reactions must fall into the unclassified group. We submit the
following examples:

_music--listen_
_smooth--suave_
_sour--curdled_
_earth--mound_

Another type of reactions found in the unclassified group, though also
normal, yet not obviously so until explained by the subject, is
represented by those which originate from purely personal experiences,
such as the following, given by normal subjects:

_blossom--T....._
_hammer--J....._

The first of these reactions is explained by the subject's acquaintance
with a young lady, Miss T...., who has been nick-named "Blossom," and
the second is explained by the subject's having among her pupils at
school a boy by the name of J.... Hammer.

It would be difficult to estimate the proportion of such reactions in
the unclassified group, but we have gained the general impression that
it is small. An attempt to place them in a separate group could be
made only with the aid of explanations from the subjects; such aid in
the case of insane subjects is generally unreliable. Moreover, to
class these reactions as strictly normal would perhaps be going too
far, since their general value is obviously inferior to that of the
common reactions; and in any case in which they are given in unusually
large numbers they must be regarded as manifestation of a tendency to
