computation of logarithms. 249 



Example 5. 



Because 2^ zr 8, therefore 

 Logarithm 2 •3010299954- 

 Muhiplied by 3 3 



Gives Logarithm 8 -903039987. 



ExATvlPLE 6. 



Because 3^ z;i 9, therefore 

 Logarithm 3 •477121254-;;^- 

 Multiplied by 2 ^ 



Gives logarithm 9 -954242509. 



Example 7. 



Because "-^ n: 5, therefore 

 Prom logarithm 10 1*000000000 

 Take logaritlmi 2 -301029995-^- 



Reniains logarithm 5 •698970004J 



Example 8. 



Because 3X4:= 12, therefore 



To logarithm 3 -477121255 



Add logarithm 4 602059991 



Sum is logarithm 12 1*079101246. 



And thus, computing by this general ruk, the logar- 

 ithms to the other prime numbers 7, II, 13, 17, 19, 23, 

 $ic, and then using composition and division, \rc may ea-
