inflation of the Gaussian point, G, to cover all that may be happening in the whole 
area of possible /3 1} /3 a points in our diagram. It cannot at present be too often

indicated,* the assumption that the distribution curves of statistical constants follow 
the Gaussian curve is not legitimate, especially in the case of “small samples,” which 
not only for many commercial purposes, e.g., experimental brewing, but in numerous 
branches of science, e.g., psychology, astronomy, and even physics, are all that 
economy of money or time permits of being recorded.
