The remarkable curves which determine the maxima and minima of sunspots, auroral and magnetic phenomena, earth-tremors, earthquakes, barometric, magnetic, and other secular disturbances, have again and again attracted the attention of many skilled observers; and while it is generally admitted that the limits of time and space within which records of such matters have been carefully tabulated are, as yet, too circumscribed to throw light upon many anomalies, it is almost conclusive that the movements of the larger of the planets, notably Jupiter, exercise a very powerful influence mediately or immediately upon the several matters referred to.
It is also noteworthy that the mean death-rate of the Colonies of Australia, for the last twenty years, is lower than the mean death-rate of Europe by about 10 per 1,000 persons living, and that owing to the absence of a dense population the former is comparatively unaffected by those artificial evils attendant upon crowded centres of population.
Includes comparative table showing the suggested coincidence between the death-rate and certain super-terrestrial phenomena.
