Reprint of the original, first published in 1875.

This book describes the fundamental aspects of materials characterization for the ferric oxyhydroxides formed on steel surfaces. Selected examples, from both the basic science and the applied engineering points of view, are presented. Of special interest is the new structural information on ferric oxyhydroxides containing a small amount of alloying elements. The text relates this to their various states and their role in corrosion processes.

Excerpt from Looking Skyward and the Earth: Illustrated Though technicalities are absolutely necessary in the fuller understanding of astronomy, I have avoided the more intricate parts and endeavored to frame my explanations in ordinary language so that all classes of readers can understand. So to reach the masses is my chief object, - my apology - and to be of aid even to the mathematician or professor, not an impediment. Though my helps, in proper instruments, etc., etc., are very limited, pains have been taken to avoid errors. Yet they will be found. Perfection is not attained at a bound.
