is the forming a continual regifier, if I may ufe that

after each year, how many would have died out of 
iooo, or one out of how many, or both of them, in 
fubfequent columns, with the differences, increafino-, 
or decreafmg, from year to year. If one only be' 
ufed, I rather prefer the former, as it ffcrikes the eye, 
is a more natural reprefentation of increafing morta- 
lity, and (hews at once, if 1000 were to begin every

year, in proportion to the lives and deaths of fuch 
yeai in the take. The latter may be more agreeable 
to others, and is of fingular ufe towards the end of 
life. I fhall give a ipecimen of both on your table 
for 3 decads, by which you will better perceive what 
I mean, and the ufes (17) that may be made of 
them.
