Interpolation as a means of approximation to the gamma function for 

 high values of h\ R. Pearl (Science, n. ser., Jfl {1915), No. 1057, pp. 506, 

 507). — A series of computations is reported, from which it is concluded that 

 " the interpolation method, when third differences are used, gives values slightly 

 better than those by Forsyth's method" when h>2.5. For «=75 or more the 

 interpolation method using only second differences gives an approximation suf- 

 ficiently close for all practical statistical purposes. As to the labor involveil, 

 there is no great amount of choice between Forsyth's and the interpolation 

 method, but on the whole there appears to be a distinct, if small, advantage in 

 favor of the interpolation."
