Abstract
THIS interesting volume records the experience of more than 340 million years of life, with nearly three million two hundred thousand deaths, observed in the twenty-five years 1911–35. The industrial policy holders consist mainly of urban populations at the lower level of income, so that their mortality rates would be expected to be somewhat higher than those of the whole population of the same age groups. That is, in fact, the case, but there is clear evidence of convergence, a gratifyingtestimony to the effects of modern sanitary progress. The trends of mortality rates for the very large number of separate causes of death examined are so similar to those of the United States where comparison is possible, that the volume may be taken as a reliable index of the changes of the last twenty-five years.
