It is regrettable that the list has not been published more widely and used in a variety of connections. It seems probable that these significant nouns may in many cases be paralleled by natural units of mental organization-atoms in the human compound. I venture to suggest also, as at least a provisional principle of organization, the instincts or original tendencies of man as a species, it being my opinion that some of the terms of the above list refer to rather complex concatenations of traits in man's nature which have only the artificial unity of producing some defined result in human life." Partridge, in his "Outline of Individual Study," gives an account of methods whereby the teacher may assist the young child in discovering his or her particular physical and mental constitution. The book contains a brief outline for such study and enumerates many pages of words descriptive of human nature. The main aspects of the mental life of children are taken up in successive chapters and discussed in a general way, with suggestions in the way of tests, problems, questions, points of observation, etc. The "Family History Book" (Bulletin No. 7) of the Eugenics Record Office contains a scheme, arranged by Drs. Hoch and Amsden, for the examination of the personality of persons suspected of mental abnormality. This scheme is further elaborated by Wells in an outline to be referred to at a later point in this chapter. In the "Trait Book" (Bulletin No. 6) of this same office there is to be found a long list of traits descriptive of human beings, including physical and physiological as well as nervous and mental characteristics. These traits are classified for convenient reference and record according to a decimal key. The pamphlet also contains classified lists of diseases, crimes, and occupations. Various other bulletins issued by the Eugenics Record Office will also be found both interesting and suggestive to those interested in the study of self-analysis, heredity and individual differences. They contain nothing, however, of immediate vocational applicability.
