✦ Synopsis

It is a characteristic of the new field theory that if the above equations form a satisfactory solution, then another satisfactory solution is g; f;;(kxi, kxs, kx&, kx4) (k=constant), g; = fi;(kxi, kxs, kxr, kx4) (k=constant), V' representing a different physical reality. In addition, if g;; and g;; satisfy certain conditions which Einstein gives for free space at (xl xr x3 x4), then g; and g; satisfy the conditions at V' (kxI, kx2, kx3, kx4).

Consequently, in the new solution, as in the original one, there are three, isolated, non-free-space, space-time regions, representing three material bodies in motion. Taking the three coordinates xI, x2, and x3 as ordinary Cartesian spatial coordinates and x4 as the
