*Repetition of Previous Stimulus.*--Here we place any reaction
which is a repetition of any previous stimulus from amongst the ten
next preceding, at the same time placing *repetition of preceding
stimulus* under a separate heading.

*Neologisms.*--Here we place the newly coined words, so commonly
given by the insane, excepting such as possess a sound relationship to
the stimulus word, for which, as already stated, a special place in
the classification has been provided.

Neologisms might be divided into three types, as follows: (1) those
which arise from ignorance of language (_comfort--uncomfort,
short--diminiature_); (2) distortions of actual words, apparently
of pathological origin and not due to ignorance (_hungry--foodation,
thief--dissteal_); and (3) those which seem to be without any
meaning whatever (_scack, gehimper, hanrow, dicut_). It is,
however, impossible to draw clear-cut distinctions between these
types, and for this reason we have made no provision in our
classification for such division.

*Unclassified Reactions.*--This group is important, in the first
place, because it is numerically a large one, and in the second place,
because it contains certain fairly definite types of reactions which
are placed here for the sole reason that we have not been able to find
strictly objective criteria for their differentiation from other
types.

It has already been stated that the frequency tables, even together
with the appendix, fail to exhaust all normal possibilities of
association, so that a certain small number of perfectly normal
