Detectives, newspaper reporters, and others who come in contact with many people, usually have this faculty largely developed, for it becomes a necessity of their work, and their interest and attention is rendered active thereby. Public men often have this faculty largely developed by reason of the necessities of their life. It is said that James G. Blaine never forgot the face of anyone whom he had met and conversed with a few moments. This faculty rendered him very popular in political life. In this respect he resembled Henry Clay, who was noted for his memory of faces. It is related of Clay that he once paid a visit of a few hours to a small town in Mississippi, on an electioneering tour. Amidst the throng surrounding him was an old man, with one eye missing. The old fellow pressed forward crying out that he was sure that Henry Clay would remember him. Clay took a sharp look at him and said: "I met you in Kentucky many years ago, did I not?" "Yes," replied the man. "Did you lose your eye since then?" asked Clay. "Yes, several years after," replied the old man. "Turn your face side-ways, so that I can see your profile," said Clay. The man did so. Then Clay smiled, triumphantly, saying: "I've got you now--weren't you on that jury in the Innes case at Frankfort, that I tried in the United States Court over twenty years ago?" "Yes siree!" said the man, "I knowed that ye know me, 'n I told 'em you would." And the crowd gave a whoop, and Clay knew that he was safe in that town and county. Vidocq, the celebrated French detective, is said to have never forgotten a face of a criminal whom he had once seen. A celebrated instance of this power on his part is that of the case of Delafranche the forger who escaped from prison and dwelt in foreign lands for over twenty years. After that time he returned to Paris feeling secure from detection, having become bald, losing an eye, and having his nose badly mutilated. Moreover he disguised himself and wore a beard, in order to still further evade detection. One day Vidocq met him on the street, and recognized him at once, his arrest and return to prison following. Instances of this kind could be multiplied indefinitely, but the student will have had a sufficient acquaintance with persons who possess this faculty developed to a large degree, so that further illustration is scarcely necessary.
