General character of the information on this subject indicated, and some controversy contained in this chapter justified (pp. [89-91]).—Problem set forth (pp. [91], [92]).—Statements (pp. [92-100]).—Local differences between different groups of tribes in sexual matters (pp. [100], [101]).—Three points investigated: (1) The husband's definite sexual over-right and control over his wife involving his consent in all cases. Otherwise adultery considered a crime (pp. [101-103]).—(2) Chastity in general; its slight recognition (pp. [104], [105]).—(3) Regulated licence (pp. [105-107]).—Its chief form: the Pirrauru practice (pp. [108], [109]).—A detailed discussion of the latter showing its lack of the features of "group marriage" (pp. [109-123]).—In general all sexual licence regulated and devoid of the character of promiscuity and disorder (pp. [123], [124]).—Digression on sexual jealousy among the Australian aborigines (pp. [124-131]).

CHAPTER V
MODE OF LIVING

I. The relation of the family unit to the tribal and territorial organization of the aboriginal society (pp. [132] sqq.).

Terminology (pp. [134], [135]).—Statements (pp. [136-149]).—Rough survey (pp. [149], [150]).—The territorial unit, the local group a body of people possessing in common a tract of country and inhabiting it to the exclusion of anybody else (pp. [150-152]).—Three different forms of possession of land in Australia (pp. [152], [153]).—Idea of rights in a portion of land probably to a great extent of magico-religious character (p. [153]).—The mode of living, the tribal division varying according to local conditions and with opportunities of food-supply. In the majority of tribes (especially those of the arid regions) small groupings of about one to three families usual (pp. [150-157]).

II. The internal structure of the local group, with reference to single families (pp. [158] sqq.).

Statements (pp. [158-165]).—Disposition of camps, the mode of occupying the huts and other functions of daily life subject to strict rules pointing to the isolation of the single families (pp. [165-167]).

CHAPTER VI
DISCUSSION OF KINSHIP

I. Theoretical analysis of this concept (pp. [168] sqq.).

Importance of adapting sociological concepts to those social conditions to which they are applied, exemplified on the concept of kinship (pp. [168], [169]).—Necessity of giving a definition of kinship for scientific use (pp. [169-171]).—The present discussion specially directed to suit the Australian evidence (pp. [171], [172]).—Necessary and sufficient conditions for admitting the existence of individual parental kinship in any given society (pp. [172-174]).—Further features thereof to be looked for in the variable social conditions and in the data of "collective psychology"; "collective ideas" held about kinship and "collective feelings" referring to it (pp. [174-176]).—Preliminary definition of kinship (p. [176]).—Analysis of the concept of consanguinity (pp. [176] sqq.).—Modern European idea of kinship conceived in terms of consanguinity (p. [177]).—Physiological and social consanguinity (pp. [178-182]).—Exact definition of the latter (p. [182]).—Kinship not always based upon ideas of community of blood. Common features of the ideas underlying kinship (pp. [182], [183]).—Normative ideas referring to kinship. Descent (pp. [183-185]).—Analysis of the legal side of kinship (pp. [185], sqq.).—Legal only one of the aspects of kinship (p. [185]).—In primitive societies in particular kinship not a legal relationship (pp. [185], [186]).—Discussion of some opinions thereon (Mr. Thomas, Prof. Dargun, Prof. Frazer) (pp. [186-190]).—Restricted use of the term legal in the Australian aboriginal society (pp. [190], [191]).—Justification of the study of the emotional characteristics of kinship (pp. [191] sqq.).—Importance of feelings in the task of characterizing any personal relationship. "Collective feelings" (pp. [191], [192]).—The presence in the Australian ethnographic material of objective facts which express the collective feelings referring to kinship (pp. [192-194]).—Analysis of these facts (pp. [194-197]).—Mutual dependence of collective ideas and collective feelings referring to kinship (pp. [197], [198]).—Summary (pp. [198], [199]).—Critical survey of some definitions of kinship given by other authors (Morgan, MacLennan, Mr. E. S. Hartland, Dr. Rivers, Fison and Howitt, M. von Gennep, Prof. Durkheim, Prof. Westermarck, Sir Laurence Gomme) (pp. [199-206]).—Two additional remarks (pp. [206], [207]).

II. Some examples of kinship ideas suggested by the Australian folklore (pp. [207] sqq.).
