The series is designed to bring within popular comprehension the various operations and procedures in Science and the Arts, the phenomena and laws of nature, curious and striking facts in natural history, remarkable exploits, archæological discoveries, and a historical account of the progress of the fine arts. The subjects treated are of universal interest, and they are discussed in a popular and interesting manner.

The illustrations are very numerous, and leave nothing to be desired on the score of completeness; they add materially to the attractiveness and value of the series, which is by far the most thorough, interesting, and valuable of the kind ever produced.
