THE "Voyages Extraordinaires" of M. Jules Verne deserve to be made widely known in English-speaking countries by means of carefully prepared translations. Witty and ingenious adaptations of the researches and discoveries of modern science to the popular taste, which demands that these should be presented to ordinary readers in the lighter form of cleverly mingled truth and fiction, these books will assuredly be read with profit and delight, especially by English youth. Certainly no writer before M. Jules Verne has been so happy in weaving together in judicious combination severe scientific truth with a charming exercise of playful imagination.
