On only one subject could Mr. F---- concentrate his thoughts, and that was the law, in the profession of which he obtained considerable success, although occasionally, an awful blunder was committed; but, strange to say, never in the strictly legal part of his doings. He would forget his own name, and write that of some friend of whom he was thinking instead. He would confound plaintiff with defendant, and witnesses with counsel; but he never made a mistake in an abstract legal argument. There, where no collateral, and, as he imagined, immaterial circumstances were concerned--such as, who was the man to be hanged, and who was not--the reasoning was clear, acute, and connected; and for all little infirmities of mind, judges and jurors, who generally knew him well, made due allowance. Other people had to make allowance also; and especially when, between terms, he would go out to pay a morning visit to a friend, Mrs. F---- never counted, with any certainty, upon his return for a month. He would go into the house where his call was to be made, talk for a few minutes, take up a book, and read till dinner time--dine--and lucky if he did not fancy himself in his own house, and take the head of the table. Toward night he might find out his delusion, and the next morning proceed upon his way, borrowing a clean shirt, and leaving his dirty one behind him. Thus it happened, that at the end of a twelvemonth, his wardrobe comprised a vast collection of shirts, of various sorts and patterns, with his own name on very few of them. The stories of poor Jimmy F----'s eccentricities in Edinburgh were innumerable. On one occasion, seeing a lady, on his return home, coming away from his own door, he handed her politely into her carriage, expressing his regret that she had not found Mrs F---- at home. "I am not surprised, my dear," said the lady, who was in reality his own wife, "that you forget me, when you so often forget yourself." "God bless me," cried Jimmy, with the most innocent air in the world. "I was quite sure I had seen you somewhere before; but could not tell where it was."
