A fine fresh example (small pencil mark to upper wrapper) of THIS RARE PAPER!! - ."Although Einstein could not accept Weyl's theory as a physical theory, he cherished "its courageous mathematical construction" and thought intensively about its conceptual foundation. This becomes clear from his paper "On a complement at hand of the bases of general relativity" of 1921. In it, he raised the question whether it would be possible to generate a geometry just from the conformal invariance of Equation without use of the conception "distance", i.e., without using rulers and clocks. He then embarked on conformal invariants and tensors of gauge-weight 0, and gave the one formed from the square of Weyl's conformal curvature tensor" Hubert, F.M.
