excuse of as true a Kleptomania as was ever established in the records of medical jurisprudence. I knew a man who had denied himself all but the bare necessaries of life to discharge debts into which another's fraud had plunged him, and whose sense of honor was so keen that when afflicted with chronic dyspepsia the morbid conscientiousness which is not an unusual mental symptom of that malady took the form of hunting up the owner of every pin he picked up from the floor, nor could he shake off a sense of criminality till he had found somebody who had lost one and restored it to him--yet on being prescribed opium for his complaint, his nature, under its operation, suffered such an entire inversion that the libraries, and on several occasions even the pocket-books of his friends were not safe from him, his larcenies comprising some of the most valuable volumes on the shelf and sums varying between two and twenty dollars in the porte-monnaie. "The Book-Hunter" writing of De Quincey, as you will recollect, under the _sobriquet_ of "Papaverius," describes the perfectly child-like absence of all proprietary distinctions which prevailed in that wonderful man's mind during his later years as regarded the books of his acquaintance, and the innocent way in which he abstracted any volume which he wanted or tore out and carried away with him the particular leaves he wished for reference. In many cases where the moral sense has suffered no such general _bouleversement_, the tendency which opium superinduces to look at every thing from the most sanguine point of view--the vague, dreamy habit of thought and the inability to deal with hard facts or fixed quantities--make it necessary to take an opium-eater's assertions upon any subject with a certain degree of allowance--to translate them, as it were, into the accurate expressions of literal life; but even where this necessity docs not exist, in cases sometimes though rarely met with, where opium has been long used without tinging any of life's common facts with uncertainty, an opium-eater can scarcely even be relied on for the exact truth concerning his own habit. He may be trusted without hesitation upon every other subject, but on this he almost always speaks evasively, and though about any thing else he would cut his hand off rather than say the thing that is not, will sometimes tell a downright falsehood. In most cases he has been led to this course by witnessing the agony or suffering the reproach with which the knowledge of his habit is received by his friends. He lies either in mercy to them or because the pangs which their rebuke inflicts would become still more intolerable if they knew the extent of his error.
