II. Application to a Planetary Orbit", read on page): the assumption of identical properties for a body stationary in a gravitational field and one falling under an inverse-square attraction, "previously used to account for optical phenomena", is extended to mass; force equations for gravitational mass m0/(gamma - rdot^2/(c^2 gamma) - r^2 thetadot^2/c^2)^(1/2) are derived, "which when solved for a planetary orbit, give the observed advance of perihelion of Mercury."

Bearing: first statement in this review of what Ives's gravitation theory (claim 4) actually does: a Lorentz-ether style velocity-dependent gravitational mass that reproduces Mercury's perihelion advance. Full text still needed.
