And accordingly, if,/*, be = ioo, and c—6* 

 (the number of Pounds that an ioo/.'put out 

 to Intereft, brings in at the Year's end;) and 

 confequently my Share of Certainty from One 

 •Reporter, be =r§i % which is the prefent va- 

 lue of any Summ to be paid a Year hence : The 

 Proportion of Certainty coming to me from a 

 Second, will be r|| multipiyed by To° 6 (which 

 -is the prefent Value of Mony to be paid after 

 two Years^) and that from a Third-hand Re- 

 porter, r=f i^z : thrice multiplied into it felf ; 

 (the Value of Mony payable at the end of 

 Three Years) &c. 



Corollary. 



And therefore, as at the Rate of 6 per Cent. 

 Interefr, the prefent Value of any Summ pay- 

 able after Twelve Years, is but half the Summ 

 So if the Probability or proportion of Certi- 

 tude tranfmitted by each Reporter, be ; 

 the Proportion of Certainty after Twelve fuch 

 TranfmiiTions, will be but as a half ; and it will 

 grow by that Time an equal Lay, whether the 

 Report be true or no. In the fame manner, if 

 the Proportion of Certainty be fet at \|? lt 

 will come to half from the 70th Hand : And if 

 at \HU from the 695th.
