[Footnote 286: On the more purely juristic aspects of the Empire the best work in English is Howard, The German Empire (Chap. 2, on "The Empire and the Individual States"). A very useful volume covering the governments of Empire and states is Combes de Lestrade, Les monarchies de l'Empire allemand (Paris, 1904). The monumental German treatise is P. Laband, Das Staatsrecht des deutschen Reiches (4th ed., Tuebingen, 1901), in four volumes. There is a six-volume French translation of this work, Le droit public de L'Empire allemand (Paris, 1900-1904). Other German works of value are: O. Mayer, Deutsches Verwaltungsrecht (Leipzig, 1895-1896); P. Zorn, Das Staatsrecht des deutschen Reiches (2d ed., Berlin, 1895-1897); and A. Arndt, Das Staatsrecht des deutschen Reiches (Berlin, 1901). There is a four-volume French translation of Mayer's important work, under the title Le droit administratif allemand (Paris, 1903-1906). Two excellent brief German treatises are: P. Laband, Deutsches Reichsstaatsrecht (3d ed., Tuebingen, 1907), and Hue de Grais, Handbuch der Verfassung und Verwaltung in Preussen und dem deutschen Reiche (18th ed., Berlin, 1907). The most recent work upon the subject is F. Fleiner, Institutionen des deutschen Verwaltungsrechts (Tuebingen, 1911). A suggestive monograph is J. du Buy, Two Aspects of the German Constitution (New Haven, 1894).] IV. THE EMPIRE AND THE STATES (p. 205)
