necessary to explain to correspondents and collaborators whom it may
reach, that this is not the comprehensive publication by the Bureau
of Ethnology for which their assistance has been solicited. With this
explanation some of those who have already forwarded contributions
will not be surprised at their omission, and others will not desist
from the work in which they are still kindly engaged, under the
impression that its results will not be received in time to meet with
welcome and credit. On the contrary, the urgent appeal for aid before
addressed to officers of the Army and Navy of this and other nations,
to missionaries, travelers, teachers of deaf-mutes, and philologists
generally, is now with equal urgency repeated. It is, indeed, hoped
that the continued presentation of the subject to persons either
having opportunity for observation or the power to favor with
suggestions may, by awakening some additional interest in it, secure
new collaboration from localities still unrepresented.

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 distinctivel
