Memory
the gist of the thing was in taking an interest in names in general. In this way an uninteresting subject was made interesting—and a man always has a good memory for the things in which he is interested.
The case of Mr. X. is an extreme one—and the results obtained were beyond the ordinary. But if you will take a leaf from his book, you may obtain the same results in the degree that you work for it. Make a study of names—start a collection—and you will have no trouble in developing a memory for them. This is the whole thing in a nut-shell.
