THEORY OF STATISTICS. the distribution, in such a way as to suggest that the ideal curve is tangential to the base. Cases of greater asymmetry, suggesting an ideal curve that meets the base (at one end) at a finite angle, even a right angle, asin fig. 9 (8), are less frequent, but occur occasionally. The distribution of deaths from diphtheria, according to age, affords one such example of a more asymmetrical kind. The actual figures for this case are given in Table XIL., and illustrated by fig. 14 ; and it will be seen that the frequency of deaths reaches a maximum for children aged “3 and under 4,” the number rising very rapidly to the maximum, and thence falling so slowly that there is still an appreciable frequency for persons over 60 or 70 years of age.

The extremely asymmetrical, or J-shaped,” distribution, the class-frequencies running up to a maximum at one end of the range, as in fig. 15. This may be regarded as the extreme form of the last distribution, from which it cannot always be distinguished by elementary methods if the original data are not available. If, for instance, the frequencies of Table XII. had been given by five-year intervals 08
