Lea & Blanchard have issued, in a beautiful manner, a
handsome book, called 'Philosophy in Sport, made Science in Earnest.'
This is an admirable attempt to illustrate the first principles of
Natural Philosophy, by the aid of the popular toys and sports of
youth. Useful information is conveyed in an easy, graceful, yet
dignified manner, and rendered easy to the simplest understanding. The
book is an admirable one, and must meet with universal favour."--_N.
Y. Evening Mirror._
