This (hews the great Advantage of putting Money 
into the prefent Fund lately granted to their Majefties, 
giving 14 per Cent, per Annum, or at the rate of 7 years 
purchafe for a Life; when young Lives, at the ufual rate 
of Intereft, are worth above 13 years Purchafe. ft 
fhews likewife the Advantage of young Lives over thofe 
in Years a Life of Ten Years being almoft worth 13I 
years purchafe, whereas one of 36 is worth but 11. 
VJe V. Two Lives are likewife valuable by the fame 
Rule ; for the number of Chances of each fingle Life, 
found in the Table, being multiplied together, become 
the Chances of the Two Lives. And alter any certain 
Term of Years, the Product of the two remaining Sums 
is the Chances that both the Perfons are living. The Pro- 
dud: of the two Differences, being the numbers of the 
Dead of both Ages, are the Chances that both the Per- 
fbnsare dead. And the two Products of the remaining 
Sums of the one Age multiplied by thofe dead of the 
other, ffiew theChances that there are thit each Party 
Survives the other : Whence is derived the Rule to efti- 
mafe the value of the Remainder of one Life after an- 
other. Now as the Product of the Two Numbers in 
tire Table for the Two Ages propDfed, is to the diffe- 
rence between that Produd and the Produd: of the 
two numbers of Perfbns deceafed in any fpace of time, 
fois the value of a Sam of Money to be paid after fo 
much time, to the value thereof under the Contingency 
of Mortality. And as the aforefaid Produft of the two 
Numbers anfwering to the Ages propofed, to the Pro- 
dud: of the Decealed of one Age multiplied by thofe 
remaining alive of the other ; So the Value of a Sum of 
Money to be paid after any time propofed, to the value 
of the Chances that the one Party has that be furvives 
the other whofe number of Deceafed you madeufe of, 
in the fecond Term of the proportion. This perhaps
