Sussmilch. He quotes Busching, who states the 

 mortality of the whole Prussian monarchy to be 1 

 in 30.* But it appears that this inference was drawn 

 from lists for only three years, a period much too 

 short to determine any general average. This pro- 

 portion, for the Prussian monarchy, is indeed com- 

 pletely contradicted by subsequent observations 

 mentioned by Crome. According to lists for five 

 years, ending in 1784, the mortality was only 1 

 in 37. f During the same periods, the births were 

 to the deaths as 131 to 100. In Silesia the mor- 

 tality from 1781 to 1784 was 1 in 30; and the 

 births to deaths as 128 to 100. In Gelderland the 

 mortality from 1776 to 1781 was 1 in 27, and the 

 births 1 in 26. These are the two provinces of 

 the monarchy, in which the mortality is the 

 greatest. In some others it is very small. From 

 1781 to 1784 the average mortality in Neufchatel 

 and Ballengin was only 1 in 44, and the births 1 

 in 31. In the principality of Halberstadtz, from 

 1778 to 1784, the mortality was still less, being- 

 only 1 in 45 or 46, and the proportion of births to 

 deaths 137 to 100. J 



The general conclusion which Crome draws is, 

 that the states of Europe may be divided into 

 three classes, to which a different measure of 

 mortality ought to be applied. In the richest and 

 most populous states, where the inhabitants of 

 the towns are to the inhabitants of the country in
