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).
