" Now, by the investigations made under the di- 

 rection of the Comte de Chabrol, the average of births 

 to a marriage is, in the different arrondissements, in 

 regular inverse proportion to the easy or opulent cir- 

 cumstances of the population. In the first four ar- 

 rondissements united, which are those where the most 

 opulent families reside, the number of children to a 

 marriage is only 1.97 ; that of the four poorest arron- 

 dissements, on the contrary, is 2.86; and the differ- 

 ence between the two arrondissements placed at the 

 extremities of the scale is as 1.87 to 3.23, or more 

 than 73 per cent. 



" These facts deserve the more attention because, in 

 spite of the reasons which determine the inhabitants 

 of Paris to choose peculiar localities, according to their 

 respective circumstances, some poor families will be 

 found in the quarters inhabited by the rich, and some 

 rich families in the quarters occupied by the poor ; 

 which fact necessarily diminishes the difference we 

 should establish if it were possible to separate com- 

 pletely the different classes of the population. We 

 arrive at this important consideration that, if the 

 second, third, tenth, and first arrondissements, where 

 the richest families in Paris reside, were not continu- 

 ally recruited from families freshly acquiring wealth, 

 the actual number of inhabitants would not be main- 

 tained. Not only the children born there are less 

 numerous than their parents, but, as we must deduct 

 those who die in infancy, or who never marry and 

 that we must estimate these at least at a quarter of
