In London, for some years past--how many is not stated--about 240 persons annually have made away with themselves--sometimes a few more, sometimes a few less--the highest number having been 266 in 1846, and the lowest 213 in 1849. But, while the number of suicides has thus been nearly stationary, population has been anything but stationary in the metropolitan district, but has advanced with vast and unremitting strides at an average rate of nearly 43,000 a year. In 1841 it was 1,948,369; in 1851, 2,361,640; and in 1861, 2,803,989. The proportion of suicide to population has consequently been by no means uniform, but has varied exceedingly, and on the whole has shown a constant tendency to decrease. But even if it had continued uniform, it would simply have shown that, during a certain number of years, the general character of Londoners had, in certain particulars, undergone no material change. It would not have proved that the regularity of suicide observable among Londoners was in accordance with any general law. To prove this it would have been necessary to show that the proportion had been uniform, not only in the same but in all societies; in Paris as well as in London, among the Esquimaux of Labrador, and among the Negroes of Soudan. For, if the proportion were found to vary by reason of the differing circumstances of different societies, it would plainly be seen to be at least susceptible of variation in the same society, inasmuch as in no society do circumstances remain the same from generation to generation. So equally with murders. Even if there were no doubt that the percentage of such crimes in England had long continued the same, still that fact would prove nothing as to the uniform reproduction of crime, if it could be shown that the percentage had ever varied anywhere else--in France or Italy, for example, or in Dahomey. For it would be mere childishness to point to the different conditions of England and Dahomey, and to plead that no more was intended to be said than that, with uniformity of circumstances there would also be uniformity of results. So much no one, in the least competent to discuss the subject, would for a moment dream of disputing. But in political affairs there cannot be uniformity of circumstances. The aggregate of circumstances from which spring human motives cannot, from the nature of things, ever be repeated; and, though a few general causes may continue permanently in operation, they cannot continue to produce the same identical results; for even though they could themselves remain stationary, it would be impossible that their operation should not be affected by the constant change going on around, or should not partake of an otherwise universal forward movement. In political affairs there cannot possibly be any recurrence of identical phenomena; nor can there, except within a very limited period, be any occurrence of very similar phenomena. But recurrence (and not merely
