It is to be observed that the statements, in the above table, 
with regard to the cities of Naples and Vienna, and the diocesses 
of Bergen and Christiana, in Norway, are given for only a single 
year. The period is, therefore, too short, and the result deduced 
from too small a number of deaths to be safely considered as the 
general average. ‘The statement with regard to New Hampshire is 
the result of calculations which have already been explained : that - 
respecting Philadelphia is formed on the bills of mortality for 10 
years, ending with the year 1816, as given in the Transactions of 
the American Philosophical Society : that with respect to Sweden 
from official returns for 9 years, ending with 1763: that respect- 
ing Russia from official returns of deaths of persons belonging to 
the Greek church, in that empire, during the years 1801, 1813, 
and 1820: that with regard to London from the bills of mortality 
during 38 years, ending with 1820. 
From a comparison of the above results, it appears that New 
Hampshire furnishes a greater proportion of centenarians than 
Sweden or Russia, both of which countries are distinguished for
