It is of no little importance in dynamic studies to keep ever in mind that the earth's sphere of control not only revolves within the sphere of control of the sun, but that its position is deep within it. The sun's sphere of control extends at least several hundred times as far beyond the earth as the earth is from the sun. Its precise extent has not been deter- mined ; indeed, is not determinable at present, from lack of sufficient data respecting competitive attractions outside. I have, however, en- deavored to reach an approximate notion of its extent by projecting graphically certain dynamic indications of its extent found in the outer planets. These imply that the radius of the sphere of control of the sun.
