The historical case of the unnamed Dutchman is known to all students of memory. This man is said to have been able to take up a fresh newspaper; to read it all through, including the advertisements; and then to repeat its contents, word for word, from beginning to end. On one occasion he is said to have heaped wonder upon wonder, by repeating the contents of the paper backward, beginning with the last word and ending with the first. Lyon, the English actor, is said to have duplicated this feat, using a large London paper and including the market quotations, reports of the debates in Parliament, the railroad time-tables and the advertisements. A London waiter is said to have performed a similar feat, on a wager, he memorizing and correctly repeating the contents of an eight-page paper. One of the most remarkable instances of extraordinary memory known to history is that of the child Christian Meinecken. When less than four years of age he could repeat the entire Bible; two hundred hymns; five thousand Latin words; and much ecclesiastical history, theory, dogmas, arguments; and an encyclopedic quantity of theological literature. He ia said to have practically retained every word that was read to him. His case was abnormal, and he died at an early age.

John Stuart Mill is said to have acquired a fair knowledge of Greek, at the age of three years, and to have memorized Hume, Gibbon, and other historians, at the age of eight, shortly after he mastered and memorized Herodotus, Xenophon, some of Socrates, and six of Plato's "Dialogues." Richard Porson is said to have memorized the entire text of Homer, Horace, Cicero, Virgil, Livy, Shakespeare, Milton, and Gibbon. He is said to have been able to memorize any ordinary novel at one careful reading; and to have several times performed the feat of memorizing the entire contents of some English monthly review. De Rossi was able to perform the feat of repeating a hundred lines from any of the four great Italian poets, provided he was given a line at random from their works—his hundred lines following immediately after the given line. Of course this feat required the memorizing of the entire works of those poets, and the ability to take up the repetition from any given point, the latter feature being as remarkable as the former. There have been cases of printers being able to repeat, word for word, books of which they had set the type. Professor Lawson was able to teach his classes on the Scriptures without referring to the book. He claimed that if the entire stock of Bibles were to be destroyed, he could restore the book entire, from his memory.
