RELATIVE I1SCE.EASE OF MALE BIRTHS IN WAR ' 



In France and otlier countries in early times 106 boys were born 

 to 100 girls, but since 1840, this preponderance of boys has become 

 less. 



Table 30 contains some data as to birth and marriage, previous to, 

 during and after the Franco-Prussian war. In the first line of table is 

 tbe niimber of male births per cent female birtbs showing the tendency 

 in France, as in other countries when at war, to relative increase in 

 the birth of boys, seeming to indicate on the part of nature a tendency 

 to future compensation for the loss of men in the war. Thus the deaths 

 of men relative to that of women in the war time (1870-71, in the se- 

 cond line of table) shows a sudden and great increaoe, as might be 

 expected. 



TABLK 30. — Births and marriages, ])revious, diiring and ofter the war 



The second part of the table shows decrease of marriage during 

 war. Still, births increase and illegitimate births decrease in war. He- 

 re, as in crime, war takes from the commuuity temporarily universal 

 abnormalities to a certain extent, which after the war soon reach or 

 exceed their former rate of increase.
