LV] Introduction Ixxxiii 



</> = 8-4386, r = 31: 



log H(r, v) = -388,5583 + (-4386) [238] - (-4386) (-5614) [27] 



= "388,5684. 

 <f> = 8-4386, r=32: 



log H (r, v ) = -388,8910 + ('4386) [231] - } (-4386) (-5614) [26] 



= -388,9008. 

 Hence <f> = 8H386, r = 30 8023 : 



log H (r, v ) = -388,2137 + -8023 [3547] - (-8023) (1977) [- 223] 



= -388-5001. 

 Hence by formula (Ixxxv) : 



log F (r, v) = v<f> log e + r+ I log cos <j> - \ log (-!) + log H (r, v). 

 Or, using Tables LIII and LV, we have 



logF(r, v)= -292,2901 - -737,1249 

 + 1-849,6578 

 + -388,5001 



.-..{0,4480 

 - -737,1249 



\ogF(r, i/)- 1-798.8231 

 Finally from formula (xci) : 



log y = log N - log a - 1-793,3231 



= 3-340,8405 -1-175,8509 



-1793,3231 



969,1740 

 = 2-371,76665. 



Or y = 235-324*. 



TABLE LV. 



This table contains some miscellaneous constants in frequent statistical or 

 biometric use and requires no illustration. It has already been used in the 

 illustrations to previous tables. 



I have had the generous assistance of my colleagues Miss E. M. Elderton and 

 Mr H. E. Soper in the preparation of the Illustrations to these Tables. I can 

 hardly hope that arithmetical slips have wholly escaped us in a first edition, 

 and I shall be grateful for the communication of any corrections that my readers 

 may discover are necessary. 



* The value 235-323 obtained in Phil. Trant. Vol. 186, A, p. 387, was found by the approximate 

 formula (xciv) before tables were calculated.
