Text: "Discussion of a kinetic theory of gravitation, IV: Correlation of continual generation of heat in some substances, and impairment of their gravitational acceleration." An experiment that shows that aluminum silicate falls slower than other materials. Such further confirmation has since been documented by the Stardust Project furthering the research and experiments of falls by Lloyd B. Zirbes, which has been videotaped. American Philosophical Society. Proceedings. 67(1), 1928. p. 105-117.
