## The Gravitational Field

The law governing the properties of the gravitational ﬁeld in space must be a perfectly deﬁnite one, in order correctly to represent the diminution of gravitational action with the distance from operative bodies. It is something like this: The body (e.g. the earth) produces a ﬁeld in its immediate neighbourhood directly; the intensity and direction of the ﬁeld at points farther removed from the body are thence determined by the law which governs the properties in space of the gravitational ﬁelds themselves.
