SILVER BOOK.
In the Library of Upsal, in Sweden, there is preserved a translation of the Four Gospels, printed with metal types upon violet-colored vellum. The letters are silver, and hence it has received the name of Codex Argenteus. The initial letters are in gold. It is supposed that the whole was printed in the same manner as bookbinders letter the titles of books on the back. It was a very near approach to the discovery of the art of printing; but it is not known how old it is.
