94 Mr. Hellins's Second Appendix to the improved 

 First, for the value of A. 



Numbers. Logarithms. Numbers.* 



Here a = 1-5236,71 "\ 0-1828,913 



and b = 1-44,51,60 J Ar.co. 1-8400,841 

 a — b = 0-0785,11 2-8949,305 



a + & = 2-9688,31 0-4725,855

Sum of these two logarithms 5-920 - — o 00008 = — gc 4 



— 0-00395 = — ice — gc* 

 The sum of these four terms is - - 75,81761. 



Having now found the value of the four terms - — \- e — fee 

 — gc 4 , we must next find the value of the three logarithmic 

 terms a -f J- ace -|- -^a^ 4 , or a -|- b -j- c = S, which may 



quickly and easily be done as fellows. 



The common logarithm of 2 is 030 10,300 

 Half the common logarithm of cc is 1-2111,725 



The common logarithm of— is 1 0898,575; and this lo 

 garithm, reduced to an hyperbolic logarithm, by Table XXXVII.
