Smithsonian Scientific Series Great Inventions By Charles Greeley Abbot PDF Download

Excerpt from Great Inventions With this volume the Smithsonian Scientific Series is completed. It has cost more of efi'ort on the part of the Smithsonian Institution than was anticipated. An exact ing standard of accuracy and interest in text and illustra tions has required more time than was expected for the preparation of the books. It is my hope that the quality of the finished product may be found to justify the long delay in completion. As Secretary of the Smithsonian Institution, I wish to thank the subscribers for the interest which they have evinced in its work and welfare. As a direct result of this interest, a large sum has already been added through royalties from sales of the Series, to the resources of the Institution, for the furtherance of its scientific investi gations.
