    wittout supposing sometlaing of the same kind to occur; and I suppose that nobody will accept the idea as possible. The third sub-case remains^ namely that the power is always existing around the sun and through infinite space^ whether secondary bodies be there to be acted upon by gravitation or not; and not only around the sun^ but around every particle of matter which has existence. This case of a constant necessary condition to action in space^ when as respects the sun the earth is not in place, and of a certain gravitating action as the result of that previous condition when the earth is in placCj I can conceive, consistently, as I think, with the conservation of force: and I think the case is that which Newton looked at in gravity; is, in philosophical respect, the same as that admitted by all in regard to light, heat, and radiant phsenomena; and (in a sense even more general and extensive) is that now driven upon our attention in an espe- cially forcible and instructive manner, by the phsenomena of electricity and magnetism, because of their dependence on dual forms of power.
