We have carefully reexamined the results of the experiment of E\"otv\"os, Pek\'ar, and Fekete, which compared the accelerations of various materials to the Earth. We find that the E\"otv\"os-Pek\'ar-Fekete data are sensitive to the composition of the materials used, and that their results support the existence of an intermediate-range coupling to baryon number or hypercharge.
Fischbach et al. (Mon,) studied this question.
