² More exact tests, based upon the standard deviation, may be performed upon a group of crania to determine the homogeneity of its composition. Thestandard deviation is likewise the basis for all determinations of the likeness or unlikeness of two series.

⁴ In order to have the benefit of the largest possible number of skulls, Morant included in his Neolithic series a number of crania resembling theNeolithic physical type, but of Bronze Age date. These he selected from the Bronze Age material by a mathematical process for which the reader must be referred to the original paper. Whilethe author agrees entirely with Morant that such individuals of the Neolithic race were present in the Bronze Age, he feels that the method by which they were segregated by Morant may haveaffected his total ‘British Neolithic’ series, in which they were incorporated ;i.e., the variability of the latter may have been artificially reduced, and it is possible thtthe average figures for basion-bregma height and bizygomatic breadth are too high and too low respectively. There is therefore the greatest needfor sufficient crania of unquestioned Neolithic date.

⁵ Archaeological opinion doubts that the Beaker People actually introduced bronze into Britain, but in dealing with physical form the terms ‘Beaker People’ and ‘Bronze Age type’ may be used synonymously.
