Chapter VII.— Fertility of Fertile Wives at Different Periods of Married Life. 



With a view to comparison with the results given in Table II., I have prepared 

 the following Table (III.), from the data of St George's-in-the-East, already 

 referred to. The circumstances in which these data were collected, and their pau- 

 city, do not justify me in ascribing to them a value equal to those given in Table 

 II., nor do I think they are well adapted for the purpose of the comparison for 

 which they are adduced. But I know no other to refer to. 



As in the Report of the Committee of the Statistical Society, the periods are 

 counted from the birth of the first child, I have added to them 17 months (l T \ths 

 year), the average interval between marriage and birth of a first child, with a 

 view to make the Table more easily contrasted with Table II.
