Price of infuring the Life of a Man of and £0. 

 For Example } It being 100 to i, that a Man of 

 2.0 dies not in a Year, and but 38 to 1, for a 

 Man of 50 Years of Age. 



Vfe V. On this depends the Valuation or 

 Annuities upon hives ; for it is plain, that the 

 Purchafer ought to pay for only luch a part of 

 the Value of the Annuity, as he has Chances 

 that he is living ; and this ought to be com- 

 puted yearly, and the Sum of all thofe yearly 

 Values being added together, will amount to 

 the Value of the Annuity for the Life of the 

 Perfon propofed. Now the prefent Value of 

 Money payable after a Term of Years, at any 

 given Rate of Intereir, either may be had 

 from Tables already computed ; or almoft as 

 compendioufly, by the Table of Logarithms : 

 For the Arithmetical Complement of t% Lo- 

 garithm of Unity, and its yearly Intereft, (that 

 is, of 1, 06 for Six pr Cent, being 9, 974^94-) 

 being multiplied by the number of Years pro- 

 pofed, gives the prefent Value of One Pound 

 payable after the end of fo many Years. 

 Then by the foregoing Proportion , it will 

 be as the number of Perfons living after that 

 Term of Years, to the number dead ; Jb are 

 the Odds that any one Perfon is alive or 

 dead. And by confequence, as the Sum of 

 both, or the number of Perfons living of the 

 Age firft propofed, to the number remaining 

 after fo many Years, (both given by the Ta- 

 ble) fo the prefent Value of the yearly Sum 

 payable after the Term propofed, to the Sum 

 which ought to be paid for the Chance the 

 Perfon has to enjoy fuch an Annuity alter io 

 many Years. And this being repeated tor
