Excerpt from The Constant Error of Touch Localization In these tables it will be observed that the constant errors in the individual tests differ greatly. In some there is an apparent tendency to locate toward the pelvis, in others toward the knee; in one there is a tendency to locate toward the dorsal surface and in the other nine toward the anterior surface of the leg. The angular relations of the constant error determinations to the supposed nerve course in these ten series greatly differ, ranging from 24 Degrees to 231 Degrees on the right leg, and from 219 Degrees to 297 Degrees on the left leg. Within the artificial angular limits there is only one constant error direction on the right and none on the left side, four on the right and five on the left being outside of the supposed angular directions. In only three tests is there a predominance of localizations in the direction of the artificially set angular limits, and in the other seven tests there is a superiority of localization in the spaces at right angle to the artificially set directions. For the total of ten tests, therefore, there is a superiority in direction away from the space amounting to over 100 per cent. Summary - The method of calculation of constant error by angular limits is too inexact to warrant its use except as a possible qualitative method for preliminary work. The constant error tendency in the five locations selected for the present series of tests is in only one place in the supposed direction of the innervating nerve, whether this tendency be measured by the usual and more exact means or by the method of angular limits used by Ponzo. Conclusions regarding the constancy of direction of constant errors must be radically changed to conform to the facts.
