In confirmation of the conserved vector current (CVC) hypothesis, the vector coupling coupling constant is demonstrated to be constant to better than 3 parts in 10^4, and any induced scalar current is limited to fs \\leq 0.0013 in electron rest-mass units. The possible existence of a fundamental scalar current is similarly limited to |Cs/Cv| \\leq 0.0013. The superallowed data also determine the CKM matrix element to be Vud = 0.9738(4).
