In high altitudes, where nutrition is scant, the birth- rate of boys is high as compared with lower alti- tudes in the same locality. Ploss has pointed out, for instance, that in Saxony from 1847 1° 1849 the yield of rye fell, and the birth-rate of boys rose with the approach of high altitudes. More boys are born in the country than in cities, because city diet is richer, especially in meat; Diising shows that in Prussia the numerical ex- cess of boys is greatest in the country districts, less in the villages, still less in the cities, and least in Berlin.1 In times of war, famine, and migra- tion more boys are born, and more are born also in poor than in well-to-do families. European statistics show that when food-stuffs are high or scarce the number of marriages diminishes, and in consequence a diminished number of births fol- lows, and a heightened percentage of boys; with the recurrence of prosperity and an increased number of marriages and births, the percentage 1 Diising, Das Geschlechtsverhaltniss der Geburten in Preusscn, PP- 29-33. ^ wo crs (X-i \ACA4 , V. jvT'q CVV'M 2'to <xuDpaa a J-yjv-A 4 Co 14 ^cc Ur w\jLf Q £c to Lf-cc^^x. u- (>J• | \ax> L r G, <^> •■'vtF Sck Q-< of$
