Abstract
A RECENT paper by Einstein and Bargmann1 declared that "Ever since the theory of general relativity has been developed there has existed the problem of finding a unified theory of the physical field by some generalization of the relativistic theory of gravitation ... a decisive modification of the fundamental concepts is unavoidable". Schrödinger2 has also explained the need for a generalization of Einstein's original postulates in order to unify the theories of gravitation, electromagnetism, and the mesonic field responsible for binding the nucleus. There is no danger of the work of Einstein and Schrödinger being overlooked, but there is great danger that what is apparently an investigation of great importance, namely, "The Theory of Indeterminate Space-Time", by F. R. Saxby, may be missed by physicists, as it appears not in any of the usual scientific journals, but in the Bulletin of the Research Laboratories of the National Cash Register Company (pp. 13–72, September 1943), of which laboratories he is mathematics staff engineer.
