Dr. Rush mentions a man who imagined that he had a Caffre in his stomach who had got into it at the Cape of Good Hope, and tormented him ever since. Pinel relates the case of an unfortunate man who believed that he had been guillotined, but his innocence having been made complete after his execution, his judges decided that his head should be restored to him, but the person intrusted with this operation had made a mistake, and put on a wrong head. Dr. Conolly knew a man who really believed that he had been hanged, but had been brought to life by galvanism, but he maintained that this operation had not restored the whole of his vitality. Jacobi relates the case of a man confined in the lunatic asylum at Wurtzburg, in other respects rational, of quiet, discreet habits, so that he was employed in the domestic business of the house, but who laboured under the impression that there was a person concealed in his stomach, with whom he held frequent conversations. He often perceived the absurdity of this idea, and grieved in acknowledging and reflecting that he was under the influence of so groundless a persuasion, but he never could get rid of it. "It was very curious to observe," adds our intelligent author, "how, when he had but an instant before cried what nonsense!--is it not intolerable to be thus deluded? and while the tears which accompanied these exclamations were yet in his eyes, he again began to talk, apparently with entire conviction about the person in his belly who told him that he was to marry a great princess. An attempt was made to cure him, by putting a large blister on his abdomen, and the instant that it was dressed, moving from behind him a dressed-up figure, as if just extracted from his body. The experiment so far succeeded that the patient believed in the performance, and his joy was at first boundless in the full persuasion that he was cured; but some morbid feeling about the bowels, which he had associated with the insane impression, still continuing, or being again experienced, he took up the idea that another person similar to the first was still left within him, and under that persuasion he still continues to labour." A nobleman of the court of Louis XIV., fancied himself a dog, and would invariably put his head out of window to bark aloud. Don Calmet relates the case of some nuns in a convent in Germany, who imagined that they were transformed into cats, and wandered about the building loudly mewing and spitting at and scratching each other.
