This discussion concerns itself with an investigation of tests for sensibility among "normal" persons.
From among the tests originally devised by Henry Head only a few have been selected here for intensive study, and these were arbitrarily chosen because of their wider clinical use and because of their easy applicability. They refer mostly to cortical sensory functions.
For my objective I have set out to determine the number and types of errors that "normal" persons may be prone to make, in order that I might use the observations for purposes of comparison with the results obtained from testing pathologic material.
It will be shown that "normal" subjects make many errors identical with those found in pathologic cases. In this paper the results demonstrate the fact that "interpretation" of pathologic sensory observations is most difficult and always doubtful unless one uses the responses from "normal" subjects as a standard by which
