The column per mille, ffiould increafe; and that 
one out of, ffiould decreafe, with foine fort of re- 
gularity : I fay no more of thefe, referring to what 
I have written above. My defign here is to ffiew, 
that the term of life (ip) decreafmg too fwiftly, links 
below the truth, and then hands hill, or increaies, 
to become agreeable to the rule of nature, found in the 
courfe of fubfequent years. Thefe irregularities and 
difproportions might be avoided, by beginning with 
43.00 and 68. co; or, it might be as fatisfadlory to 
many, to decreafe the 4.12, years expe&ed to 2.75, 
by proper intervals, or differences, greater above than 
below : an expedient not to be defpifed, when the 
capital points, from and to which, are previoully 
fettled on good » authority. -The term found by 
Dr. Halley’s table is hill wider from the due courle. 
I am apt to imagine, the confcioufnefs of thefe diffi- 
culties induced you to hop ffiort, and perhaps you 
will wonder, that any one elfe would take the pains 
to furmount them. 
But to return. You may poffibly think it unrea- 
sonable, that any body Ihould inhh upon fuch a va- 
riety of fcruples, in a cafe where the beh means of 
information are too lax, and general; yet, I hope, 
will excufe»them, when affured, that my foie reafon 
for infihing upon them, is not a pronenefs to find 
faults, but an earneh (you may call it an over-earneh) 
defire to make what we have better underhood, and 
attain further means of fuch knowlege, and hate 
(19) I ufe this as the fhortcft form, meaning the equal chance, 
or probable expectation of life ; as many furviving, as dying before 
fuch period, among lives of the given age.
