1) As I have often stated, Laplace anticipated Gauss by some 40 years. In his memoir of 1783, Histoire de I'Acadimie, pp. 423-467, he gives the expression for the probability integral and suggests* (p. 433) its tabulation as a useful task. It is clear that to do this is to recognise the -existence of the probability-curve or in its doubly projected form Laplace's investigation while not proceeding from the very simple axioms .of Gauss, which lead directly to the above equation, is more

It has led many writers to try and force all frequency by aid of one or another process of distortion into a ' normal' curve. Gauss starting with a normal the law of distribution of errors reached at once the method of least squares. To understand the origin of the correlational calculus we must really go back to Gauss' fundamental memoirs on least squares, namely the Theoria combinationis obtervcUionum errortbus minimit obnoxiae of 1823 and the Shipplemmtum of 1826.
