Excerpt from Elements of Meteorology, Vol. 2: Part II; Meteorological Cycles The regular recurrence of identical physical phenomena is now an admitted fact by all progressive meteorologists but it is difficult to gather their notions as to the character of the cycle, whether it be of definite or indefinite length, and yet more dith cult to ascertain what their ideas are as to its cause, or whether they have any notion whether it is caused at all. It is owing to the latter fact that they have made so little progress in placing Meteorology upon a firm and impregnable basis. It is evident that if it be once accepted as an undeniable truth, that phenomena repeat themselves in periods of a definite length, then the length of the cycle being accurately established, it will become evident that there must be a fixed cause producing this periodicity, and that cause can be discovered. It must be admitted that when such a cause is discovered, its nature and character can be studied and that it can be ascertained under what conditions it manifests itself as cause, and at what time these conditions will recur. Now all that is necessary to enable us to determine Meteorological cycles is to acquire a sufficient knowledge 011 this point. When so much is achieved, we will be able to predict telluric and atmospheric perturbations with as much certainty as we now do eclipses of the Sun and Moon, or the occultations of Jupiter's satellites.
