最近发现的地球纬度的周期性变化要求我们对地球自转的实际理论进行修正。这种理论是以地球绝对刚性的假设为基础的，它承认存在这种变化，但其规律与观测结果大不相同。该理论给出的地球两极的公转周期约为10个月。观察结果给我们的信息持续了将近14个月。此外，钱德勒先生最近对纬度观测的仔细分析表明，地球两极的运动是由另外两个周期复合而成的，其中一个周期是430天，另一个周期是12个月。
THE recent discovery of periodical variations of terrestrial latitudes demands a revision of the actual theory of the rotation of our planet. This theory, based upon the hypothesis of the absolute rigidity of the earth, admits of variations of this kind, but very different in their laws from those of the observations. The period of revolution of the terrestrial poles given by the theory is one of about ten months. That which the observations give us lasts nearly fourteen months. Still further, the attentive analysis of the observations of the latitudes, executed of late by Mr. Chandler, shows us that the movement of the terrestrial poles is compounded of two others, of which the periods are, the one of 430 days, and the other of twelve months.
