From this table it appears, that Mr. Simpson’s approxima- 
tion in the middle ftages of life is fufficiently accurate; but 
that it is exceedingly defective when the life of A is very 
young. It fhould alfo be remembered, that thefe values have 
been computed at a low rate of intereft, and from the 
Northampton Table of Obfervations, in which the decre- 
ments of life come nearer to M. de Moivre’s hypothecs than 
in any other table. But if the computations be made at a 
higher rate of interefl: even from this table, the approxima- 
tion does not always agree fo well, as will appear from the 
following fpecimens calculated at 5 per cent. 
* Thefe values have been computed at 3 per cent, and from the Northampton 
Table of Obfervations.
