Abstract
AT the present moment the answer to the question as to whether the rate of rotation of the earth is fluctuating, depends almost wholly on the interpretation which shall be given to certain differences between the observed positions of two or three bodies in the solar system andtheir positions as calculated from the laws of motion and gravitation. Owing to the unavoidable errors of observation, usually greater in the past than now, a detailed discussion of the astronomical data is necessary in order to discover, if possible, the extent to which the astronomical evidence is reliable. To me it has appeared to be sufficiently good to warrant full consideration of its consequences and to suggest further search for confirmation of the results.
