HOW POPULATION INCREASES 53 Hwa-Luh for China’s population, the successive value in millions in the two cases are as shown hereunder: — Correspondence in the Modes of Population-Increase Date- seyear for} yyrs a73s 1755 1775 1795 1815 183s Date-year for Ruocane, cit. } 1800 1820 1840 1860 1880 1900 1920 Populati opulationof 1 133 x54 187 235 288 348 do Population of Bon or) 137 ¥62 196 232 280 347 419 If we reduce the population figures for Europe, etc., so as to make the two aggregates equal for the 120 years covered, it gives a better comparison of form. The bottom figures would then be: 135, 160, 193, 229, 276, 342, and 413. The present population of China is probably 468 millions, to which it had nearly attained in 1870 (436 millions): its increase had markedly dimished over half a century ago. The above figures show that the population of the western world is revealing something of the same characteristics, in respect of the changes in the rate of increase, that China did about 85 years earlier. This is a striking fact and obviously cannot be ignored by the student of the mode of population- increase. Long ago a much more limited survey of such changes of increase as have just been illustrated, suggested to a Belgian, Verhulst, that any country may be regarded as a sort of totality, analogous in its nature to a restricted region populated by organisms, the mere multiplication of which was continually and increasingly limiting the possibility of their further increase in number. The simplest mode of expressing this idea, is to assume that the group of organisms tend to reproduce themselves, continually reacting to a
