508 Effects of Epidemics on Registei^s of Bk. ii. 



to 10 and 35 to 10, and the mean about 37 to 10. 

 In this table no very great epidemics occur till 

 the 3 years beginning with 1757, and beyond this 

 period the lists are not continued. 



In the dukedom of Pomerania, * the average 

 proportion of births to deaths for 60 years (from 

 1694 to 1756 both included) was 138 to 100 ; but 

 in some of the periods of six years it was as high 

 as 177 to 100, and 155 to 100. In others it sunk 

 as low as 124 to 100, and 130 to 100. The ex- 

 tremes in the proportions of births to marriages 

 of the different periods of 5 and 6 years, were 36 

 to 10 and 43 to 10, and the mean of the 60 years 

 about 38 to 10. Epidemic years appear to have 

 occurred occasionally, in three of which the deaths 

 exceeded the births ; but this temporary diminu- 

 tion of population produced no corresponding 

 diminution of births, and the two individual years 

 which contain the greatest proportion of marriages 

 in the whole table occur, one in the year after, and 

 the other two years after epidemics. The excess 

 of deaths however was not great till the three 

 years ending with 1759, with which the table 

 concludes. 



In the Neumark of Brandenburgh, f for 60 

 years, from 1695 to 1756 both included, the ave- 

 rage proportion of births to deaths in the first 30 

 years was 148 to 100, in the last 30 years 127 to 

 100, in the whole 60 years 136 to 100. In some
