Thus the Babylonian Talmud is to be found only in two MSS. (Harl. 5508 and Add. 25,717) both of them including 11 Tractates, hardly a third part of the whole work. Indeed poor “Rabbinus Talmud” had to go to the _auto de fé_ on so many occasions that one cannot wonder if only disjointed limbs are to be found of him in libraries. The only complete MS. copy which escaped this vandalism is that in the Royal Library in Munich, from which Mr. Rabbinowicz has edited his monumental work, _Variae Lectiones of the Talmud_. All other libraries, Oxford included, have to be satisfied with fragments. Still worse, as it is seen, fared the Jerusalem Talmud, and excepting the well‐known copy in Leyden from which the Venice edition was prepared, not even fragments of this Talmud are to be found in the majority of libraries. To my knowledge it is only the British Museum which can boast of the Jerusalem Talmud in MS. extending over _Order of Seeds_ and one tractate of _Order of Festivals_(221) (Or. 2122‐24) with commentaries of R. Solomon Syrillo, the first few pages of which were edited by Dr. Lehmann of Mayence. The Museum also possesses a great part of the Tosephta extending over 14 Tractates (Add. 27,296). Of Midrashim we find in the Museum two excellent manuscripts of the Genesis _Rabbah_, one of the Leviticus _Rabbah_, and one of the _Siphra_ and the _Siphré_ (Add. 27,169 and 16,406), besides two copies of the Midrash _Haggadol_ and other Aagadic collections brought from Yemen. The _Midrash_ by Machir b. Abba Mari to the minor prophets included in the Harleian collection (5704) is unique. Of Liturgies, besides a great number of MSS. representing the most peculiar rites, I shall mention the Machzor(222) Vitri (Add. 27,200‐1) composed by the disciples of R. Solomon b. Isaac, and forming in itself almost a small library. For, apart from the prayers for festivals and week days which gave it its title, it includes, besides the _Sayings of the Fathers_ with a large commentary, three of the Minor Tractates of the Talmud, many responses by German and French Rabbis, and a whole series of religious hymns by German and Spanish authors, and many other literary pieces. Cabbalah is represented by various valuable writings of the pre‐ Zoharistic time (see for instance Add. 15,299) and the works of R. Moses de Leon and R. Abraham Abulafia. Of Poetry, I shall point here to the Tarshish of R. Moses Ibn Ezra, the Makames by Judah Al Charisi (Add. 27,122), and the Divan of R. Abraham of Bedres (Add. 27,188). Of works relating to grammar and lexicography, I may refer to a Codex (Add. 27,214) which contains the lexicon of R. Menahem ben Saruk, which is considered as the oldest Hebrew MS. in the Museum, dating from the year 1091. Of historical works, I mention the chronicle of R. Joseph the Priest (Add. 27,122) and the letter of R. Sherira Gaon (Arundel 51), the oldest existing copy of this work (1189), which was edited by Dr. Neubauer in his _Mediæval Jewish Chronicles_.
