of intellect, will then coolly demand the pre-existence of intellect, as the cause and ground-work of organization. There is in truth but one state to which this theory applies at all, namely, that of complete light-headedness; and even to this it applies but partially, because the will and reason are perhaps never wholly suspended. A case of this kind occurred in a Roman Catholic town in Germany a year or two before my arrival at Goettingen, and had not then ceased to be a frequent subject of conversation. A young woman of four or five and twenty, who could neither read, nor write, was seized with a nervous fever; during which, according to the asseverations of all the priests and monks of the neighbourhood, she became possessed, and, as it appeared, by a very learned devil. She continued incessantly talking Latin, Greek, and Hebrew, in very pompous tones and with most distinct enunciation. This possession was rendered more probable by the known fact that she was or had been a heretic. Voltaire humorously advises the devil to decline all acquaintance with medical men; and it would have been more to his reputation, if he had taken this advice in the present instance. The case had attracted the particular attention of a young physician, and by his statement many eminent physiologists and psychologists visited the town, and cross-examined the case on the spot. Sheets full of her ravings were taken down from her own mouth, and were found to consist of sentences, coherent and intelligible each for itself, but with little or no connection with each other. Of the Hebrew, a small portion only could be traced to the Bible; the remainder seemed to be in the Rabbinical dialect. All trick or conspiracy was out of the question. Not only had the young woman ever been a harmless, simple creature; but she was evidently labouring under a nervous fever. In the town, in which she had been resident for many years as a servant in different families, no solution presented itself. The young physician, however, determined to trace her past life step by step; for the patient herself was incapable of returning a rational answer. He at length succeeded in discovering the place, where her parents had lived: travelled thither, found them dead, but an uncle surviving; and from him learned, that the patient had been charitably taken by an old Protestant pastor at nine years old, and had remained with him some years, even till the old man’s death. Of this pastor the uncle knew nothing, but that he was a very good man. With great difficulty, and after much search, our young medical philosopher discovered a niece of the pastor’s, who had lived with him as his house-keeper, and had inherited his effects. She remembered the girl; related, that her venerable uncle had been too indulgent, and could not bear to hear the girl scolded; that she was willing to have kept her, but that, after her patron’s death, the girl herself refused to stay. Anxious inquiries were then,
