II. On the law of disturbance and the range of the diurnal variation of magnetic declination near the magnetic equator, with reference to the moon’s hour-angle
The discovery by Dr. Lamont of a "decennial” period in the range of the solar diurnal variation of magnetic declination, naturally leads to the question whether a similar law may not exist for the lunar diurnal variation; the question is also of importance in connexion with the theory of the cause of these variations.
