive she has _bruised her shoulder_.”—“Yes, Sir, she has indeed.”—“By this water (it is perfectly clear) she has _fallen down stairs_.”—“Yes, your honour!”—“She is not injured in any other part by the fall?”—“Only complains a little at the _bottom of her belly_, your honour.”—“Well, she fell from the top of the stairs to the bottom, _I see_?”—“No, your honour, she had gone down two steps before she fell.”—“Indeed! why then you have not brought me _all her water_.”—“No, your honour, there was _a little_ the bottle would not hold.”—“Why then, sirrah, the _two stairs_ are left behind.“——This circumstance, (of a thousand that might be quoted) is sufficient to demonstrate the ridiculous credulity of the multitude in all matters of quackery, and leaves us to lament, that the ignorance of one class, should become so wretched a prey to the deliberate villainy of another. The long experience you have had, in charging and posting your accompts, under different masters of equal judgment and experience, leaves little room for instruction under that head; it may however not prove inapplicable to remind you, it is no matter how incoherent or unintelligible the _writing_ is, provided your _figures_ are _bold_ and _conspicuous_; so long as you can convince them how much they _have to pay_, it is a total matter of indifference to you, how much they have _received_.
