I am fenfible you might fay, this is owing to the 
promifcuous changes of y and 6 in the deaths, for 
which you may have reafons, though I cannot fa- 
thom them. With me it is not a matter peculiar to 
your table, but a certain confequence of beginning 
with 1 000 only : for having no changes, but what 
amount to an unit more, or an unit lefs, that is too 
great a leap at once, in fuch fmall numbers j when 
there might have been, in joo and 6 00 deaths, room 
to exprefs duely the intermediate gradations of in- 
creafe, or decreafe, for every tingle year. 
The laft thing I fhall mention, is the term or ex- 
pectation of life, fhortning too fwiftly, and then re- 
coiling. I fhall inftance in your table, and Dr. Hal- 
ley’s too (and the fame will be found in the reft), 
and apply to them his rule above-mentioned, and the 
term, or probable expectation of life, will come out 
thus, for the ages following.
