Abstract of the paper as it appears in American Physical Society's PROLA: "E. Schrödinger; Received 3 September 1926; published in the issue dated December 1926. The paper gives an account of the author's work on a new form of quantum theory. §1. The Hamiltonian analogy between mechanics and optics. §2. The analogy is to be extended to include real "physical" or "undulatory" mechanics instead of mere geometrical mechanics. §3. The significance of wave-length; macro-mechanical and micro-mechanical problems. §4. The wave-equation and its application to the hydrogen atom. §5. The intrinsic reason for the appearance of discrete characteristic frequencies. §6. Other problems; intensity of emitted light. §7. The wave-equation derived from a Hamiltonian variation-principle; generalization to an arbitrary conservative system. §8. The wave-function physically means and determines a continuous distribution of electricity in space, the fluctuations of which determine the radiation by the laws of ordinary electrodynamics. §9. Non-conservative systems. Theory of dispersion and scattering and of the "transitions" between the "stationary states." §10. The question of relativity and the action of a magnetic field. Incompleteness of that part of the theory."

Mehra in the sixth volume of his tremendous The Historical Development of Quantum Theory, volume 6: the Completion of Quantum Mechanics).

We offer the entire volume (1236pp) with the Schroedinger contribution. There are two elegant rubberstamps on the title page--(a) library of the Kaiser-Wilhelm-Institut fuer Physik, and (b) library of the Inst of Spectroscopy at the Max Planck Ges. Institute  $450.00
