Isakson Leningrad, 21 March 1926 In their study of Einstein 1925t (Doc. 17) the question arose as to whether one can in- troduce tensors that distinguish an “over-Riemannian” geometry, first introduced by J. Schouten, from a Riemannian geometry. The postulate introduced by AE, which is in- dependent of the variation principle, may be a solution to the fundamental equations in
