nd solitude (see also 125); large field of
study among the insane and idiotic.

GREGARIOUS AND SLAVISH INSTINCTS

Most men shrink from responsibility; study of gregarious
animals: especially of the cattle of the Damaras; fore-oxen
to waggon teams; conditions of safety of herds; cow and
young calf when approached by lions; the most effective
size of herd; corresponding production of leaders; similarly
as regards barbarian tribes and their leaders; power of
tyranny vested in chiefs; political and religious persecutions;
hence human servility; but society may flourish without
servility; its corporate actions would then have statistical
constancy; nations who are guided by successive orators,
etc., must be inconstant; the romantic side of servility; free
political life.

INTELLECTUAL DIFFERENCES

Reference to _Hereditary Genius_.

MENTAL IMAGERY

Purport of inquiry; circular of questions (see Appendix
for this); the first answers were from scientific men,
and were negative; those from persons in general society
were quite the reverse; sources of my materials; they are
mutually corroborative. Analysis of returns from 100
persons mostly of some eminence; extracts from replies of
those in whom the visualising faculty is highest; those in
whom it is mediocre; lowest; conformity between these
and other sets of haphazard returns; octile, median, etc.,
values; visualisation of colour; some liability to exaggeration;
blindfold chess-players; remarkable instances of visualisation;
the faculty is not necessarily connected with keen sight or
tendency to dream; comprehensive imagery; the faculty in different
sexes and ages; is strongly hereditary; seems notable among
the French; Bushmen; Eskimo; prehistoric men; admits of being
educated; imagery usually fails in flexibility; special and generic
images (see also Appendix); use of the faculty.

NUMBER-FORMS

General account of the peculiarity; mutually corroborative
statements; personal evidence given at the Anthropological
Institute; specimens of a few descriptions and
illustrative woodcuts; great variety in the Forms; their
early origin; directions in which they run; bold conceptions
of children concerning height and depth; historical
dates, months, etc.; alphabet; derivation of the Forms
from the spoken names of numerals; fixity of the Form
compared to that of the handwriting; of animals wor
