28. The laws of mortality, such as they were established fifty 

 years ago by the philosophers who were then engaged in their 

 investigation, appear since that period to have undergone the 

 following modifications : 



Mortality of the Different Ages. 



Old State. New State. 



From birth to the age of 10, 50 in 100 38.3 in 100 



50, 74.4 .... 66.0 



60, 82.0 .... 77.0 



Proportion of deaths, - 1 : 32.2 1 : 40.3 



. . . , . births, - 1 : 27-7 1 : 30.1 



marriages, 1 : 110.4 1 : 123.3 



Fecundity, - - - 4.0 4.0 



29. This table, without doubt, contains errors, owing to the 

 incorrectness of several of the accounts given. There is a 

 means, however, of remedying this defect, which would be, 

 that in each country where the laws of its population, and the 

 numbers which express them, are well known, while they are 

 only known through the medium of printing, which too often 

 alters them, some person accustomed to calculations of this de- 

 scription, or even learned societies, would publish accounts si- 

 milar to those which we have given. From these various ele- 

 ments, a general and accurate mean might then be obtained. 



It is with this view that we have published the present note, 

 and that we join to it the state of the population of France 

 in particular, such as it was at the time of Necker in 1780, and 

 such as it is at the present day in 1825, according to the Annuaire 

 du Bureau des Longitudes for the year 1826.
