First Edition (NAP, 1936 on the title page). Very nice looking book. You can see the covers in the photos. There's a little whitish soiling on the spine The gilt lettering on the spine is very bright. There is just a little bit of crinkling the top edge of the spine. The cover edges are in excellent shape. The cover corners look very good. The page edges look very clean. The book is square and the spine is straight. The book is very solidly bound from cover to cover with nicely tight pages throughout and nicely tight covers as well. The pages are in excellent condition. They are very clean. Scrolling through, I'm not seeing any soiling. I'm not finding any creasing, no turned-down corners or placeholder creases. There are no markings. No attachments of any kind (which means NOT ex-library). There is only one instance of writing: on the rear cover a previous owner has very neatly printed his name and address in Peoria, Illinois.

Book Description Hardcover. Condition: Very Good. 1st Edition. vi, 1 leaf, 336 pp. Original cloth. Top fore edge foxed. Very Good. This copy does NOT have any library markings. First Edition, American issue. "His technical book The Relativity Theory of Protons and Electrons (1936), based almost wholly on the spin extension of relativity, spurred Eddington to evolve a statistical extension. Thus during his last years he worked indomitably toward his dream--'Bottom's dream'--he called it--his vision of a harmonization of quantum physics and relativity. The difficulties were immense, and, as we now know, the greatest complexities of nuclear physics and subatomic particles were not yet discovered. But he took hurdle after hurdle as he saw them, with daring leaps, always landing, as he believed, surefootedly on the far side, even though he could not demonstrate his trajectories with mathematical rigor" (D.S.B. 4: 281-82).
