Vill   PECULIARITIES OF THE DIGITS

125

to C + Z, in which C are the causes common to both, and X and Z the special ones. In exact proportion as X and Z diminish, and C becomes of overpowering effect, so does the closeness of the relationship increase. When X and Z both disappear, the result is identity of character. On the other hand, when C disappears, all relationship ceases, and the variations of the two objects are strictly independent. The simplest case is that in which X and Z are equal, and in this, it becomes easy to devise a scale in which 0° shall stand for no relationship, and 1000 for identity, and upon which the intermediate degrees of relationship may be marked at their proper value. Upon this assumption, but with some misgiving, I will attempt to subject the digits to this form of measurement. It will save time first to work out an example, and then, after gaining in that way, a clearer understanding of what the process is, to discuss its defects. Let us select for our example the case that brings out these defects in the most conspicuous manner, as follows

Table V. tells us that the percentage of whorls in the right ring - finger is 4 5, and in the left ring - finger 31. Table VIa tells us that the percentage of the double event of a whorl occurring on both the ring-fingers of the same person . is 26. It is required to express the relationship between the right and left ring-fingers on a centesimal scale, in which 0° shall stand for no relationship at all, and 1000 for the closest possible relationship.

If no relationship should exist, there would never-
