Thus it took some time to learn that volcanic eruptions occurred with a very fair degree of regularity. In judging of this and all other rhythmical events it must be borne m mind that the time standard is for an irregularity that seems large, as- in the instance just referred to, becomes small when considered in relation i» the millions of yean of geological time; while in the case of music a trifling irregu- larity, judged by fractions of a second, can not be tolerated by the musical organization—^which is equivalent to saying that the interval of departure from exact regularity seems large. As most of the rhythms of the universe are compounded of several, it follows that they may seem, until closely studied, very far from regfular recurrences. This may be observed in the interference in the regularity of the tides themselves, the daily changes of which are subject to an increase and decrease twice in each month, owing to the influence of the sun and moon being then either coincident or antagonistic. In the functions of plants and animals, rhythms must be- come very greatly compounded,
