his scholarship in the ten volumes of his Jahrbücher (Frankfort-on-the-Main, 1874–90). He contributed almost the entire material to these Jahrbücher—the longer and shorter essays as well as the numerous criticisms on new books. Many of these essays have also been printed separately. Bible Beiträge zur Erklärung des Buches Hosea (Jahrb. v.-vi. 1-62) Historische Basis des Buches Ruth (v.-vi. 63-70) Das Apokryphische Susannabuch (iii. 1-69) Die Epistolischen Apokryphen und die Apokryphischen Zusätze zum Buche Daniel. Talmud Die Talmudischen Tractate über Trauer um Verstorbene (i. 1-57) Fremdsprachliche Wörter in den Talmuden und Midraschim (i. 123-210) Die Entstehungsgeschichte des Babylonischen Talmuds als Schriftwerkes (ii. 1-123) Verschollene Baraitas und Midraschim (ii. 124-133) Entstehung und Ursprünglicher Inhalt des Tractates Abot (vii. 1-17) Eingeschaltete Partien im Babylonischen Talmud (viii. 59-60). History Adiabene (i. 58-86) Das Geschlecht der Treves (i. 87-122) Die Polemik für und gegen Maimuni im Dreizehnten Jahrhundert (iv. 1-33) Zur Gesch. der Jüdisch-Ethischen Literatur des Mittelalters (v.-vi. 71-93) Sprüchwörter in der Nachtalmudischen Literatur des Judenthums (vii. 18-30). Bibliographical works Brüll's range of reading and critical insight constituted him an important reviewer of new books in the field of Jewish science. His Jahrbücher contain 183 reviews, all of which illuminate more or less the subjects with which they deal. In 1890 Brüll undertook a continuation of the Hebräische Bibliographie, edited by Moritz Steinschneider, under the title Central-Anzeiger für Jüdische Literatur; but only one volume appeared (Frankfurt am Main, 1891), as the undertaking was cut short by Brüll's death. At the instance of Steinschneider, the Zunz-Stiftung had commissioned Brüll to add a supplement to Leopold Zunz's Gottesdienstliche Vorträge, the basic work of modern Jewish science. Steinschneider remarked in his preface to the second edition of the work in question (xvi.): "Dr. Brüll appeared to me to possess the rare combination of ability and leisure, zeal and perseverance, requisite for editing such a supplement.'" Brüll had intended to devote his whole scholarship to this undertaking. The scattered notes that were found in his papers after his death were in part incorporated in the second edition of the Gottesdienstliche Vorträge (ib. 1892). Brüll was among the few German scholars who also wrote in Hebrew, as may be seen by his many contributions to the Hebrew periodicals Bet-Talmud, Bet ha-Midrash, Ha-Karmel, and Oẓar ha-Sifrut. Of these, Toledot Shabbethai Ẓebi (Wilna, 1879) and Ner la-Maor, a biography of Aaron Worms, in Ozar ha-Sifrut, ii. 20-31, deserve special mention. Brüll also
