different Tables of Mortality, 357 



35. You will perceive, my dear Sir, that these examples sufficiently 

 establish the accuracy of my method of computing, without imme- 

 diate reference to tables, during the most important portions of life ; 

 and if it be found sufficient, it must be allowed to possess a de- 

 cided superiority, in the facility with which any imaginable change 

 in the value of life is introduced into the computation. This modi- 

 fication is very readily eJBTected by changing the constant quantity 

 c in either mode of computation, or by combining the results ob- 

 tained for any particular case from both methods, in such a man- 

 ner and in such proportions as may be thought most desirable. 

 But it is obvious that, in making these combinations, there must 

 still be ample scope for the exercise of sound judgment and dis- 

 cretion, aided always by personal experience and cautious re- 

 flection. 



I am, my dear Sir, 



Yours most sincerely,

Postscript. The quadratic hypothesis may easily be accommo- 

 dated to any table like my own, of which the decrements are nearly 

 expressed by the mixed formula 368 -f lOx, considering the fluents 

 between the given age and the time of total extinction only: and 

 the same formulas will comprehend the arithmetical hypothesis as 

 a particular case.
