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 working in constant patterns; of track of eye when searching for lost objects; occasional origin from figures on clock; from various other sources; the non-decimal nomenclature of numerals; perplexity caused by it. Description of figures in Plate I.; Plate II.; Plate III.; Plate IV. Colours assigned to numerals (see 105); personal characters; sex; frequency with which the various numerals are used in the Talmud.

COLOUR ASSOCIATIONS

(Description of Plate IV. continued) Associations with numerals; with words and letters; illustrations by Dr. J. Key; the scheme of one seer unintelligible to other seers; mental music, etc.

VISIONARIES

Sane persons often see visions; the simpler kinds of visions; unconsciousness of seers, at first, of their peculiarity; subsequent dislike to speak about it; imagery connected with words; that of Mrs. Haweis; automatic changes in dark field of eye; my own experiences; those of Rev. G. Henslow; visions frequently unlike vivid visualisations; phantasmagoria; hallucinations; simile of a seal in a pond; dreams and partial sensitiveness of brain; hallucinations and illusions, their causes; "faces in the fire," etc.; sub-conscious picture-drawing; visions based on patched recollections; on blended recollections; hereditary seership; visions caused by fasting, etc.; by spiritual discipline (see also 47); star of Napoleon I.; hallucinations of great men; seers commoner at some periods than at others; reasons why.

NURTURE AND NATURE

Their effects are difficult to separate; the same character has many phases; Renaissance; changes owing merely to love of change; feminine fashions; periodical sequences of changed character in birds; the interaction of nurture and nature.

ASSOCIATIONS

Derived from experience; especially from childish recollections (see 141); abstract ideas; cumulative ideas, like composite portraits (see also Appendix, "Generic Images," p. 229); their resemblance even in details.

PSYCHOMETRIC EXPERIMENTS

Difficulty of watching the mind in operation; how it may be overcome; irksomeness of the process; tentative experiments; method used subsequently; the number of recurrent associations; memory; ages at which associations are formed; similarity of the associations in persons of the same country and class of society; different descriptions of associations, classified; their relative frequency; abstract ideas are slowly formed; multifariousness of sub-conscious operations.

ANTECHAMBER OF CONSCIOSNESS

Act of thinking analysed; automatic mental work; fluency of words and of imagery; processes of literary composition; fluency of spiritual ideas; visionary races of men; morbid ideas of inspiration (see Enthusiasm).

EARLY SENTIMENTS

Accidents of education, religion, country, etc.; deaf-mutes and religious ritual; religion in its essentials; all religious teachers preach faith and instil prejudices; origin of the faculty of conscience; evolution is always behindhand; good men of various faiths; the fear of death; terror is easily taught; gregarious animals (see also 47); suspiciousness in the children of criminals; Dante and contemporary artists on the terrors of hell; aversion is easily taught, Eastern ideas of clean and unclean acts; the foregoing influences affect entire classes.

HISTORY OF TWINS

It supplies means of comparing the effects of nurture and nature; physiological signification of twinship; replies to a circular of inquiries; eighty cases of close resemblance between twins; the points in which their resemblance was closest; extracts from the replies; interchangeableness of likeness; cases of similar forms of insanity in both twins; their tastes and dispositions; causes of growing dissimilarity mainly referred to illness; partly to gradual development of latent elements of dissimilarity; effect of childish illnesses in permanently checking growth of head; parallel lives and deaths among twins; necessitarianism; twenty cases of great dissimilarity; extracts from the replies; evidence of slight exaggeration; education is almost powerless to diminish natural difference of character; simile of sticks floating down a brook; depth of impressions made in childhood; they are partly due to
