we have only been able to introduce a few specimens of his drawings; but "The Fairies," "The Antiquary," and others, will give the reader a good idea of Mr. Nasmyth's artistic ability. Since his retirement from business life, at the age of forty-eight, Mr. Nasmyth's principal pursuit has been Astronomy. His Monograph on "The Moon," published in 1874, exhibits his ardent and philosophic love for science in one of its sublimest aspects. His splendid astronomical instruments, for the most part made entirely by his own hands, have enabled him to detect the "willow leaf-shaped" objects which form the structural element of the Sun's luminous surface. The discovery was shortly after verified by Sir John Herschel and other astronomers, and is now a received fact in astronomical science.

A Chronological List of some of Mr. Nasmyth's contrivances and inventions is given at the end of the volume, which shows, so far, what he has been enabled to accomplish during his mechanical career. These begin at a very early age, and were continued for about thirty years of a busy and active life. Very few of them were patented; many of them, though widely adopted, are unacknowledged as his invention. They, nevertheless, did much to advance the mechanical arts, and still continue to do excellent service in the engineering world.

The chapter relating to the origin of the Cuneiform Character, and of the Pyramid or Sun-worship in its relation to Egyptian Architecture, is placed at the end, so as not to interrupt the personal narrative. That chapter, it is believed, will be found very interesting, illustrated, as it is, by Mr. Nasmyth's drawings.
