First printing of this important paper which constitutes the original treatments of the Schwarzschild solution of Einstein's gravitational field equations (now known as a black hole), there was an apparent singularity at the Schwarzschild radius (now known as the event horizon). In this paper Eddington introduces a new coordinate system that is non-singular at the event horizon, showing that this is not a true singularity. The coordinates were rediscovered by Finkelstein in 1958.
