PREFACE TO THE SECOND EDITION

INTRODUCTION

      Origin and object of book.

VARIETY OF HUMAN NATURE

      Many varieties may each be good of its kind; advantage of variety; some peculiarities are, however, harmful.

FEATURES

      Large number of elements in the human expression; of touches in a portrait; difficulty of measuring the separate features; or of selecting typical individuals; the typical English face; its change at different historical periods; colour of hair of modern English; caricatures.

PORTRAITURE

      (See Appendix for three Memoirs describing successive stages of the method).--Object and principle of the process; description of the plate--composites of medals; of family portraits; of the two sexes and of various ages; of Royal Engineers; the latter gives a clue to one direction in which the English race might be improved; of criminals; of the consumptive; ethnological application of the process.

BODILY QUALITIES

      Anthropometric Committee; statistical anomalies in stature as dependent on age; town and rural population; athletic feats now and formerly; increase of stature of middle classes; large number of weakly persons; some appearances of weakness may be fallacious; a barrel and a wheel; definition of word "eugenic."

ENERGY

      It is the attribute of high races; useful stimuli to activity; fleas, etc.; the preservation of the weakly as exercises for pity; that of foxes for sport.

SENSITIVITY

      Sensation and pain; range and grades of sensation; idiots; men and women; the blind; reading by touch; sailors; paucity of words to express gradation.

SEQUENCE OF TEST WEIGHTS

      (See also Appendix, p. 248).--Geometric series of weights; method of using them; the same principle is applicable to other senses; the tests only measure the state of faculties at time of trial; cautions in constructing the test weights; multiplicity of the usual perceptions.

WHISTLES FOR AUDIBILITY OF SHRILL NOTES

      (See also Appendix, p. 252).--Construction of them; loss of power of hearing high notes as age advances; trials upon animals; sensitivity of cats to high notes; of small dogs and ponies.

ANTHROPOMETRIC REGISTERS

      Want of anthropometric laboratories; of family records; opportunities in schools; Admiralty records of life of each seaman; family registers (see also 220); autotypes; medical value of ancestral life-histories (see also 220); of their importance to human eugenics.

UNCONSCIOUSNESS OF PECULIARIIES

      Colour blindness usually unsuspected; unconsciousness of high intellectual gifts; of peculiarities of mental imagery; heredity of colour blindness in Quakers; Young and Dalton.

STATISTICAL METHODS

      Objects of statistical science; constancy and continuity of statistical results; groups and sub-groups; augival or ogival curves; wide application of the ogival; method; example; first method of comparing two ogival groups; centesimal grades; example; second method of comparing ogival groups; statistical records easily made with a pricker.

CHARACTER

      Caprice and coyness of females; its cause; observations of character at schools; varieties of likings and antipathies; horror of snakes is by no means universal; the horror of blood among cattle is variable.

CRIMINALS AND THE INSANE

      Peculiarities of criminal character; some of them are normal and not morbid; their inheritance as in the Jukes family; epileptics and their nervous instability; insanity; religious rapture; strange views of the insane on individuality; their moody segregation; the religious discipline of celibacy, fasting and solitude (see also 125); large field of study among
