It will be readily understood by other readers that, as the limits
assigned to this paper permit the insertion of but a small part of the
material already collected and of the notes of study made upon
that accumulation, it can only show the general scope of the work
undertaken, and not its accomplishment. Such extracts from the
collection have been selected as were regarded as most illustrative,
and they are preceded by a discussion perhaps sufficient to be
suggestive, though by no means exhaustive, and designed to be for
popular, rather than for scientific use. In short, the direction to
submit a progress-report and not a monograph has been complied with.




DIVISIONS OF GESTURE SPEECH.

These are corporeal motion and facial expression. An attempt has been
made by some writers to discuss these general divisions separately,
and its success would be practically convenient if it were always
understood that their connection is so intimate that they can never
be altogether severed. A play of feature, whether instinctive or
voluntary, accentuates and qualifies all motions intended to serve
as signs, and strong instinctive facial expression is generally
accompanied by action of the body or some of its members. But, so
far as a distinction can be made, expressions of the features are the
result of emotional, and corporeal gestures, of intellectual action.
The former in general and the small number of the latter that
are distinctively emotional are nearly identical among men from
physiological causes which do not affect with the same similarity
