IT is imposible to read Dr. Hobson's book without reflecting on the marvellous change that has come over Cambridge mathematics in the last twenty years. Twenty years ago Cambridge mathematics was a thing standing by itself, and with its own virtues and defects. Pure mathematics in Cambridge meant Cayley and a few disciples; and Cayley (widely as he read) owed little or nothing to anyone but himself. Certainly he never appreciated the most fundamental ideas of modern Continental analysis. It is probable that he could not have defined a function or a limit in a way which would have satisfied Weier-strass or Dr. Hobson: it is certain that he would have been as incapable as any Senior Wrangler of proving any of the less obvious theorems of convergence. The first signs of the absorption of these ideas are td be found, not in Cayley, but in Stokes. The Theory of Functions of a Real Variable and the Theory of Fourier's Series. By Dr. E. W. Hobson Pp. xvi + 772. (Cambridge: University Press, 1907.) Price 21s. net.

Our previous principal component analysis conducting on reference points, lines and angles, and a vector-developed polar coordinate system has elucidated that the components of eigenvectors had positive relationships in the curvature of anterior teeth segment, between the protrusion of canines and degree of arch roundness, and in the length-to-width ratio of 62 maxillary dentitions, which were preliminarily classified with reference to the conventional Thompson’s morphological descriptions for dental arch forms. In the present study on morphological characters of the maxillary dentitions, we conducted a Fourier analysis on the previously obtained data. We observed that the amplitude of 2 nd , 3 rd and 4 th Fourier harmonics were closely correlated with the length-to-width ratio, curvature of the anterior teeth segment, and the curvilinear contour of maxillary dental arches. In addition, the relationships between previously estimated data and the constant value and the amplitude of the Fourier series were examined by analysis of correlation coefficients(p＜0.01). The results of the present study suggest that the morphology of maxillary dentitions consists of three essentials-the length-to-width ratio, the curvature of anterior teeth and the curvilinear contour of dental arches.
