"A new edition of the "Boy's Playbook of Science" having been called for while the Author was at the antipodes, the publishers intrusted me with the work of revision. My position as Lecturer on Science, and Assistant Superintendent of the Institution with which Professor Pepper's name has so long been associated, has given me the advantage of being able to follow his track more closely perhaps than an outsider could have done. In carrying out my task I have naturally refrained from altering any of the original work, except so far as progress in Science has rendered absolutely necessary."--Reviser's Preface.

Includes "Introduction to the Original Edition.": p. [1]-2.
