DEATH strikes from every side, but not at random. The varying force of its blows, according to the age of its victims, has at all times been remarked. Some fifteen years ago Professor Karl Pearson suggested that death might be imagined as at work in five successive stages, corresponding to five ages of life, and armed with weapons the energy and precision of which varied for each of the ages. He thus substituted for the antique scythe more modern weapons, although the dread reaper has not as yet abandoned the blade which, in circumstances happily now of rare occurrence, levels all before it.Setting aside these exceptional circumstances, and the influence of advancing age, and ignoring individual differences, we should even yet not find groups of human beings, thougb of equal age, whose chances were equal before the risks of death. Such groups vary according to time and place and according to race, occupation, style of living, &c. It is necessary to measure these changes if one wishes to estimate correctly the importance of the factors of mortality. The organisation of insurance, biological studies, public hygiene, the vitality of the race are all concerned with a precise knowledge of the action of these factors. Many statistical data have already been secured, the significance of which it is desirable to examine closely. I propose to deal with some of the more recent investigations.
