416, we have one marriage per 263 inhabitants. In England 

 the ratio is 1 per 134. The number of marriages being 632 the 

 year preceding the census, we have 3*96 per 1,000. 



Mortality. — This is a subject of the greatest importance, 

 and for the analyses of which we fortunately possess correct and 

 precise data.

Table showing number of deaths for ten years (1870 to 1879): 



Adding the totals of the two periods (sixteen years), we have 

 52,700 deaths, or a yearly average of 3,293*75; 2,318 in the 

 first period, and 3,879 in the second period. If we take the 

 mortality in 1871 (the year of the census), we have one death in 

 30*73 inhabitants, or again 30*73 per 1,000. If I omit the mor- 

 tality of the year 1872, during which a most severe epidemic of 

 small-pox prevailed, we have for the nine years an average of 

 3,615 deaths. If we take the mortality in 1880 (the year pre- 

 ceding the census), we have the proportion of 2*55 per cent.
