232 Fig. 6.—R. Antero-lateral and R. Dentary. r = 0*80

Dotted line is the r line inclined to axis x at tan”"1 0*80. The continuous line joining the crosses is the line found on taking the R. anfcero-lat. as subject. The circles indicate the points obtained when the R. dentary is the subject. The probable errors of the dimensions are represented by intervals, 1, 2, 3, &c., on both horizontal and vertical scales.

taking one dimension as the subject and the other as the relative, then for every unit of deviation of the subject the mean of the associated values of the relative was found. The values of the subject and the associated mean values of the relative are expressed in terms of their probable errors, and plotted along the axes of y and x respectively. The points indicated by circles were obtained by reversing the positions of subject and relative.

It is clear that the crosses and circles do tend to lie along a line
