and Cornil, "Contribution à l'étude de la patria potestas," in _Nouv. rev. hist. de droit_, XXI, 416-85 (Paris, 1897). Gide's excellent _Étude sur la condition privée de la femme_ (2d ed., Paris, 1885) deals with the laws of Greece, Rome, and other nations. Poste's edition of Gaius's _Institutionum juris civilis commentarii quatuor_ (Oxford, 1875) is an indispensable source; and among legal treatises are particularly to be commended Muirhead's _Introduction to the Private Law of Rome_ (Edinburgh, 1886); Puchta's _Institutionen_; Moyle's _Institutionum Libri_ (Oxford, 1890); Rein, _Privatrecht_ (Leipzig, 1836); and especially Sohm's _Institutes_ (Oxford, 1892), by far the best work on the subject for historical purposes, showing the rare insight, clearness of analysis, and vigorous style peculiar to the author. Most readers will find the short _Introduction_ of Hadley and the excellent _Outlines_ of Professor Morey sufficient. For the general subject of marriage and the family the _Zeitschrift für vergleichende Rechtswissenchaft_ (Stuttgart, 1878-96) is indispensable; while the _Kritische Vierteljahresschrift für Gesetzgebung und Rechtswissenschaft_ and the _Zeitschrift für Ethnologie_ are also of constant service. For the literature of Arabian and Hebrew matrimonial institutions, respectively, see Bibliographical Notes II and IV. The student who has not yet seriously attacked the literature of the subject will do well to begin with the following: Tylor, "On a Method of Investigating the Development of Institutions, Applied to Laws of Marriage and Descent," in _Journal of Anth. Inst._, XVIII, No. 3; Bernhöft's "Zur Geschichte des europäischen Familienrechts," in _ZVR._, VIII, 1-27, 161-221, 384-405; in connection with his "Principien des europäischen Familienrechts," _ibid._, IX, 392-444; Friedrichs, "Familien-Stufen und Eheformen," _ibid._, X, 189-281; the first two chapters of Posada's _Théories modernes_ (Paris, 1896); and the first three chapters of Botsford's _Athenian Constitution_ (Boston, 1893), one of the ablest contributions to comparative institutions. This is supplemented by H. E. Seebohm's _Structure of Greek Tribal Society_ (London and New York, 1895). For summaries of the results of investigations, from different points of view, Delbrück's "Das Mutterrecht bei den Indogermanen," in _Preussische Jahrbücher_, XCVII, 14-27 (Berlin, 1895), may be compared with Dargun's _Mutterrecht und Vaterrecht_ (Leipzig, 1892), containing a criticism of the views of many recent writers.]
